How to Win Enemies and Hurt People. A Detailed Guide to the Mechanics of DotA2.

How many enemies do you face in a DotA2 match? Most players would say 'five', but the most dangerous enemy you face isn’t even on the other team. The true enemy in DotA2 is your own ignorance.

Most players will never be able to defeat this foe because they will never even acknowledge its presence. This guide will only be of any use to a player that has recognized their own ignorance as the opponent they must overcome to improve. If you’re ready to admit that you don’t know enough about DotA2, proceed to memorize the data in this guide.

Foreword

This guide is intended for intermediate and veteran DotA2 players that want to gain a better understanding of the more complex rules of the game. This guide is not intended for new players (there are plenty of these already). Like DotA2, this guide is a work in progress. I will continue to update this guide as my own understanding of DotA2 expands and as new heroes and features are added to the game. I have tested (and retested…) everything in this guide, but the rules of DotA2 are modified with some regularity. If anything in this guide does not work as described in DotA2 please let me know in the comments. It should be noted that DotA2 is not DotA. There are several rule changes that veterans may not be aware of. The existence of such changes are assumed to be intentional by this guide (since knowing the mind of Icefrog is impossible). This guide will never describe how something should work; it will always describe exactly how it does work.

Understanding Damage Types

This is the most important section in this guide. If you are only going to read and understand one section, ensure that it is this one. If you do not understand the different types of damage that can be dealt in DotA2 you will not understand many things in this guide (or even why many things are mentioned in this guide). This section describes how the different types of damage in DotA2 normally operate, but you'll come to understand that there really is no true "normal" in DotA2. Memorize these rules and assume they apply to everything... until you read otherwise in a specific Hero's section. The tables at the end of this section include every hero spell or ability that does not deal magical damage as a reference.

Physical damage is caused by all attacks from all units and by some spells and passive abilities. An “attack” is triggered when a hero or unit is ordered to attack another hero or unit with a right-click (attack order) or the “A” key (attack move order). Attacks can miss because of evasion or miss chance (including misses caused by terrain). Physical damage is reduced by both Armor and Damage Block. Armor points are not considered when calculating cleave damage (damage caused by cleaves such as Sven’s “Great Cleave”, Kunkka’s “Tidebringer”, and items like “Battle Fury”). Damage Block affects cleave damage normally. The area of effect of a cleave effect is circular, where the length of the radius is equal to the cleave range of a given cleave ability. The circular area of effect is always placed directly adjacent to the attacking unit and oriented in the direction that the attacking unit was facing when the attack was made. The diameter of the aforementioned circle runs through the attacking unit and the unit being attacked. Armor type (hero, structure, basic, etc…) is still considered when calculating cleave damage. Physical splash damage (from ranged attacks such as Dragon Knight’s “Splash Attack” passive ability at level 2 and 3 of his ultimate “Elder Dragon Form” or Shadow Shaman’s “Mass Serpent Ward”) is reduced as normal. Units with negative Armor values receive an increased amount of physical damage. Physical damage is totally unaffected by Magic Resistance and cannot affect ethereal units. Spells that deal physical damage cannot target Spell Immune units directly. Physical spells and passive abilities can only affect Spell Immune units if they are capable of piercing Spell Immunity. Unlike physical attacks, physical spells cannot be avoided with Evasion (from skills or items). Physical spell damage is reduced by damage block.

Magical damage is caused primarily by spells and some passive abilities (not all spells deal magic damage). Magic damage is reduced by Magic Resistance and does not affect Spell Immune units. Magic damage is amplified against ethereal units by 1.4x. Magical damage does not affect mechanical units like siege creeps. Lifesteal effects from items, spells or passive abilities still function against Spell Immune units. Spells that cause magical damage cannot target or damage Spell Immune units. Items with offensive active abilities cannot target Spell Immune units and do not affect them. Every spell in the game that IS NOT listed in one of the two tables in the next sections of this guide deals magical damage (if they deal any damage at all). Most of the spells in DotA2 deal magical damage.

Pure damage is a type of magical damage and it shares all properties not mentioned in this description with that damage type. Pure damage is unaffected by Magic Resistance or Magic Amplification. This means that pure damage always does the exact amount of damage specified in the in-game tooltip. Pure damage does the same amount of damage to ethereal units as it does to non-ethereal units (it is not amplified). A few rare Pure spells ignore Spell Immunity (like Black King Bar, Omniknight’s “Repel”, Lifestealer’s “Rage”, or the passive Spell Immunity that Ancient creeps have). Some rare cases exist in which a pure damage spell can damage a Spell Immune unit. Example: Bane cast's "Nightmare" on Drow Ranger. Omniknight casts "Repel" on Drow Ranger. Drow Ranger continues to take damage because "Nightmare" is pure damage, but "Nightmare" could not have been cast on Drow Ranger if she had been Spell Immune when Bane had attempted the cast.

The following Pure spells pierce Spell Immunity:

• Abbadon's "Mist Coil" (only piercies allied Spell Immunity, including Abbadon's)
  
• Bloodseeker's "Rupture"
  
• Doom's "Doom"
  
• Enigma's "Midnight Pulse"
  
• Invoker's "Sun Strike"
  
• Lina's "Laguna Blade" with Aghanim's Scepter
  
• Pudge's "Meat Hook"
  
• Queen of Pain's "Sonic Wave"
  
• Templar Assassin's "Psi Blades"
  
• Vengeful Spirit's "Wave of Terror"
  
• Warlock's Golem's "Flaming Fists"
  
• Winter Wyvern's "Arctic Burn"

HP modifications are not based on any other damage type. HP modifications directly subtracts hit points from units that it affects, ignoring Spell Immunity, Armor, Magic Resistance, Damage Block, Damage Reduction/Amplification and Ethereal states. This means that hp modifications always remove the exact amount of hit points specified in the in-game tooltip (this amount can be conditional). In short, almost nothing in DotA2 protects you or your enemies from hp modifications. Invulnerability does protect from hp modification. Unlike all other damage types, hp modifications do not count as being attacked and as such they will not interrupt items (such as Blink Dagger, Heart of Tarrasque, Clarity, Salve and Bottle) or trigger any other on-attack effects (like Timbersaw's “Reactive Armor”). Hp modifications cannot kill you or an enemy in any circumstance.

A noteworthy commonality:

None of the damage types in DotA2 can innately damage structures when used in spells or abilities. Spells and abilities must be designated in the game with a specific flag to be able to damage structures. Example: Leshrac’s “Diabolic Edict” deals physical damage. Leshrac’s “Diabolic Edict” can damage structures. THESE TWO FACTS ARE NOT RELATED IN ANY WAY.

Physical Damage Subtypes

Unlike the previous section on damage types, this section is FAR less important. If you want a comprehensive understanding of how every unit in the game deals damage when it attacks you can start here. Otherwise, feel free to skip this section.

Physical damage is divided into several subtypes that are not referenced in DotA2’s user interface. These damage subtypes are based on Warcraft 3’s damage types; although there are a few differences in the way they are assigned and named in DotA2. Almost all physical damage referenced in this guide is Hero type damage. However, many units summoned or frequently controlled by heroes do not deal Hero type physical damage. Understanding the damage types dealt by summoned units is the key to understanding their best applications. The physical damage types in DotA2 are:

• Light (known as “Chaos” in WC3)
  
• Hero
  
• Basic (known as “Normal” in WC3)
  
• Pierce
  
• Siege

Physical damage type is compared to armor types to calculate the amount of damage that is dealt from an attack before armor reduction. The armor types in DotA2 are:

• Weak (known as “Light” in WC3)
  
• Basic (known as “Medium” in WC3)
  
• Strong (known as “Heavy” in WC3)
  
• Structure (known as “Fortified” in WC3)
  
• Hero
  
• Soft (known as “Unarmored” in WC3)

The following table illustrates the percentage of damage dealt by the aforementioned attack types versus the similarly aforementioned armor types:

	Weak	Basic	Strong	Structure	Hero	Soft
Light	100%	100%	100%	40%	100%	100%
Hero	100%	100%	100%	50%	100%	100%
Basic	100%	150%	125%	70%	75%	100%
Pierce	200%	75%	75%	35%	50%	150%
Siege	100%	50%	125%	150%	75%	100%

Noteworthy examples of creeps, units, and spells that deal damage other than “Hero”:

Light: Roshan, Warlock’s Golem, Invoker’s Forged Spirits, Broodmother’s Spiderlings, Centaur Conqueror, Satyr Tormentor, Wildwing Ripper, Hellbear Smasher

Basic: Melee Lane Creeps (normal and mega), Enigma’s Eidolons, Nature’s Prophet’s Treants, Broodmother’s Spiderites, Lycan’s Wolves, Lone Druid’s Bear, Necronomicon Warrior

Pierce: Ranged Lane Creeps (normal and mega), Shadow Shaman’s Mass Serpent Ward, Venomancer’s Plague Ward, Beastmaster’s Boars, Brewmaster’s Earth and Storm Elements (Fire deals Hero damage), Undying’s Zombies, Necronomicon Archer, Dark Troll Summoner

Siege: Siege Creeps, Towers, the Fountain



Noteworthy examples of creeps, units, and spells that have an armor type other than “Hero”:

Weak: Beastmaster’s Hawks

Basic: Beastmaster’s Boars, Pugna’s Nether Ward, Templar Assassin’s Psionic Trap, Undying’s Tombstone

Strong: Roshan, Brewmaster’s Elements, Shadow Shaman’s Mass Serpent Ward, Venomancer’s Plague Ward, Enigma’s Eidolons, Nature’s Prophet’s Treants, Invoker’s Forged Spirits, Broodmother’s Spiderlings, Broodmother’s Spiderites, Lycan’s Wolves, Lone Druid’s Bear, Skeleton Warriors

Structure: Towers, Barracks, Siege Creeps, the Ancient

Soft: All Lane Creeps, Observer and Sentry Wards, Courier and Flying Courier, Juggernaut’s Healing Ward, Undying’s Zombies

(Note: This is not a complete list, these are only the units that I think it is likely that anyone might ever actually care about. Reference scripts/npc/npc_units.txt inside pak01_dir.vpk if you need to know any more than this.)

Defining Disables and Interrupts

There are many spells and abilities in DotA2 that interrupt, stun, silence, disable, banish, hex, or otherwise prevent heroes from taking actions. Using abilities such as these can prevent opponents from using Town Portal Scrolls to escape from combat or to stop powerful spells being channeled by the enemy. Transformation spells can never be interrupted. Knowing which abilities you can use to prevent enemy heroes from taking their desired actions is critical to success in DotA2. While it is often very clear when some spells stun or silence there are others that can be far less obvious. For this reason every spell or passive effect with the capacity to interrupt is included in each individual hero section for completeness.

There is no concept of diminishing returns in DotA2. Disables always last for their full duration unless they are removed a spell, a passive ability or death. If a disable overlaps with another disable of the same type then any time during that overlapping period is wasted for the purposes of keeping a unit disabled.

Stuns prevent units from moving, attacking, using items, or casting spells for a specific duration. Stuns interrupt cast animations, attack animations, and channeled spells/items.

Aside regarding “ministuns”: The concept often referred to as a “ministun” is somewhat misleading. The term implies that there is an alternate type of stun that has a very short specific duration. No such thing exists. There are very short stuns and very long stuns but they all function in the same way. There are several different spells and passive abilities with short stuns but these stuns do not have any specific duration in common. For the purposes of this guide and to avoid confusion I will not use the term “ministun” since the boundaries for such a thing would be arbitrary.

Interrupts stop cast animations, attack animations, and channeled spells/items.

Silences interrupt channeled spells and prevent units from casting spells for a specific duration. Silences prevent invisibility for any target currently in Fade Delay (targets that have already started fading in Fade Time will still become invisible). Silences do not interrupt channeled items or prevent heroes from using items.

Disables are similar to stuns, but they do not necessarily have a specific duration and instead cause the player to lose control of their unit(s) while the affected units are moved to or held in a position the player did not order. Some disables can be cancelled through the use of movement modifying abilities (like Pudge’s “Meat Hook” or Force Staff). Others can be canceled by interrupting enemy heroes. Disables interrupt cast animations, attack animations, and channeled spells/items.

Banishes temporarily remove units from the map at a specific location. Banishes interrupt cast animations, attack animations, and channeled spells/items.

Hexes reduce a unit’s base movement speed to 100 or 140 depending on which hex was used (boots and other items will make a hexed unit move faster than this - hexed units with Maximum Movement Speed will not be slowed) and prevent units from attacking, casting spells, or using items for a specific duration. Hexes disable evasion from every source and damage block from every source. Hexes disable the passive abilities of Gem of True Sight and Radiance. Hexes prevent invisibility for any target currently in Fade Delay (targets that have already started fading in Fade Time will still become invisible). Hexes interrupt cast animations, attack animations, and channeled spells/items. Gyrocopter’s “Rocket Barrage” is canceled by hexes.

Entangles prevent units from moving or attacking for a specific duration. Entangles interrupt cast animations, attack animations, and channeled spells/items. Since units can cast spells when entangled, any cast animation that is interrupted will be restarted once interrupted. Puck cannot “Phase Shift” when entangled. Nature’s Prophet cannot use “Teleportation” when entangled. Wisp’s “Relocate” is canceled and negated by entangles.

Ensnares are similar to entangles but they only prevent units from moving for a specific duration. Ensnares interrupt cast animations and channeled spells/items. Since units can cast spells when ensnared, any cast animation that is interrupted will be restarted once interrupted. Ensnared units cannot blink (Anti-Mage, Queen of Pain, Blink Dagger). Puck cannot “Phase Shift” when ensnared. Nature’s Prophet cannot use “Teleportation” when ensnared. Wisp’s “Relocate” is canceled and negated by ensnares.

Disarms prevent units from attacking and interrupt attack animations. Disarmed units can still move, cast spells, and use items. Disarms do not interrupt channeled items, channeled spells, or cast animations.

Taunts force units to attack a specific target. If a unit affected by a taunt was controlled by a player then this player will temporarily lose control of the unit. Any unit forced to attack another target because of a taunt effect will automatically move toward their target (if the target moves out of their attack range or wasn’t in their attack range to begin with) and attack. If a unit is taunted by two seperate units the taunted unit will only be affected by the taunt with the highest priority ("Duel" has priority over "Berserker's Call" and "Winter's Curse"). Units that are affected by taunts cannot cast spells or use items for the duration of the taunt. Taunts interrupt cast animations, attack animations, and channeled spells/items.

Stops prevent units from moving by setting a unit's movement speed to 0. Stops override the properties of maximum movement speed that would normally allow heroes to ignore movement speed altering effects. Stops do not disable blinks or teleports. Stops do not interrupt channeled items, channeled spells, or cast animations.

The Mechanics of Magic Resistance

Almost all heroes in DotA2 have a base magic resistance of 25%. The only two exceptions are Meepo with a base Magic Resistance of 35% and Visage with a base Magic Resistance of 10%. This means that Magical damage is reduced by the aforementioned percentages against all heroes.

Stacking Magic Resistances is possible, but the following rules are important to understand:

• All sources of Magic Resistances stack multiplicatively. This means that order in which they are applied does not matter, but that the effectiveness of a single ability or item that provides magic resistance is less noticeable the higher a hero's Magic Resistance is. This also means it is mathematically impossible to have 100% Magic Resistance.
  
  • Example: A hero with 25% Magic Resistance buys a Hood of Defiance. To calculate the hero's new Magic Resistance you must multiply the 75% damage that the hero is currently taking from Magical abilities by 30% and add the hero's current Magic Resistance (.75*.3 = 22.5% from Hood of Defiance + 25% base resistance = 47.5% total resistance). This means that the average hero purchasing Hood of Defiance is actually decreasing their incoming Magical damage by 22.5% (not 30%).
    
  • Example 2: Huskar is at 1% health and has “Berserker's Blood” at level 4. This means Huskar's Magic Resistance is increased by 98%. Huskar's base Magic Resistance is 25%. .75 * .98 = 73.5% from Berserker's Blood + 25% base resistance = 98.5% total resistance. Purchasing a Hood of Defiance would increase Huskar's Magic Resistance by .45% to 98.95%.
• Magical Damage Amplification is also calculated multiplicatively in the same way as Magical Resistance. To calculate total Magical Resistance after all modifications it is important to first calculate total Magical Resistance from base resistance, items, and abilities.
  
  • Example: Alchemist has 40% total Magical Resistance because he is standing within range 900 of an allied Rubick with level 4 “Null Field” (20% resistance (.75 * .2 = 15% actual resistance) from Null Field). An enemy Pugna and Skywrath Mage cast Decrepify and Ancient Seal on Alchemist (both of these spells are cast at level 4). Subtract Alchemist's total Magical Resistance from 100% (1 - .4 = .6) to find how much Magical damage he is currently taking, and multiply this number by any amplifications (.6 * 1.45 * 1.5 = 30.5% Magical Amplification).
• Only one “Ghost State” can ever decrease a hero's Magic Resistance. If a hero is affected by more than one “Ghost State” only the highest Magical Amplification is used to calculate a hero's Magic Resistance. The following “Ghost States” are available in DotA2:
  
  • Ghost Scepter's “Ghost Form”
    
  • Ethereal Blade's “Ether Blast”
    
  • Pugna's “Decrepify”

Structures do not have Magic Resistance, although most abilities that can damage structures do not deal full damage to structures.

• Dragon Knight's “Corrosive Breath” - Full Damage (20 per tick)
  
• Pugna's “Nether Blast” - 50% Damage Dealt
  
• Tiny's “Toss” - 33% Damage Dealt (Neither “Grow” nor “Aghanim's Scepter” change this value from 33% of the base “Toss” damage.)

The Limits of the System

DotA2 has many limits coded into its buffs, debuffs, and statistics that prevent heroes and units from going too far above or below certain thresholds. Approaching the boundaries of these limits allows you to destroy and outmaneuver your enemies in the most efficient ways. Ignoring these limits wastes your resources and gives your enemy the ability to capitalize on a potential unintended overcompensation.

The movement speed limit in DotA2 is 522. Any abilities or items that increase your movement speed by a flat amount or that increase your movement speed by a specific percentage can allow you to approach and stop at the 522 limit (Bloodseeker's "Thirst" passive ability allows him to break this limit - he can still be slowed since his movement speed is not ever actually set to the maximum). If you are faster than 522 with all items and abilities then the extra speed is wasted unless you are slowed. Any movement speed increase of this type can be reduced by a slowing effect. Some spells are flagged to disable any slowing effects by giving your hero "maximum movement speed". Some spells that move your hero break the speed limit of 522. Blinks, charges, jumps, and other effects frequently cause heroes to technically move faster than 522, but all such effects operate on their own special conditions. The following spells grant maximum movement speed:

• Centaur Warrunner's "Stampede"
  
• Dark Seer's "Surge"
  
• Lycan's "Shapeshift"
  
• Phantom Lancer's "Phantom Rush"
  
• Spirit Breaker's "Charge of Darkness"
  
• Weaver's "Shukuchi"
  
• Flying Courier's "Speed Burst"

The movement speed minimum in DotA2 is 100. No combination of slowing effects can ever reduce a hero below 100 movement speed. Overlapping slows are frequently wasting at least some slowing potential since the average hero’s movement speed in the mid-game is around 350 (any combined slows above 70-75% are almost entirely wasted on a hero without an ability that significantly increases their speed).

Exceptions:

• Disruptor's "Kinetic Field" can reduce a hero's movement speed below 100 when they are in contact with the barrier. (The UI will not show this.)
  
• Oracle's Fortune's End can reduce a hero's movement speed to 0.
  
• Slark's "Pounce" can reduce a hero's movement speed below 100 when they are at the end of their leash. (The UI will not show this.)

The attack speed limit in DotA2 is calculated by dividing a hero’s Base Attack Time (BAT) by 6. A hero can never attack any faster than 1/6th of its BAT. Almost all heroes in DotA2 have a BAT of 1.7. Most heroes cannot attack faster than 3.52 Attacks Per Second (APS), with a Minimum Attack Time (MAT) of .28.

Agility and attack speed items that increase a hero’s attack speed can only increase it until it hits the limit. Heroes with a BAT of 1.7 will hit this limit at 600 attack speed. If you are faster than 600 with all items and abilities then the extra speed is wasted unless you are slowed.

To find the maximum amount of usable attack speed for a given non-standard BAT you can perform the following equations and solve for X:

170 / Non-standard BAT = Y

Y + 500 = X

The following table shows all of the relevant attack speed information for heroes with a non-standard BAT:

Name	BAT	MAT	Max APS (rounded)	Max AS (rounded)
Alchemist Chemical Rage Level 1	1.4	.23	4.29	621.42
Alchemist Chemical Rage Level 2	1.2	.2	5	641.66
Alchemist Chemical Rage Level 3	1.0	.17	6	670
Anti-Mage	1.45	.24	4.14	617.24
Huskar	1.6	.27	3.75	606.25
Juggernaut	1.4	.23	4.29	621.42
Lone Druid True Form	1.6	.27	3.75	606.25
Morphling	1.6	.27	3.75	606.25
Oracle	1.4	.23	4.29	621.42
Queen of Pain	1.6	.27	3.75	606.25
Spirit Breaker	1.9	.32	3.16	589.47
Terrorblade	1.5	.25	4	613.33
Terrorblade Metamorphosis	1.6	.27	3.75	606.25
Treant Protector	1.9	.32	3.16	589.47
Troll Warlord Berserker's Rage	1.55	.26	3.87	609.67
Weaver	1.8	.3	3.33	594.44
Windranger	1.5	.25	4	613.33

The attack speed minimum in DotA2 is calculated by multiplying a hero’s BAT by 5. A hero can never attack any slower than 5x its BAT. Almost all heroes in DotA2 have a BAT of 1.7. This means that they can never attack any slower than 8.5 Seconds Per Attack. I have not calculated the attack speed minimums for heroes with a non-standard BAT since hitting these minimums (especially intentionally) is highly unlikely.

Armor has no limits in DotA2. You can have any amount of armor, no matter how high or how low. I only mention this because there were limits and minimums in Warcraft 3. The equation to calculate a hero’s physical damage reduction or amplification is (.06 * Armor) / (1 + .06 * |Armor|).

Statistics (STR, AGI, INT) cannot be reduced below 1 point by any spell or ability cast or applied by an enemy. There are many abilities and spells in DotA2 that allow you to steal, reduce, or alter statistics. None of these abilities can reduce a hero to 0 for any value. Exceptions:

• Morphling's "Morph" allows him to set a stat to 0 if that base stat is divisible by 2 (bonus stats from items are not calculated by "Morph").

The Mechanics of Evasion and Missing

Evasion in DotA2 is a passive ability that can cause physical attacks (right clicking on a target) to miss. If an attack misses it does no damage and the full attack animation is still played, wasting the attacker’s time and efforts. Blinding effects put a debuff on a target that causes their physical attacks to have a chance to miss targets as if their targets possessed evasion. You always have a 25% chance to miss any ranged attacks targeted at units on a higher level of terrain than yourself. Misses caused by terrain are most commonly seen in the river. Melee attacks automatically miss the target if the target is further than 350 units from the attacking unit's attack range. The chance to miss from terrain height, evasion, and blinding effects all stack (although not additively). Sources of evasion from items and abilities stack diminishingly multiplicatively. This means that one Butterfly provides 35% evasion, two Butterflies provide 57.75% evasion, three Butterflies provide 72.53% evasion, four Butterflies provide 82.14% evasion, five Butterflies provide 88.39% evasion, etc…

Heroes can never evade cleaves, spill damage, or splash damage if they were not the primary target of an attack with one of these properties. If any of these types of attacks miss a target because of evasion or miss chance then their area of effect damage will not be dealt to any other targets. Dragon Knight's "Elder Dragon Form" splash damage is dealt to enemies with a 50% reduction when he misses because of miss chance or evasion. Missing because of Faceless Void's "Backtrack" still deals full splash damage to surrounding enemies. Heroes can evade projectiles generated by attacks that hit multiple targets (such as Gyrocopter’s “Flak Cannon” or Medusa’s “Split Shot”).

Exceptions:

• Brewmaster will always evade one attack if he has not been attacked for 16/14/12/10 seconds with "Drunken Brawler".
  
• Doom's "Doom" with Aghanim's Scepter disables evasion.
  
• Faceless Void has a 10%/15%/20%/25% chance to dodge any type of attack OR spell with any type of damage except hp modification. This complex passive skill is the best type of damage avoidance in DotA2 (only Faceless Void has this). “Backtrack” stacks with evasion from items. Faceless Void can still dodge attacks from a hero using Monkey King Bar with “Backtrack”.
  
• Lion's "Hex" disables evasion.
  
• Scythe of Vyse's "Hex" disables evasion.
  
• Shadow Shaman's "Hex" disables evasion.
  
• Sniper’s “Headshot” passive skill negates evasion and miss chance, but only when this passive skill procs.
  
• Tusk’s “Walrus Punch” cannot miss due to evasion or miss chance.

Tactical Implications (When to buy Monkey King Bar):

• If more than one enemy hero from the following list is on the opposing team or if the enemy team is using evasion items (such as Butterfly, Heaven’s Halberd, or Talismans of Evasion) and you rely on your attacks for most of your damage (not spells - spells that deal physical damage cannot be evaded), you should strongly consider buying a Monkey King Bar since it negates all evasion and blinding effects.
  
• If the enemy team’s carry is heavily invested in evasion (whether through passive abilities or items) this can be reason enough to purchase a Monkey King Bar.
  
• Terrain miss chance plays a large role when attempting to siege tier 3 towers and will reduce a powerful ranged carry’s damage potential considerably. Monkey King Bar does not prevent misses when attacking towers, but it will still help against enemy heroes trying to benefit from the high ground advantage.

The following table is a compilation of all of the abilities and items that can cause you to miss a target. This table does not include the specific properties of the abilities, only their evasion or blinding chances. Any chances seperated by slashes in the table represent the increased chance to miss or evade based on the level of the spell.

Basic Invisibility Mechanics

It is very important when discussing invisibility in DotA2 to first establish that there is no established lexicon of terms to use when discussing invisibility in DotA2. Many websites will use the terms I am about to define interchangeably (often to draw incorrect conclusions) and therefore it is necessary to be very specific about the meanings of the following terms. I will be using the same terms that Valve uses in their ability data text files (scripts/npc/npc_abilities.txt and items.txt inside pak01_dir.vpk).

A unit is “fading out” when it is currently translucent but not yet totally invisible. If you have ever seen a Predator movie then you will be familiar with this visual effect. There is no excuse for not having seen at least 1 Predator movie. I refer to this game mechanic represented as a visual translucency phase as “Fade Time” in this guide. An opaque unit is never in Fade Time. Some units are opaque for a specific duration until they immediately disappear or begin a period of fade time. I refer to this game mechanic represented by an opaque phase as “Fade Delay” in this guide.

Units in Fade Time can attack, cast spells, and use items without losing or preventing invisibility as long as the attack point or cast point has been reached before the Fade Time ends (example: A hero’s attack point would have to be faster than .3 seconds to attack without losing invisibility with a Shadow Blade – a hero capable of attacking this fast would be able to benefit from Shadow Blade’s bonus damage twice).

Units in Fade Delay cannot attack, cast spells or use items without resetting the duration of the Fade Delay completely (Riki can cast spells and use items without resetting his Fade Delay).

Silencing a unit that is already translucent cannot prevent it from gaining invisibility because the fade has already begun. Silencing a unit before it is translucent will prevent it from becoming invisible with a spell or passive ability (for one of two different reasons). Heroes with items that grant invisibility can still use these items when silenced.

Stunning a unit will not prevent it from fading out if the prerequisites for fade out have already been met (examples: Broodmother in a web, Treant already cast Nature’s Guise, Riki not attacking).

Even if an invisible unit fades out (because its Fade Time ended) during a channeled disable spell that is currently holding it in place (such as Pudge’s “Dismember” or Bane’s “Fiend’s Grip”) the unit is still being affected and damaged by this spell normally (this is most commonly seen with Riki due to his “Permanent Invisibility”).

Invisibility Facts

• Any area of effect spell can hit invisible heroes. Exceptions:
  
  • Some spells seek targets in an area but do not hit invisible units if nothing is found when they seek. The following spells only seek visible targets:
    
    • Clockwerk’s “Battery Assault”
      
    • Death Prophet’s “Exorcism”
      
    • Ember Spirit's "Searing Chains"
      
    • Ember Spirit's "Sleight of Fist"
      
    • Gyrocopter’s “Rocket Barrage”
      
    • Gyrocopter’s “Flak Cannon”
      
    • Juggernaut’s “Omnislash”
      
    • Leshrac’s “Lightning Storm”
      
    • Lich’s “Chain Frost”
      
    • Luna’s “Moon Glaive”
      
    • Luna’s “Eclipse”
      
    • Medusa’s “Split Shot”
      
    • Medusa’s “Mystic Snake”
      
    • Mirana’s “Starstorm”
      
    • Razor’s “Eye of the Storm”
      
    • Rubick’s “Fade Bolt”
      
    • Shadow Shaman’s “Ether Shock”
      
    • Tinker’s “Heat-Seeking Missile”
      
    • Treant Protector’s “Overgrowth”
      
    • Undying’s “Tombstone”
      
    • Warlock’s “Fatal Bonds”
      
    • Witch Doctor’s “Paralyzing Cask”
      
    • Witch Doctor’s “Death Ward”
  • Abaddon’s “Aphotic Shield” cannot damage invisible units.
    
  • Meepo’s “Earthbind” cannot ensnare invisible units.
    
  • Techies' "Stasis Trap" will not detonate on invisible units, but it will stun them if they are in the radius when it is tripped.

• Cleave, spill, and splash damage do hit invisible units (examples: Kunkka’s “Tidebringer”, Templar Assassin’s “Psi Blades”, Dragon Knight’s “Elder Dragon Form” and Shadow Shaman’s “Mass Serpent Ward”).
  
• Invisible units that cannot move are not detected by Dust of Appearance. This includes Observer Wards, Sentry Wards, Psionic Traps, Stasis Traps, Land Mines, and Remote Mines.
  
• Units that gain invisibility (whose Fade Delay and Fade Time have ended and are not currently visible due to shared vision or invisibility detecting skills/items) while a projectile (spell or attack) is in flight will not be damaged or affected by the projectile unless the projectile is a spell that cannot be negated. Projectiles that cannot be negated are noted as such in the hero sections. Exceptions:
  
  • Medusa – Mystic Snake: This spell will not damage or steal mana from invisible units.
    
  • Sniper – Assassinate: This spell will damage and interrupt invisible units normally since it provides True Sight (it can be negated with any other method - jump, blink, transformation, etc...).
• All root effects (whether magical or physical / entangle or ensnare) prevent invisible units from fading out. Despite this, even area of effect root spells cannot reveal (or even entangle/ensnare) currently invisible units. The following spells or passive abilities have root effects:
  
  • Crystal Maiden – Frostbite
    
  • Ember Spirit – Searing Chains
    
  • Lone Druid (Spirit Bear) – Entangling Claws
    
  • Meepo – Earthbind
    
  • Naga Siren – Ensnare
    
  • Treant Protector – Overgrowth
• Casting spells does not break invisibility until a given spell’s cast point is reached. This means that spells with a long cast animation and an equally long cast point will not break invisibility until the effect of the spell has occurred (example: Nature’s Prophet can cast “Teleportation” while invisible and will only be revealed when he arrives at his target destination). Note that some spells do have considerable delay before any effect occurs (such as Pugna’s “Nether Blast”). Exception:
  
  • Shadow Fiend’s “Requiem of Souls”: This spell will reveal Shadow Fiend after 1 second of the 1.7 seconds required to cast this spell (Shadow Fiend’s cast animation happens after the front-loaded 1 second animation required for this spell).
• Almost all auras (positive or negative) remain visible in the buff bar when an enemy hero is invisible. Exceptions:
  
  • Shadow Fiend’s “Presence of the Dark Lord” is hidden and completely disabled when he is invisible. It provides no benefits if the enemy cannot see Shadow Fiend.
    
  • Necrophos’s “Heartstopper Aura” is hidden but fully effective when he is not visible for any reason (including invisibility). The enemy will continue to take full damage from this passive ability, but its icon will not appear on the buff bar.
    
  • Assault Cuirass's “Assault Aura” is hidden but fully effective when the carrier is not visible for any reason (including invisibility). The enemy will have their armor reduced in the stat pane, but its icon will not appear on the buff bar.
    
  • Shiva's Guard's “Freezing Aura” is hidden but fully effective when the carrier is not visible for any reason (including invisibility). The enemy will have their attack speed reduced in the stat pane, but its icon will not appear on the buff bar.
• Invisible enemy heroes with an active Radiance will apply the “Burn Damage” debuff even when they are invisible. The particle effect associated with burn damage can be used to pinpoint the location of an invisible enemy hero with an active Radiance because the fiery particles generated by this debuff act as a windsock, visually blowing away from the direction of the Radiance holder’s position in real time. Damaging or disabling enemy heroes with ground targeted abilities is considerably easier when you’re certain of their direction in relation to your hero.
  
• Some heroes have an alternate set of aggressive stance animations whenever an enemy unit is nearby. These animations are not used when an invisible enemy hero is nearby, but they ARE used when an invisible enemy hero is nearby that the aggressive-stance hero has vision of through some means of detection. Invisible heroes can use this information to their advantage to locate Sentry Wards or identify Gem of True Sight carriers quickly. Some aggressive stances are much harder to identify than others. The following heroes have an alternate aggressive stance:
  
  • Abaddon
    
  • Alchemist
    
  • Brewmaster
    
  • Bristleback
    
  • Earth Spirit
    
  • Ember Spirit
    
  • Huskar
    
  • Juggernaut
    
  • Lifestealer
    
  • Medusa
    
  • Skywrath Mage
    
  • Sniper

The following Heroes have access to some form of invisibility (for themselves or units they control):

• Beastmaster
  
• Bounty Hunter
  
• Brewmaster
  
• Broodmother
  
• Clinkz
  
• Invoker
  
• Lycan
  
• Mirana
  
• Nyx Assassin
  
• Oracle
  
• Riki
  
• Sand King
  
• Slark
  
• Techies
  
• Templar Assassin
  
• Treant Protector
  
• Weaver

Information regarding the invisibility duration, fade time, fade delay, interaction with silence, phasing rules and other miscellaneous notes can be found in individual hero sections. I have also included what I believe to be the best counters to each hero's invisibility. Unlike most information in this guide, these are my opinions, not facts. Noteworthy counters to invisibility are listed as such in individual hero sections.

The Mechanics of Vision

Vision in DotA2 is very similar to vision in RTS games. Heroes, units and structures provide vision in a circular area centered on them. Most heroes in DotA2 can see range 1800 during the day and range 800 at night. I have bolded any deviations from these ranges. There are three main types of vision in DotA2:

Ground vision is the type of that most units possess. Ground vision cannot see through trees or onto higher elevations. Ground vision cannot see into the Roshan pit. Many heroes can summon units that provide Ground vision. These units are not listed here since this is extremely common.

Flying vision can see everything within its radius. Flying vision can see through trees and onto higher ground. Flying vision can see into the Roshan pit.

Shared vision provides the vision radius of a unit to the other team. Shared vision copies the properties of the type of vision the affected unit possesses (shared vision of a unit with Flying vision will grant Flying vision). Shared vision will only reveal what could actually be seen if the unit affected by it were on the team of the unit that caused the vision to be shared (meaning it will not reveal the positions of other enemy units unless they are within the vision range of the units who’s vision is shared).

Fogged vision provides vision of enemy heroes in the fog of war. This rare type of vision does not have an official name at this time. Enemy heroes revealed by Fogged vision can be selected normally, allowing their items to be checked and their health and mana bars revealed. No other information can be obtained from a unit that is affected by Fogged vision.

True Sight is not a vision type, but a property of vision types that reveals invisible units. True Sight can be granted on a single targeted unit or in an area.

As with all things in DotA2, there are many exceptions to the aforementioned rules. Heroes with unique vision ranges and spells that provide vision are detailed in the hero sections.

The Mechanics of Denies

Any faction allied hero, creep, or structure (except the Ancient) that can take damage in DotA2 can be denied under specific conditions. Neutral creeps cannot be denied unless they are converted with a spell. The following hit point thresholds must be reached for these types to be destroyed:

Heroes – 25%
Creeps – 50%
Structures – 10%

Denying Heroes:

Heroes can only be denied when they are affected by specific spells. The following spells allow any hero that is currently affected by them to be denied:

• Doom’s “Doom”
  
• Phoenix's "Supernova" (the "Supernova" counts as a creep for the purposes of denies)
  
• Queen of Pain’s “Shadow Strike”
  
• Venomancer’s “Venomous Gale”

Some spells allow heroes to deny themselves or their team mates. The following spells allow heroes to deny themselves or others without any enemy action:

• Abaddon’s “Mist Coil”
  
• Alchemist’s “Unstable Concoction”
  
• Bane’s “Nightmare”
  
• Pudge’s “Rot”
  
• Pugna’s “Life Drain”
  
• Techies' "Suicide Squad, Attack!"

Bloodstone's active ability "Pocket Deny" allows any hero to deny themselves.

Denied heroes grant 0 experience and 0 assist gold.

Denying Creeps:

Any faction allied creep can be denied when it is below 50% hit points for 50% of its normal experience. Lane creeps provide experience when denied to enemy heroes within range 1300. Lane creeps always provide the exact same amount of experience to heroes, no matter what type of creep they are or how much experience they would normally provide if they had not been denied.

Converted neutral creeps are always worth 0 experience when denied. Most summoned units are worth 0 experience when denied. The following summoned units are worth 50% of their normal experience when denied:

• Gyrocopter's "Homing Missile"
  
• Techies' "Land Mines"
  
• Techies' "Stasis Trap"
  
• Techies' "Remote Mines"
  
• Templar Assassin's "Psionic Trap"
  
• Venomancer's "Plague Ward"
  
• Weaver's "The Swarm"

Denying Structures:

Any structure that can be destroyed (except the Ancient) can be denied when it is below 10% hit points. Structures provide experience when denied to enemy heroes within range 1300. Structures provide 36 experience when denied and follow all of the same rules (experience is split among heroes, etc…) that creeps follow when denied (this means that all structures are worth more experience when denied than when they are destroyed normally).

Towers denies provide some gold. Each tier of tower provides a different default amount of gold to enemy heroes anywhere on the map (including dead) when denied. The deny gold values are as follows (multiply by 5 to get the total gold provided to the enemy heroes):

• Tier 1 – 80 gold
  
• Tier 2 – 100 gold
  
• Tier 3 – 120 gold
  
• Tier 4 – 140 gold

[/b]
[/list]

When an enemy barracks is denied it will provide the same amount of gold that it would have provided had it been destroyed normally (275 for melee and 225 for ranged - there is no good reason to deny your own barracks).

The Mechanics of Purges

There are many different types of purges in DotA2 with several different effects associated with them. Some purges are definitely superior to others, but the specifics of each can be quite complex. Most debuffs in DotA2 can be purged. Most buffs in DotA2 cannot be purged. Gaining Spell Immunity purges effects on heroes in the same fashion as other purge effects (with the noteworthy exception of “special” purges). There are a multitude of exceptions to these statements, but the following statements are always true:

• Toggled spells cannot be purged.
  
• Persistent Auras cannot be purged.
  
• Passive and No Target invisibility spells and abilities cannot be purged.
  
• Double Damage, Haste, Invisibility, and Regeneration Runes can be purged. Some purges will destroy illusions created by Illusion Runes. Regeneration Rune is not purged by gaining Spell Immunity. Double Damage, Haste, and Invisibility Runes are purged by gaining Spell Immunity.
  
• Transformations cannot be purged (spells that alter the visual model of a hero – spells that alter their model scale and particle effects often can be purged).
  
• Taunts cannot be purged.
  
• Stuns and disables cannot be purged (with the exception of some “special” purges).
  
• Allied purges do not remove allied buffs.
  
• Allied Spell Immunity does not remove allied buffs.

The following hero spells and abilities have a purging effect or grant Spell Immunity:

• Abaddon's "Aphotic Shield"
  
• Abaddon's "Borrowed Time"
  
• Brewmaster’s “Spell Immunity” (Brewmaster is displaced when “Primal Split” begins and ends)
  
• Brewmaster’s “Dispel Magic”
  
• Chaos Knight’s “Phantasm” (this spell displaces)
  
• Doom's "Doom"
  
• Invoker’s “Tornado”
  
• Juggernaut’s “Blade Fury”
  
• Legion Commander's "Press the Attack"

• Slark’s “Dark Pact”
  
• Tidehunter’s “Kraken Shell”
  
• Visage's "Summon Familiars"
  
• Weaver’s “Time Lapse”

The following item abilities have a purging effect or grant Spell Immunity:

• Black King Bar’s “Avatar”
  
• Diffusal Blade’s “Purge”
  
• Eul’s Scepter of Divinity’s “Cyclone”
  
• Manta Style’s “Mirror Image” (this ability displaces)

There are seven “special” purges in DotA2 that purge some effects that cannot normally be purged. These seven special purges are not mechanically identical, but they share enough commonality that they can generally be discussed as a subset of purges. Some of these purges can have very complex interactions with other abilities that are discussed in the hero sections in further detail. The seven special purges in DotA2 are:

• Abaddon’s “Aphotic Shield”
  
• Abaddon’s “Borrowed Time”
  
• Legion Commander's "Press the Attack"
  
• Oracle's "Fortune's End"
  
• Slark’s “Dark Pact”
  
• Tidehunter’s “Kraken Shell”
  
• Weaver’s “Time Lapse”

Hero Abilities That Create Illusions

Illusions are a type of summoned unit that mimic heroes. Illusions are normally controlled by the player that creates them. Most illusions are visually indistinguishable from the hero that they mimic. Illusions can never use spells, but they do benefit from some passive abilities. Several passive abilities that illusions do not benefit from create effects or animations to mimic these abilities. The fact that an animation or effect is displayed by an illusion does not mean that the illusion actually benefits from the corresponding passive ability. The source of an illusion determines how much damage it takes and how much damage it deals, with the exception that illusions always deal 25% less damage to structures. The following spells and items can create illusions:


Chaos Knight – Phantasm:
Outgoing Damage Multiplier: 1x
Incoming Damage Multiplier: 2x
Number of Illusions: 1/2/3 (at levels 1/2/3 respectively) with a 50% chance to create a bonus illusion.
Duration of Illusions: 42 seconds
Notes:

• Chaos Knight is invulnerable for .5 seconds while casting this spell.
  
• This spell purges some negative debuffs on Chaos Knight.

Dark Seer – Wall of Replica:
Outgoing Damage Multiplier: .7x/.8x/.9x (at levels 1/2/3 respectively) or 1x/1.2x/1.4x with Aghanim’s Scepter (at levels 1/2/3 respectively)
Incoming Damage Multiplier: 4x
Number of Illusions: One illusion for each enemy hero that pass through the wall.
Duration of Illusions: 15/30/45 seconds (at levels 1/2/3 respectively)
Notes:

• More than one illusion will not be created if more than one Meepo crosses the wall. The first clone or Meepo prime will be dealt the damage and replicated, but any additional Meepos will not (assuming the illusion is still alive as would be the case for any other hero).
  
• Illusions created by “Wall of Replica” do not attempt to visually mimic the hero that their stats are based on. “Wall of Replica” illusions have a special texture that indicates to enemy players that they are not real.

Morphling – Replicate:
Outgoing Damage Multiplier: .5x
Incoming Damage Multiplier: 1x
Number of Illusions: 1
Duration of Illusions: 30/45/60 seconds (at levels 1/2/3 respectively)
Note:

• Morphling can use “Replicate” to create illusions of Spell Immune allied or enemy heroes.
  
• Morphling cannot use “Replicate” on any illusion of himself that he controls (Manta Style, Illusion Rune). Morphling can use “Replicate” on illusions of himself that he does not control (Shadow Demon’s “Disruption”, Dark Seer’s “Wall of Replica”).

Incoming Damage Multiplier: 6x/5x/4x/3x (at levels 1/2/3/4 respectively)
Number of Illusions: 3
Duration of Illusions: 30 seconds
Notes:

• Naga Siren is invulnerable for .3 seconds while casting this spell.

Notes:

• Illusions are created for invisible heroes and will follow their position.
  
• Illusions created by “Haunt” cannot be controlled.
  
• Illusions created by "Haunt" are destroyed when Spectre uses "Reality" on them, meaning that Spectre's total damage output when using "Haunt" is likely to be diminished by using "Reality" repeatedly, unless she is using "Reality" to move away from a dead enemy hero.
  
• “Haunt” illusions will not attack for 1 second after they are created.

The Mechanics of Roshan

The following section is dedicated to telling you everything Roshan doesn’t want you to know (about killing him). Concepts are ordered by my opinion of their importance and relevance to the topic of killing a giant man, err – dragon man, err – maybe he’s just a dragon?

Base Stats:
Health: 7500
Health Regen: 20 per second
Armor: 4
Magic Resistance: 75%
Attack Damage: 65
BAT: 1.0
Move Speed: 270
Vision Radius: 1400
Attack Range: 128
Turn Rate: 1.0

The most effective way to kill Roshan is by reducing his armor value. Since Roshan has such a high natural magical resistance the vast majority of damage dealt to him will be through auto attacks. Any spell or item that can reduce armor (even by only a few points) will greatly reduce the time required to kill Roshan.

Roshan is almost entirely impervious to damage from magical abilities due to his 75% magical resistance. The vast majority of spells and abilities in DotA2 are magical, but those that deal physical and pure type damage will still be effective. Implications:

• Spells and abilities that add pure damage to auto attacks (like Silencer’s “Glaives of Wisdom” and Outworld Devourer’s “Arcane Orb”) are very effective against Roshan due to their damage type.
  
• Spells and abilities that amplify magical damage are not very effective against Roshan because they only act as multipliers on the already very low 25% damage you will deal.
  
  • Example (assuming that Roshan’s “Spell Shield” is on cooldown): Pugna casts “Decrepify” on Roshan, then Pugna uses Veil of Discord’s “Magic Weakness” on Roshan, and finally Lina casts “Laguna Blade” on Roshan at level 16. Even with massive magical damage amplification, “Laguna Blade” only deals 445.31 magical damage (less than half its normal 950 damage). First “Laguna Blade” is reduced to 237.5 by Roshan’s 75% resistance, then it is amplified by 118.75 to 356.25 by “Decrepify”, and finally it is amplified by 89.06 to 445.31 by Veil of Discord.

Roshan provides 1789 experience and 200 gold when killed. The experience is awarded to all heroes on the team that successfully kills Roshan within experience range (1300). The 200 gold is awarded to all heroes on the team that successfully kills Roshan globally. The hero that last hits Roshan will gain an additional 150-400 gold (rolled randomly). Roshan drops the Aegis of the Immortal every time he dies. He drops Cheese every death after his second death. Implications:

• Split 5 ways, killing Roshan at level 1 will bring all attending heroes to level 2. Killing Roshan at level 1 alone will power-level a hero to level 5.
  
• The 200 gold gained from killing Roshan is reliable, but the randomized last hit gold is not.
  
• The team that gets the reliable gold and experience is entirely dependent on who gets the last hit on Roshan. Dealing 99.9% of the damage is not sufficient.
  
• Attacking the Aegis of the Immortal or the Cheese can deny these items to your enemies. The following heroes and items can be used to deny items on the ground without losing invisibility:
  
  • Bounty Hunter using “Shadow Walk”
    
  • Nyx Assassin using “Vendetta”
    
  • Shadow Blade

Roshan grows more powerful over time. From the 0:00 mark, Roshan will gain 500 max hit points, +10 damage and +.5 armor every 4 minutes when the day/night cycle changes. Roshan will grow stronger in this way indefinitely. Implications:

• Roshan does not gain actual hit points when he grows stronger; he gains a higher maximum hit point value. He will have to regenerate the missing hit points at his normal rate (20 hp per second). If he grows stronger during a fight, he will benefit from the damage and armor immediately, but the higher maximum hit points will not help him in any way.
  
• Roshan’s effective hit points do not scale in a linear fashion as the game progresses. A hero attempting to kill Roshan with physical damage (read: most heroes) should attempt to do so as soon as possible.

Any illusion that attacks Roshan is destroyed. While illusions are destroyed by attacking Roshan, their attack damage is still dealt to him before they are destroyed (making it possible, but improbable, to steal Roshan with an illusion). Illusions can be used to absorb Roshan’s damage by selecting them and issuing a move command on Roshan. Roshan will then prioritize the illusions, allowing the heroes to attack Roshan with impunity for a time.

Roshan is phased. It is not possible to body block Roshan with any units or heroes. This prevents him from being exploited with stationary units and some special hero abilities. This also allows heroes to move inside Roshan while attacking him, forcing him to attack them since they will become his closest target.

Roshan cannot be attacked outside of his pit. When attempting to pull him outside of the pit keep in mind that your attack commands will not have any effect if they are ordered against him. Entangling him or otherwise holding him outside of the pit has very little value for this reason.

Roshan's Spells and Abilities

Roshan has the following powerful spells and abilities:

• Spell Block – Roshan effectively has a Linken’s Sphere on a 15 second cooldown (except he’s also Roshan, so many of the spells that might trigger a Linken’s Sphere might not even be able to be cast on Roshan). Notes:
  
  • Roshan’s "Spell Block" should be broken with a low mana cost spell or item if necessary. However, there is usually very little reason to trigger Roshan’s “Spell Block” since most abilities have so little effect on him. Triggering “Spell Block” (without any real strategy behind doing so) may even allow the enemy team to deal the killing blow to Roshan if they attempt to snipe his final hit points with a very high damage spell.
    
  • Roshan is treated as an ancient creep for the purposes of most spells that cannot target ancient creeps.
    
  • Some spells and passive abilities have absolutely no effect on Roshan at all, even though they can be cast on him normally and may even appear to apply debuffs to him. See the list of effective spells later in the guide for more information.
• Bash – Roshan has a 15% chance to stun for 1.65 seconds and deal 50 bonus physical damage when he attacks. Notes:
  
  • Roshan’s bashes can drastically reduce the damage output of a single hero. Whenever multiple heroes attempt to kill Roshan, the most durable hero with the lowest damage per second should use a move command on Roshan (this will move that hero to point blank range). Roshan will then prioritize this target, allowing the hero that is dealing the most damage to continue to do so (uninterrupted by bashes). Any type of summon or dominated neutral can also be used in this way to almost entirely negate Roshan's damage output against heroes.
    
  • Roshan’s bash does affect Spell Immune units.
• Slam – Roshan casts a 70 magical damage range 350 area of effect slow that reduces attack speed and movement speed by 50% for 2 seconds on heroes and 4 seconds on non-heroes when 3 or more units move within range of the spell. Notes:
  
  • This spell's damage increases by 20 every 4 minutes
    
  • Unless there are three melee heroes on your team there is no almost no good reason for this spell to be triggered. Ranged heroes moving too close to Roshan cause this spell to be triggered all too often and slow their team’s efforts to kill Roshan.
    
  • This spell does not cost mana (Roshan does not have mana), so causing him to cast it only puts it on a 10 second cooldown.

Spells and Abilities to use Against Roshan

• Visage’s Familiars

Roshan is heavy. Roshan cannot be lifted into the air or repositioned by any spell or effect. This means that several spells that lift and push units and heroes are completely wasted against him (the mana is spent and the cooldown begins, but there is no effect). The following spells are totally wasted against Roshan because of his weight:

• Batrider’s “Flaming Lasso”
  
• Brewmaster’s “Cyclone”
  
• Chaos Knight’s “Reality Rift” (Roshan won’t be moved, but Chaos Knight will be)
  
• Dark Seer’s “Vacuum”
  
• Eul’s Scepter’s “Cyclone”
  
• Force Staff’s “Force”
  
• Invoker’s “Tornado”
  
• Invoker’s “Deafening Blast”
  
• Keeper of the Light’s “Blinding Light”
  
• Kunkka’s “Torrent”
  
• Lion’s “Earth Spike”
  
• Magnus’s “Skewer”
  
• Nyx Assassin’s “Impale”
  
• Pudge’s “Meat Hook”
  
• Spirit Breaker’s “Greater Bash”

The following abilities will not push or lift Roshan, but they will still stun him:

• Batrider’s “Flamebreak”
  
• Rubick’s “Telekinesis”
  
• Sand King’s “Burrowstrike”
  
• Tusk’s “Walrus Punch”

Situationally Useful Anti-Roshan Spells

The following spells might be used in some situations against Roshan:

• Bane’s “Nightmare” – This spell affects Roshan in exactly the same way that it affects players. The only difference is that Roshan is too smart to attack an enemy affected by this spell.
  
• Death Prophet’s “Exorcism” – Death Prophet’s ghosts will target Roshan normally, meaning that this spell can be used to kill him very quickly in a pinch.
  
• Naga Siren’s “Song of the Siren” – This spell has no effect against Roshan what so ever. Of course, this is exactly the point.
  
• Night Stalker’s “Crippling Fear” – This spell is far less useful against Roshan during the day and the mana might be spent better elsewhere.
  
• Oracle's "False Promise" – This spell will allow a single hero to attack Roshan for several seconds with impunity. Roshan cannot attack the invisible hero, but he will attack anyone else in the pit, so this is only useful if you have a powerful carry soloing Roshan.
  
• Pudge’s “Dismember” – This spell will disable Roshan for 6 seconds, but it will also be heard globally by the enemy, potentially giving away your Roshan attempt.
  
• Pugna’s “Decrepify” – Using this spell on Roshan is almost always a bad idea for aforementioned reasons, but it might be used in rare situations to secure the last hit on Roshan when the enemy team is closeby.
  
• Shadow Shaman’s “Mass Serpent Ward” – The wards do attack Roshan normally. It may be worth using the wards to kill him more quickly if you don't have enough damage to do so in a reasonable amount of time.
  
• Undying’s “Flesh Golem” – The damage amplification aura affects Roshan normally, meaning that this spell can be used to kill him very quickly in a pinch.
  
• Viper’s “Viper Strike” – This spell could be used against Roshan to reduce attack speed if an ally is at risk of dying to Roshan or if Viper has an Aghanim’s Scepter.
  
• Windranger’s “Windrun” – This spell can be used to negate Roshan’s damage if another hero is not available to do so.

Table of Important Events

The following table contains a list of important events that occur at specific times during the first hour of a DotA2 match. The Day/Night cycle and the creep upgrades will continue far beyond the first hour, but this table is intended to be used a reference for these events, not a deep look at their mechanics.

Time:	Event:	Notes:
-1:30	Roshan Spawns in every mode except All Pick
-1:15	Roshan Spawns in All Pick
0:00	First Rune Spawns	Runes spawn on every even numbered minute for the rest of the game.

Priorities of Unique Attack Modifiers

Unique Attack Modifiers (or UAMs) are a category of special effects associated with specific hero and item abilities. A single attack cannot normally benefit from more than one UAM, although there are a few exceptions to this rule. Equipping a hero with more than one UAM is usually a very poor choice. UAMs have established priorities in the event that a hero has access to more than one UAM at the same time. I have labeled UAMs with a tiered system. Lower numbered tiers trump higher numbered tiers.

Tier 1:

All effects provided by UAMs in this Tier are able to override other UAMs when their chance-based condition occurs. This means that Tier 1 UAMs can be used alongside Tier 2 and Tier 3 UAMs without losing much of the potential provided by Tier 2 and Tier 3 UAMs. It is not possible for more than one Tier 1 UAM to occur on a single attack. If a unit has access to more than one Tier 1 UAM then items will be checked before passive abilities.

• Maelstrom
  
• Mjollnir

Tier 2:

Hero Abilities override Tier 3 UAMs automatically. If a hero ability is cast manually (auto-cast disabled) it will also override any Tier 1 UAM. Passive Tier 2 UAMs that cannot be disabled will always override Tier 3 UAMs. The only way to prevent conflict between passive Tier 2 UAMs and Tier 3 UAMs is to intentionally never spend skill points on these passive abilities.

• Anti-Mage’s “Mana Break”
  
• Broodmother’s “Incapacitating Bite”
  
• Drow Ranger’s “Frost Arrows”
  
• Enchantress’s “Impetus”
  
• Jakiro’s “Liquid Fire”
  
• Outworld Devourer’s “Arcane Orb”
  
• Sand King’s “Caustic Finale”
  
• Silencer’s “Glaives of Wisdom”
  
• Viper’s “Poison Attack”

Tier 3:

The priority of all remaining item-based UAMs is based on the order in which they were acquired (the inventory slot they are in is not relevant). A hero can switch the priority of their UAMs in this tier by dropping the UAM with the highest priority. The second most recently acquired UAM will now have the highest priority. Picking up the dropped item will not revert the priority (the item that was dropped now has the lowest priority).

• Desolator’s “Corruption”
  
• Eye of Skadi’s “Cold Attack” (works with any UAM that provides Lifesteal)
  
• Helm of the Dominator’s “Lifesteal”
  
• Mask of Madness’s “Lifesteal”
  
• Morbid Mask’s “Lifesteal”
  
• Orb of Venom’s “Poison Attack” (works with any UAM that provides Lifesteal)
  
• Satanic’s “Lifesteal”

The Mechanics of Friendly Fire

When attempting to deny friendly heroes or when forced to attack an ally by "Winter's Curse" some offensive procs and defensive procs can occur. As with many things in DotA2, there are rules to these interactions and the while I have made notes on some of the more common rules, a lot of these will probably feel very arbitrary. I have organized these rules into 4 tables. Offensive effects would only be able to occur when the hero or item in question is used to attack an ally. Defensive effects would only be able to occur when the hero or item in question is attacked by an ally.

How to use the Hero Sections

The hero sections of this guide are not comprehensive collections of data regarding DotA2's heroes. The hero sections are intended to tell you everything you might not have learned about a hero from reading the in-game tooltips or playing the hero. While some of the data in the hero sections may be repeated in the tooltips, I have attempted to only include such information when the specifics of a spell are crucial to understand or when a property of a spell is extremely important.

The rules of damage types, immunities, evasion, invisibility, disables and resistances such as those described in the previous sections are sacred in DotA2 and are never broken, except in the wide variety of circumstances in which they are broken. I have mentioned many spells in the following sections that can affect Spell Immune units. Some of them do not mention that they can be cast on Spell Immune units. This exclusion is intentional, since some of them may be able to affect Spell Immune units but are unable to target them directly. I have explicitly stated when an area of effect spell can affect Spell Immune units. I have also noted in many spell descriptions that certain buffs or debuffs cannot be dispelled by allied purges or allied Spell Immunity. Every spell noted in this way can be purged by the enemy or dispelled with enemy Spell Immunity. Any spell that causes a transformation cannot be purged. All No Target and Passive invisibility spells cannot be purged. Every other spell that includes a buff or debuff that is not mentioned here can be purged or removed with Spell Immunity by the enemy.

Every spell or passive ability that damages structures, grants invulnerability, destroys illusions, negates projectiles, cannot be negated with blink/jump/transformation, grants maximum movement speed, heals Spell Immune units, negates damage block, targets/damages siege creeps, affects couriers, purges, destroys trees, can be cast without interrupting channels, allows heroes to be denied or just has weird special rules is listed here as well.

I have rated the importance of understanding the following rules with a numeric tiered system (since Steam Guides do not currently support colored text). These tiers are completely based on my opinion of the threat a spell poses and how surprised a player might be when it doesn't follow the rules that they might expect it to have adhered to. Tier 1 spells are very important to understand, regardless of whether you play that hero or not (either because of their potential lethality or their degree of deviance from the rules). If you do not understand the Tier 1 spells they will kill you or someone you love. Tier 2 spells are important to understand for anyone that ever plays that hero. Knowing Tier 2 spells will also provide an advantage against this hero. Tier 3 spells are only important to understand if you want to have a comprehensive understanding of a hero. Especially important key words in the document are bold to ensure that you notice their especial importance.

• This spell cannot negate taunts.

Alchemist – Acid Spray (physical) Tier 1:

• Every effect of this spell affects Spell Immune units.

• This spell has a .35 second transformation time. Some projectiles can be negated if the transformation is timed correctly. The cast/attack animation for the projectile must have ended for this spell to negate it successfully (meaning the projectile will be in flight).

• This spell provides flying vision.

Anti-Mage

Anti-Mage – Blink (does not have a damage type) Tier 2:

• Anti-Mage can negate some projectiles with the blink effect of “Blink”. The cast/attack animation for the projectile must have ended for this spell to dodge successfully (meaning the projectile will be in flight).

Anti-Mage – Mana Void (magical) Tier 1:

• This spell is a stun.
  
• The stun effect of this spell does affect Spell Immune units. Even though a Spell Immune target of this spell will not be damaged by it, Spell Immunity on the target does not prevent other enemies within this spell’s area of effect from taking damage because of missing mana on the primary target.

• Couriers are stunned by this spell.

Axe (Mogul Khan)

Axe – Berserker’s Call (does not have a damage type) Tier 1:

• Every effect of this spell affects Spell Immune units.
  
• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).

If either hero taunted a unit that was already taunted then their taunt will apply to the taunted unit when the first taunt debuff ends if the two taunts did not overlap in duration entirely.
  
• This spell is a noteworthy invisibility counter. "Berserker’s Call" does force invisible units to attack Axe. In the rare even that this does not remove the unit’s invisibility "Berserker’s Call" will at least hold it in a known location.

Axe – Counter Helix (physical) Tier 1:

• Every effect of this passive ability affects Spell Immune units.
  
• This passive ability can damage siege creeps.

Axe – Culling Blade (magical if non-lethal, physical if lethal) Tier 1:

• The speed buff granted by making a successful kill with this spell cannot be dispelled with Spell Immunity or any type of allied purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• This spell does magical damage if it fails to kill the target. If the target is within the lethal hit point threshold the damage is applied as physical. The killing blow ignores Spell Immunity (since the damage is not magical).
  
• This spell can be cast on Spell Immune units.
  
• Units below the health threshold are killed instantly, even killing units that cannot normally be killed with physical damage, such as units affected by Abaddon's "Borrowed Time", Dazzle’s “Shallow Grave”, Nyx Assassin’s “Spiked Carapace”, Omniknight’s “Guardian Angel”, or Templar Assassin’s “Refraction”. Faceless Void cannot "Backtrack" this spell. All status effects are removed before the damage is dealt.
  
• Couriers are killed by this spell.
  
• CHOP!

Bane (Atropos)

Bane – Enfeeble (does not have a damage type) Tier 2:

• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).

Bane – Nightmare (pure) Tier 1:

• This spell is a disable.
  
• During the first second of the “Nightmare” the target of the spell is invulnerable (since Bane can choose to awaken himself from “Nightmare” at any time this can be used to negate powerful spells or attacks without suffering from much pure damage).
  
• Bane can use this spell to deny allies.
  
• This spell will end and the target will be freed if the target receives any type of damage from a spell (other than hp modification). Exception:
  
  • Ember Spirit's "Sleight of Fist"
• If another player (of either team) attempts to attack the target of this spell the “Nightmare” is transferred to them.
  
• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…), but the "Nightmare" cannot be transferred to Spell Immune units.

Bane – Fiend’s Grip (magical) Tier 1:

• This spell is a disable.
  
• The disable and mana draining effects of this spell do affect Spell Immune units.
  
• This spell can be cast on Spell Immune units.

• This spell's debuff stacks.
  
• This spell's bonus damage is halved when applied to creeps.
  
• All damage from Batrider's attacks, items and spells is amplified, except for damage from the following items:
  
  • Eul's Scepter of Divinity
    
  • Orb of Venom
    
  • Urn of Shadows

• The stun effect of this spell does affect Spell Immune units. The additional effects of this spell do not ignore Spell Immunity.
  
• This spell can be cast on Spell Immune units.
  
• Couriers are stunned by this spell.

Invisibility:

Hawk (Invisibility):

Duration: 60 Seconds (hawk lifespan)

Fade Time: 1 Second (this skill only exists at levels 3 & 4)

Fade Delay: 3 Seconds (this skill only exists at levels 3 & 4)

Can be revealed by silence: No

Can phase through other units: Flying units do not collide with other units normally (even other flying units).

Best Counters: Kill the Hawk. With an extremely long fade delay and a noteworthy fade time, this low hit point unit is unlikely to survive more than one attack from a hero. Do not waste gold on anti-invisibility counters for this unit.

• Blood Rite only provides ground vision, but it can be placed on levels of terrain above Bloodseeker by casting this spell near a cliff. Blood Rite will provide vision of whatever terrain it is created on.

Bloodseeker – Thirst (does not have a damage type) Tier 2:

• This passive ability is activated by damaged Spell Immune heroes in the same way that it is activated normally.
  
• This passive ability grants speeds faster than the maximum movement speed. Bloodseeker is able to break the 522 speed limit in DotA2 when affected by "Thirst". Bloodseeker's movment speed is not set to any specific value above 522, so he can still be slowed by any slowing effect.
  
• This spell provides fogged vision.
  
• This spell is a noteworthy invisibility counter. Thirst allows Bloodseeker to gain True Sight of invisible units globally when they are at 30% of their total health.

Bloodseeker – Rupture (pure) Tier 1:

• Every effect of this spell affects Spell Immune units.
  
• This spell can be cast on Spell Immune units.
  
• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).

Bounty Hunter (Gondar)

This hero has unique vision ranges. They are as follows:

Day – 1800
Night – 1000

Bounty Hunter – Shuriken Toss (magical) Tier 3:

• This spell is a stun.

Bounty Hunter – Jinada (physical) Tier 1:

• The movement and attack speed slowing effects of this passive ability do affect Spell Immune units.
  
• Gaining Spell Immunity or using a purge on an affected unit removes this debuff.
  
• Couriers are slowed by this passive ability.

Bounty Hunter – Shadow Walk (physical) Tier 2:

• Every effect of this spell affects Spell Immune units.
  
• Casting this spell does not interrupt channeled spells or items.

Bounty Hunter – Track – (does not have a damage type) Tier 1:

• Every effect of this spell affects Spell Immune units.
  
• This spell can be cast on Spell Immune units.
  
• Gaining Spell Immunity or using a purge on an affected unit removes this debuff.
  
• This spell is a noteworthy invisibility counter. "Track" provides True Sight and shared vision of the targeted unit.

Invisibility:

Shadow Walk:

Duration: 20/25/30/35 Seconds (at levels 1/2/3/4 respectively)

Fade Time: 1/.75/.5/.25 Seconds (at levels 1/2/3/4 respectively)

Fade Delay: 0 Seconds (at all levels)

Can be revealed by silence: No

Can phase through other units: Yes

Best Counters: Dust of Appearance or Gem of True Sight. Dust of Appearance is useful to counter the attacks of an aggressive Bounty Hunter. Gem of True Sight forces Bounty Hunter to play much more passively until the Gem holder can be taken out. Due to Bounty Hunter’s high burst damage and carry potential it may be necessary to purchase a Gem if an enemy Bounty Hunter becomes too dangerous.

Notes:

• Bounty Hunter can attack items on the ground without losing invisibility.

Brewmaster (Mangix)

This hero has a smaller collision size than most heroes (only during "Primal Split").

Brewmaster – Thunder Clap (magical) Tier 3:

• This spell has a 8 second duration when applied to creeps.

Brewmaster – Drunken Haze (does not have a damage type) Tier 2:

• This spell cannot be negated by blinking, jumping, gaining invisibility, or transforming.
  
• This spell has a 12 second duration when applied to creeps.

Brewmaster – Primal Split (does not have a damage type) Tier 2:

• This spell grants Spell Immunity to Earth.
  
• Brewmaster is invulnerable for .6 seconds while casting this spell.
  
• Any items that Brewmaster owns that provide Auras will continue to function during “Primal Split”. The Auras will be provided by the Earth element (the Auras will be provided by Storm if Earth is killed and Fire if Earth and Storm are killed).
  
• Earth, Storm, and Fire are treated as ancients for the purposes of targeting spells against them. This means that they cannot be targeted by some powerful spells.

Brewmaster (Earth) – Hurl Boulder (magical) Tier 3:

• This spell is a stun.

Brewmaster (Storm) – Dispel Magic (does not have a damage type) Tier 2:

• This spell is a purge.
  
• Brewmaster can use the purging effect of this spell to dispel any cyclone, even his own. Any unit that is purged out of a cyclone in this way will also be purged (even though they were invulnerable in the cyclone).

Brewmaster (Storm) – Cyclone (does not have a damage type) Tier 3:

• This spell is a disable.
  
• This spell can only be dispelled with Diffusal Blade and Brewmaster's "Dispel Magic".

Invisibility:

Wind Walk:

Duration: 20 Seconds (longer than Primal Split without Aghanim’s Scepter)

Fade Time: .6 Seconds (at all levels)

Fade Delay: 0 Seconds (at all levels)

Can be revealed by silence: No

Can phase through other units: Yes

Best Counters: Since Brewmaster is so unlikely to make frequent use of this skill it is probably not necessary to purchase anti-invisibility items to counter this spell. In the event that you do have Dust of Appearance available, its low cost and low duration (compared to Brewmaster’s low ultimate duration) are a good counter if necessary.

Notes:

• Wind Walk is only available to the Storm during Brewmaster’s “Primal Split”.

Bristleback (Rigwarl)

Bristleback – Viscous Nasal Goo (physical) Tier 3:

• This spell's debuff stacks.
  
• This spell has a 10 second duration when applied to creeps.

Bristleback – Quill Spray (physical) Tier 1:

• Every effect of this spell affects Spell Immune units.
  
• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• This spell's debuff stacks.
  
• The damage dealt by this spell is reduced by armor but it is not reduced by damage block.

Bristleback – Bristleback (does not have a damage type) Tier 2:

• Bristleback’s “back” is a 70° angle behind him. Bristleback’s “side” is a 110° angle behind him.
  
• This passive ability does not affect damage that Bristleback takes from Towers.

Bristleback – Warpath (does not have a damage type) Tier 2:

• This passive ability cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• This passive ability's buff stacks.

Broodmother (Black Arachnia)

Broodmother – Spawn Spiderlings (magical) Tier 3:

• The units spawned by this spell block creep camp spawns.

Broodmother – Spin Web (does not have a damage type) Tier 3:

• “Spin Web” can be used to pass through physical barriers. The following spells can be escaped or negated with “Spin Web”:
  
  • Clockwerk’s “Power Cogs”
    
  • Earthshaker’s “Fissure”
    
  • Nature’s Prophet’s “Sprout”
    
  • Shadow Shaman’s “Mass Serpent Ward”
    
  • Tusk’s “Ice Shards”

• This spell cannot be dispelled with Spell Immunity or any type of allied purge (Black King Bar, Manta Style, Diffusal Blade, etc…).

Invisibility:

Spin Web (Invisible):

Duration: Infinite

Fade Time: 0 Seconds (at all levels)

Fade Delay: 2 Seconds (at all levels)

Can be revealed by silence: Sort of (if Broodmother is in her web and is silenced before she can fade out she will not be able to fade out until the silence debuff ends)

Can phase through other units: No

Best Counters: Sentry Wards are the best way to prevent Broodmother from using her invisibility effectively since you will know the only potential places that she (and her brood) can remain invisible. Dust of Appearance is not as useful against Broodmother since she will often use her extremely high speed when hiding in her webs to skitter away before she can be killed. A Gem of True Sight may be necessary when facing an aggressive or successful Broodmother. Broodmother's free movement is canceled when she takes damage in a web. This makes area of effect spells more useful against her than against other invisible heroes. If Broodmother takes damage for any reason (even if she is already revealed by true sight) in one of her webs any nearby trees will be automatically destroyed (this effect also applies to her Spiderlings and Spiderites). Remember that Broodmother's free movement is not tied to her invisibility (she can still climb cliffs and pass through anything even when revealed or silenced to prevent invisibility).

Chaos Knight – Reality Rift (does not have a damage type) Tier 3:

• This spell is a purge (only on Chaos Knight).

Chen

Chen – Test of Faith (allied version) (does not have a damage type) Tier 3:

• This spell can be cast on Spell Immune allies.

Fade Time: .6 Seconds (at all levels)

Fade Delay: 0 Seconds (at all levels)

Can be revealed by silence: No

Can phase through other units: Yes

Best Counters: Dust of Appearance or Gem of True Sight. Dust of Appearance is less useful against Clinkz since he can escape very quickly from a failed assassination attempt, but it can save lives in the early game against an aggressive Clinkz. Gem of True Sight is the best counter to Clinkz since he relies on his stealth and the relatively short term “Death Pact” to cover for his innately low durability.

Clockwerk (Rattletrap)

Clockwerk – Battery Assault (magical) Tier 2:

• This spell is a silence.
  
• This spell does not affect units in Enigma's "Black Hole", Faceless Void's "Chronosphere", or Legion Commander's "Duel". The cooldown will begin and the mana will be wasted.

• This spell destroys trees.

Earth Spirit – Magnetize (magical) Tier 1:

• The magnetizing effect of this area of effect spell will affect Spell Immune units in its radius.
  
• The slowing effect of this area of effect spell will affect Spell Immune units in its radius (if any magnetized hero is slowed by “Rolling Boulder”).
  
• This spell is a silence (if any magnetized hero is silenced by “Boulder Smash”).
  
• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• This spell can be transferred from affected magnetized Spell Immune units to other units.
  
• This spell can help to track invisible units. The lightning bolts that are generated by exploding Stone Remnants arc to nearby invisible units, pointing out their position and damaging them.

• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• This spell deals magical and physical damage. If an enemy is only inside the area of Elder Titan’s “Echo Stomp” then the spell’s full damage will be dealt as physical damage. If an enemy is only inside the area of Astral Spirit’s “Echo Stomp” then the spell’s full damage will be dealt as magical damage. If an enemy is inside the area of both spells (if Elder Titan’s Astral Spirit isn’t deployed or is just very close) then the spells damage will be dealt as half physical and half magical (meaning it will be reduced by both armor and magic resistance). In practice this means that “Echo Stomp” will almost always deal more damage when only one type of damage is dealt.

• With this passive ability Faceless Void has a chance to dodge (not evade) any attack OR spell with any damage type (except hp modification). While Faceless Void always has a chance to avoid potential damage, he does still always suffer the negative effects associated with spells (such as Stun, Silence, Hex, Banish, Disable, etc...).
  
• Dodge is different than evasion and it does stack with evasion chance (not additively).
  
• Monkey King Bar wielders can miss Faceless Void when this passive ability procs (this is the only ability in DotA2 that can cause a hero with Monkey King Bar to miss).

• Gaining Spell Immunity or using a purge on an affected unit removes this debuff, but if the affected unit is still inside the area of effect of “Call Down” and the second strike has not yet hit then this will be relatively pointless since a second more powerful slowing debuff is applied with the second strike.

Invisibility:

Ghost Walk:

Duration: 100 Seconds

Fade Time: 0 Seconds (at all levels)

Fade Delay: 0 Seconds (at all levels)

Can be revealed by silence: No

Can phase through other units: Yes

Best Counters: Dust of Appearance or Sentry Wards. Dust of Appearance is the cheapest and most effective way to counter Invoker’s invisibility since his position will be obvious. Sentry Wards can also be used due to his likely lower movement speed when invisible and the low probability that he will notice when a Sentry Ward is dropped near him. In the extremely unlikely event that Invoker survives the duration of the Dust, a Sentry would have probably been superior.

Notes:

• The slowing aura created by this spell will persist for 2 seconds after the invisibility is removed.

• This spell is a stun.
  
• This spell can help to track invisible units. "Earth Spike" will cause a special visual effect when it collides with any unit, even an invisible one. This larger spike effect appears directly under a unit that is hit by the spell and can be used to target more area of effect spells.

Lion – Hex (does not have a damage type) Tier 3:

• This spell is a hex. Movement speed is reduced to 140.

• This spell destroys illusions.

Lion – Finger of Death (magical) Tier 3:

• This spell has a .25 second delay between the cast point and the time that the damage is dealt. This allows spells and items that grant Spell Immunity, invulnerability, or banishes to negate this spell entirely if well timed.
  
• With Aghanim's Scepter this spell hits in an area around the target unit instead of only hitting the target unit. If this spell is negated in any of the ways stated above it will still hit all available units in the area of effect.

Lone Druid (Sylla)

Lone Druid (Spirit Bear) – Return (does not have a damage type) Tier 2:

• Spirit Bear can negate some projectiles with the blink effect of “Return”. The cast/attack animation for the projectile must have ended for this spell to dodge successfully (meaning the projectile will be in flight).

Lone Druid (Spirit Bear) – Entangling Claws (physical) Tier 1:

• This spell is an ensnare.
  
• Every effect of this passive ability affects Spell Immune units.
  
• Gaining Spell Immunity or using a purge on an affected unit removes this debuff.

  • The Spirit Bear’s damage will not be increased when picking up a Double Damage Rune.

• Every effect of this spell affects all Spell Immune allied units that are eligible for its effects.

Fade Delay: 1.7 Seconds (this skill only exists at levels 3/4)

Can be revealed by silence: Yes

Can phase through other units: No

Best Counters: Kill the Wolves. These units need to be prioritized when they attack if possible due to their relatively high damage potential. Using Dust of Appearance or Sentry Wards against these units is a waste due to their high speed if they choose to disengage.

• This spell can be cast on Spell Immune allies.
  
• This spell cannot be dispelled with Spell Immunity or any type of allied purge (Black King Bar, Manta Style, Diffusal Blade, etc…).

  • Petrified units only take bonus physical damage from attacks. Physical spells do not deal any additional damage (but they still deal damage normally).

• Meepo can use “Poof” to teleport to illusions of himself.

Meepo – Geostrike (magical) Tier 1:

• The slowing effect of this passive ability does affect Spell Immune units.
  
• Gaining Spell Immunity or using a purge on a unit affected by “Geostrike” removes any stacks of “Geostrike” currently applied to that unit.
  
• This passive ability's debuff stacks. Each Meepo can apply a copy of this debuff, but a single Meepo cannot apply more than one stack.

Meepo – Divided We Stand (does not have a damage type) Tier 3:

• Meepo clones are treated as heroes by almost all spells and abilities in the game. Exceptions:
  
  • Dark Seer's "Wall of Replica" will only create one Meepo illusion, regardless of which one passes through it first. It will not deal damage to or create new illusions of any other Meepos that pass through the wall until the original illusion is destroyed.
    
  • Doom's "Doom" does not silence the use of active boot abilities if the Meepo prime is affected by "Doom".
    
  • Earth Spirit's "Magnetize" does not transfer or propagate the slow of "Rolling Boulder" or the silence of "Geomantic Grip" debuffs between clones.
    
  • Rubick's "Spell Steal" will steal whatever spell was used last by the collective Meepo. Targeting a clone that has never used a spell is possible if Meepo prime or any other clone has used a spell.
    
  • Zeus's "Thundergod's Wrath" only hits Meepo prime.
• Meepo clones cannot pick up Runes.
  
• With Aghanim's Scepter attributes stolen by non-permanent spells and abilities from Meepo prime will affect the clones. Without Aghanim's Scepter the clones are not affected by attribute stealing effects (unless they are permanent, like Silencer's "Stolen Intelligence").
  
• Spells that steal base stats (such as Razor's "Static Link" or Visage's "Grave Chill") do not affect the clones.
  
• Meepo clones cannot use the active abilities of Arcane Boots or Power Treads, but they can benefit from the effects of both if Meepo himself uses these abilities (assuming they are within range of the Arcane Boots).

Mirana

Fade Delay: 2.5/2/1.5 Seconds (at levels 1/2/3 respectively)

Can be revealed by silence: Sort of (units that are silenced before the initial fade or after they intentionally break the invisibility cannot fade out even when they are affected by this spell)

Can phase through other units: No

Best Counters: Dust of Appearance or Gem of True Sight. Dust of Appearance is the cheapest way to ensure that Mirana doesn’t use this spell to save critically hurt allies. Gem of True Sight is the best way to prevent Mirana from using this spell offensively to initiate unsuspecting team fights.

Morphling

Morphling – Waveform (magical) Tier 2:

• Morphling is invulnerable during “Waveform”.
  
• Morphling can take some actions while in “Waveform”. Morphling can take the following actions during “Waveform”:

      • Pipe of Insight
        
      • Smoke of Deceit

• This spell destroys trees when it pushes enemy units.

Morphling – Morph (does not have a damage type) Tier 2:

• Morphling can cast either variant of the “Morph” spell when he is stunned, disabled, banished, entangled, ensnared, or taunted. Morphling cannot cast “Morph” when he is silenced, hexed, or doomed (since these are all silence effects).

• This spell can target and replicate Spell Immune units.
  
• Morphling cannot use “Replicate” on any illusion of himself that he controls (Manta Style, Illusion Rune). Morphling can use “Replicate” on illusions of himself that he does not control (Shadow Demon’s “Disruption”, Dark Seer’s “Wall of Replica”).

• Any illusions of Naga Siren that are controlled by Naga Siren, regardless of their source (Illusion Rune, Manta Style, etc…), will cast “Rip Tide” when Naga Siren casts “Rip Tide”.

Naga Siren – Song of the Siren (does not have a damage type) Tier 1:

• This spell is a disable.
  
• This spell cannot be dispelled on Naga Siren with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).

Nature’s Prophet – Sprout (does not have a damage type) Tier 2:

• This spell does trap Spell Immune enemy units but it cannot be targeted (directly) on them.
  
• This spell can be cast on Spell Immune allies.
  
• “Sprout” can be used to push enemy or allied units into or out of barriers, tethers, and disables by positioning “Sprout” in such a way that a unit does not have space to exist between the trees and the boundaries of the spell you are attempting to reposition within (or without).

• This spell destroys trees.

Nature’s Prophet – Wrath of Nature (magical) Tier 3:

• This spell can be cast on Spell Immune units (it will bounce from them if they are in line of sight). These bounces (even though they don’t deal damage) do increase the amount of damage that consecutive bounces will deal.

Necrophos (Rotund'jere)

Necrophos – Death Pulse (magical) Tier 2:

• The heal effect of this spell does affect Spell Immune units.
  
• A projectile is generated for Spell Immune enemy units. If a previously Spell Immune enemy unit lost Spell Immunity before the projectile hits the unit, it will take the damage normally.
  
• This spell cannot be negated by blinking, jumping, gaining invisibility, or transforming.
  
• This spell can help to track invisible units. Projectiles generated by "Death Pulse" do damage invisible units and the projectiles generated by this area of effect spell will follow invisible units to their current position.

Necrophos – Heartstopper Aura (negative regeneration) Tier 3:

• This passive ability does not display on the buff bar of enemy heroes when Necrophos is invisible (or otherwise not visibile for any reason - including being in the fog of war). This passive ability still deals full damage when Necrophos is invisible.

Necrophos – Sadist (does not have a damage type) Tier 2:

• This passive ability cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).

• This spell is a stun.

Night Stalker – Crippling Fear (does not have a damage type) Tier 3:

• This spell is a silence.

Nyx Assassin

Nyx Assassin – Impale (magical) Tier 3:

• This spell is a stun.
  
• This spell can help to track invisible units. "Impale" will cause a special visual effect when it collides with any unit, even an invisible one. This larger spike effect appears directly under a unit that is hit by the spell and can be used to target more area of effect spells.

Nyx Assassin – Spiked Carapace (pure) Tier 2:

• This spell is a stun.
  
• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• Spells that deal hp modification will not cause the retaliatory damage or stun dealt by “Spiked Carapace”.
  
• Summoned units, illusions, mines, and wards that deal damage to Nyx Assassin when "Spike Carapace" is active will not cause the hero that owns them to be stunned.
  
• Invulnerable units deal full damage to Nyx Assassin without receiving any damage or stun from “Spike Carapace”. “Spiked Carapace” only has one “charge”, meaning that if an invulnerable unit attacks Nyx Assassin during “Spiked Carapace” they cannot be damaged or stunned by any future attacks to Nyx Assassin even if “Spiked Carapace” is still active. Eul’s Scepter of Divinity can be used to avoid the return damage of most spells (animation canceling may be necessary – queuing the “Cyclone” spell may not be fast enough). The following spells will deal damage to Nyx Assassin without any potential for return damage (any hero with access to invulnerability can theoretically negate “Spiked Carapace” with proper timing, depending on their method of attack):
  
  • Brewmaster's "Primal Split" (any attack from the Elements)
    
  • Ember Spirit’s “Activate Fire Remnant”
    
  • Juggernaut’s “Omnislash”
    
  • Lifestealer’s “Infest”
    
  • Morphling’s “Wave Form”
    
  • Phoenix's "Supernova"
    
  • Storm Spirit’s “Ball Lightning”
    
  • Tusk’s “Snowball”
• Some spells and passive abilities can cause an attack to damage Nyx Assassin when “Spiked Carapace” is active. Any damage over time spell or passive ability will do this since multiple damage instances are caused. The following spells and passive abilities without a damage over time component can also cause attacks to deal significant damage to Nyx Assassin when “Spiked Carapace” is active (the attacker will still be stunned and receive the base attack damage):
  
  • Ancient Apparition’s “Chilling Touch”
    
  • Batrider’s “Sticky Napalm”
    
  • Bounty Hunter’s “Shadow Walk”
    
  • Enchantress’s “Impetus”
    
  • Outworld Devourer’s “Arcane Orb”
    
  • Silencer’s “Glaives of Wisdom”
    
  • Spectre’s “Desolate”
    
  • Spirit Breaker’s “Greater Bash”
    
  • Storm Spirit’s “Overload”
    
  • Templar Assassin’s “Meld”
    
  • Weaver’s “Geminate Attack”
• Damage dealt by "Blade Mail" deals full damage to Nyx Assassin without receiving any damage or stun from “Spike Carapace”.

Nyx Assassin – Vendetta (physical) Tier 2:

• Every effect of this spell affects Spell Immune units.
  
• Casting this spell does not interrupt channeled spells or items.

Invisibility:

Vendetta:

Duration: 20/35/50 Seconds (at levels 1/2/3 respectively)

Fade Time: 0 Seconds (at all levels)

Fade Delay: 0 Seconds (at all levels)

Can be revealed by silence: No

Can phase through other units: Yes

Best Counters: Sentry Wards or Gem of True Sight. Sentry Wards prevent Nyx Assassin from initiating successfully in a team fight that is about to occur because of a tower push or random encounter. Gem of True Sight is the best counter to Nyx Assassin’s invisibility, but it must be used with caution due to Nyx Assassin’s high burst damage. Dust of Appearance is rarely useful against Nyx Assassin since he will almost always initiate with “Vendtta” instead using it as an escape mechanism. When he does use “Vendetta” to escape he will move so quickly that Dust may not be effective.

Notes:

• Nyx can attack items on the ground without losing invisibility.

Ogre Magi (Aggron Stonebreak)

Ogre Magi – Fireblast (magical) Tier 3:

• This spell is a stun.

Ogre Magi – Ignite (magical) Tier 3:

• This spell can help to track invisible units. "Ignite" will randomly target enemy and neutral units when it procs "Multicast". This causes the projectile to seek invisible units, signifying their positions and dealing damage to them.

Ogre Magi – Bloodlust (does not have a damage type) Tier 2:

• This spell cannot be dispelled with Spell Immunity or any type of allied purge (Black King Bar, Manta Style, Diffusal Blade, etc…).

Omniknight (Purist Thunderwrath)

Omniknight – Purification (pure) Tier 3:

• This spell can target siege creeps.

Omniknight – Repel (does not have a damage type) Tier 1:

• This spell grants Spell Immunity to Omniknight's target.
  
• This spell can be cast on Spell Immune allies.
  
• This spell can be purged by any purge that affects Spell Immune units or by Diffusal Blade.
  
• “Repel” provides different types of Spell Immunity depending on whether the Omniknight that cast “Repel” was on the same team as the unit that the spell was cast on. Some allied buffs can be cast on Spell Immune allied units (as noted throughout this guide), but these buffs cannot be able to be applied if an enemy Omniknight has already cast “Repel” on the target, since this is not allied Spell Immunity. If a hero uses Black King Bar while affected by an enemy Omniknight’s “Repel” their type of Spell Immunity will be switched, and buffs that can normally be cast on allied Spell Immune units will now be able to be cast on them.
  
• “Repel” removes Ghost Scepter's "Ghost Form" buff from allies.
  
• “Repel” cannot be cast on an enemy unit that is currently protected by enemy Spell Immunity.
  
• This spell can target siege creeps.
  
• This spell can be cast on couriers.

Omniknight – Degen Aura (does not have a damage type) Tier 2:

• The slowing effects of this passive ability do affect Spell Immune units.
  
• This passive ability affects siege creeps.

Omniknight – Guardian Angel (does not have a damage type) Tier 2:

• This spell does affect Spell Immune allies (meaning they will be completely resistant to both magical and physical damage).
  
• This spell cannot be dispelled with Spell Immunity or any type of allied purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• This spell prevents all damage from physical type spells and abilities including cleaves and splash damage. Stuns and effects applied by physical spells are not blocked in any way.
  
• With Aghanim’s Scepter this spell can heal structures.
  
• This spell affects siege creeps.

Oracle (Nerif)

Oracle – Fortune's End (magical) Tier 2:

• This spell is a stop.
  
• This spell can target invulnerable units.
  
• This spell cannot be negated entirely by blinking, jumping, or gaining invisibility. The projectile will still land at the last valid location of the target. If a blink or jump is very short the projectile may still hit. If an invisible unit fades out but is still in the area of effect it will be hit.
  
• This spell is a purge (any units within the area of effect are purged).
  
• This spell can block creep camp spawns.
  
• This spell can purge invulnerable units (it cannot purge banished units).
  
• This spell purges before it deals damage. Any positive buffs that can be removed (including "Purifying Flames") will be removed first. Even though "Fate's Edict" is not a positive buff, it will also be purged by "Fortune's End".
  
• This spell can help to track invisible units. "Fortune's End" tracks any unit it is fired at, even if that unit has become invisible since the projectile was fired. The area of effect caused by this spell can still stop, purge, deal damage, and provide ground vision. Oracle will also rotate to keep facing invisible enemies while he casts this spell. If a phased enemy attempts to juke by passing through you this will be obvious.

Oracle – Fate's Edict (does not have a damage type) Tier 2:

• This spell is a disarm.
  
• This spell can only be dispelled with Spell Immunity and Oracle's "Fortune's End". This spell cannot be purged (Manta Style, Diffusal Blade, Eul’s Scepter of Divinity, etc…).
  
• This spell can target siege creeps.

Oracle – Purifying Flames (magical) Tier 3:

• This spell's buff stacks.
  
• The damage dealt by this spell is always non-lethal to allies.

Oracle – False Promise (does not have a damage type) Tier 1:

• This spell can be cast on Spell Immune allies.
  
• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• This spell is a purge.
  
• This spell purges some debuffs that cannot normally be purged:
  
  • Bane’s “Nightmare”
    
  • Elder Titan’s “Echo Stomp”
    
  • Enigma’s “Malefice”
    
  • Invoker’s “Cold Snap”
    
  • Venomancer’s “Venomous Gale”
• This spell can negate all stuns and many disables once they have been applied (even channeled disables like Pudge’s “Dismember” or Bane’s “Fiend’s Grip” and tethers like Batrider’s “Flaming Lasso” or Slark’s “Pounce”) except for Necrophos’s “Reaper’s Scythe”.
  
• This spell cannot negate taunts.
  
• Healing is always applied before damage when all totals are calculated at the end of this spell's delayed effect duration.
  
• Units that take damage during "False Promise" do not ever actually count as being hit because the instances of damage applied when the buff ends are an HP modification. This means that allied buffs like "Living Armor", "Aphotic Shield", and "Ghost Ship" have no effect at all, while on the other hand Visage will never receive any "Soul Assumption" charges for damage dealt during "False Promise". This also means that effects like Blade Mail's "Damage Return" are not effective while affected by "False Promise".
  
• The particle effect above units that currently benefit from "False Promise" changes depending on how much healing and damage have been accumulated over the duration of the buff. Notice that the sphere above the unit does not initially have any special effects. The more glowing green motes that float around the sphere the more the unit will be healed. The more red flames that appear on the sphere itself the more the unit will be damaged. Since both of these effects will placed on the sphere at the same time it can get very visually noisy, but it gives you a basic indication of healing and damage dealt.
  
• Some HP modifications will still modify the hit points of units affected by "False Promise", despite the fact that these units cannot take damage. This means that Armlet of Mordiggian and Terrorblade's "Sunder" will still affect these units normally.

Invisibility:

False Promise:

Duration: 7/8/9 Seconds (at levels 1/2/3 respectively)

Fade Time: 0 Seconds (at all levels)

Fade Delay: 0 Seconds (at all levels)

Can be revealed by silence: No

Can phase through other units: No

Best Counters: Dust of Appearance is an effective counter to this spell unless other heroes on Oracle's team can purge it easily. Oracle will not be able to purge Dust of Appearance easily since the spell that you are seeking to reveal is also his allied purge. Sentry Wards or Gem of True Sight may be required against a competent Oracle and a team that makes good use of this spell. Invisible initiators and gankers are much harder to counter with Dust of Appearance.

Notes:

• Units can attack, use items, and use abilities during False Promise’s invisibility.
  
• The spherical particle effect that can be seen enemies have True Sight of a unit affected by this spell will reveal to enemies how much relative healing and damage have been accumulated over the duration of this spell.

• This spell destroys illusions.
  
• Pugna can use this spell to deny himself.
  
• The life drained by this spell is the same as the damage done. If a target is ethereal (because the target is affected by Pugna’s “Decrepify”) considerably more health will be drained because decrepified targets receive 1.5x magical damage. A target with high magical resistance will have less health drained.
  
• Couriers are healed by this spell.

Queen of Pain – Shadow Strike (magical) Tier 2:

• Allies affected by this spell can be denied.

• This spell provides shared vision.
  
• This spell can help to track invisible units. "Static Link" does not break when a unit becomes invisible. This means that Razor and his team can follow the tether to track the position of the invisible unit until the tether breaks or the spell ends.

Razor – Unstable Current (magical) Tier 2:

• This passive ability is a purge.
  
• Only spells that target Razor directly can proc this retaliatory purge. Area of effect spells will not proc this passive ability.

• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…) on Razor or on enemies affected by the armor decreasing debuff.

Riki – Blink Strike (magical) Tier 1:

• This spell can be cast on Spell Immune units.

Invisibility:

Permanent Invisibility:

Duration: Infinite

Fade Time: 0 Seconds (at all levels)

Fade Delay: 8/6/4/2 Seconds (at levels 1/2/3/4 respectively)

Can be revealed by silence: Yes

Can phase through other units: No

Best Counters: Gem of True Sight forces Riki to play much more passively until the Gem holder can be taken out. Since he can be watching your team at any time and has noteworthy carry potential, it may be necessary to purchase a Gem if an enemy Riki becomes too dangerous. Dust of Appearance is useful to counter the attacks of an aggressive Riki. Sentry Wards are useful against Riki when preparing for a tower push or team fight. Either of the aforementioned options may be necessary until a hero on your team is tough enough to survive being focused by the enemy team because of their ownership of a gem.

Notes:

• Riki is not revealed by using items or casting spells. Blink Strike will only reveal Riki if he casts it on an enemy or neutral unit or hero.

Rubick

Rubick – Telekinesis (does not have a damage type) Tier 3:

• This spell is a disable/stun (disables primary target, stuns any targets near landing point).
  
• The disable portion of this spell can be negated by most spells that reposition heroes, knock heroes into the air, and a few other special spells.

Area of effect Unit Target spells can also sometimes be avoided if Sand King is not the targeted unit. Some of the following spells' areas are too large to burrow directly under, but burrowing into these effects will not affect Sand King until he emerges, and Sand King can often burrow out of these dangerous areas even if he can't cross them.

  • Ancient Apparition's "Ice Vortex"
    
  • Centaur Warrunner's "Stampede"

  • Storm Spirit's "Static Remnant"
    
  • Tinker's "March of the Machines"

  • Earthshaker's "Fissure"
    
  • Jakiro’s “Ice Path”
    
  • Nature's Prophet's "Sprout"
    
  • Shadow Shaman's "Mass Serpent Ward"
    
  • Tusk's "Ice Shards"
• This spell can be used to reposition in any root (Naga Siren’s “Ensnare”, Meepo’s “Earthbind”, Treant Protector’s “Overgrowth”, etc…).

Sand King – Caustic Finale (magical) Tier 2:

• This passive ability cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).

Sand King – Epicenter (magical) Tier 1:

• The slowing effect of this area of effect spell will affect Spell Immune units in its radius.
  
• Gaining Spell Immunity or using a purge on an affected unit removes this debuff, but if the affected unit is still near Sand King and the “Epicenter” is still active then this will be relatively pointless since the debuff is continuously applied.
  
• Couriers are slowed by this spell.

Invisibility:

Sand Storm:

Duration: 20/40/60/80 Seconds (at levels 1/2/3/4 respectively)

Fade Time: 0 Seconds (at all levels)

Fade Delay: 0 Seconds (at all levels)

Can be revealed by silence: Yes

Can phase through other units: No

Best Counters: Dust of Appearance is the cheapest and best way to counter Sand King’s stationary and obvious invisibility spell. Sentry Wards or Gem of True Sight should only be considered when other invisible heroes are also causing difficulty for your team as well.

Notes:

• The invisibility granted by this spell will persist for 1.5 seconds after the spell has ended at all levels. If Sand King takes any actions other than movement during this period of invisibility he will be revealed instantly (casting any spells, attacking, using items, etc…).
  
• This is the only invisibility spell that is also a channeled spell. This spell can be cancelled with spells that interrupt/silence/stun. Movement cancels this spell (like any other channeled spell).

Shadow Demon

Shadow Demon – Disruption (does not have a damage type) Tier 2:

• This spell is a banish.
  
• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• Allied heroes (including Shadow Demon) are invulnerable when affected by “Disruption”.

Shadow Demon – Soul Catcher (pure) Tier 2:

• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• This spell can help to track invisible units. "Soul Catcher" amplifies damage against invisible targets within its area of effect and creates a special particle effect that will signify the position of an invisible unit if it successfully catches such a unit. Shadow Demon will also confirm whether the "Soul Catcher" was successful or not with a positive or negative voice over response. Unfortunately Shadow Demon sometimes speaks in his native Ozkavosh tongue. The only successful "Soul Catcher" voice over response that Shadow Demon speaks in Ozkavosh is "Izh icha safras" (pronounced Eezs ih-HHA sah-FRAHS), directly translated as: "You will suffer."

• The first debuff placed by this spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…). Once this spell has silenced and/or disarmed the target the second debuff can be removed with Spell Immunity or a purge normally.
  
• “Last Word” deals damage directly before an enemy casts a spell except in the case of channeled spells (channeled spells pause the first countdown debuff). This means that almost all burst self-heals, self-applied Spell Immunity, self-applied invulnerability, and retaliatory spells will not protect in any way from the damage that “Last Word” deals. Only one spell of the aforementioned types in DotA2 negates “Last Word” damage and negative effects:
  
  • Puck’s “Phase Shift” (Puck must wait the entire duration of “Phase Shift” to avoid the damage)

  • Bane’s “Nightmare”
    
  • Elder Titan’s “Echo Stomp”
    
  • Enigma’s “Malefice”
    
  • Invoker’s “Cold Snap”
    
  • Medusa's "Stone Gaze"
    
  • Venomancer’s “Venomous Gale”
• This spell can negate all stuns and many disables once they have been applied (even channeled disables like Pudge’s “Dismember” or Bane’s “Fiend’s Grip” and tethers like Batrider’s “Flaming Lasso” or Slark’s “Pounce”) except for Necrophos’s “Reaper’s Scythe”.
  
• This spell cannot negate taunts.
  
• This spell cannot be canceled through any means, even if Slark is stunned or otherwise disabled before the purge is applied during the 1.5 second delay.

Slark – Pounce (magical) Tier 2:

• This spell cannot be purged (Manta Style, Diffusal Blade, Eul’s Scepter of Divinity, etc…).
  
• Slark can negate some projectiles with the jump effect of “Pounce”. The cast/attack animation for the projectile must have ended for this spell to dodge successfully (meaning the projectile will be in flight).
  
• Any spell or ability that repositions a hero in any way (whether cast by an allied or enemy hero) can break the tether effect of this spell with the following exceptions:
  
  • Force Staff’s “Force”
    
  • Magnus’s “Skewer”
    
  • Mirana’s “Leap”
    
  • Slark’s “Pounce”
• This spell destroys trees.
  
• This spell can help to track invisible units. "Pounce" leashes and deals damage to invisible units that Slark collides with.

Slark – Essence Shift (does not have a damage type) Tier 1:

• Every effect of this passive ability affects Spell Immune units.
  
• The stat-stealing debuff caused by this passive ability cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).

Slark – Shadow Dance (does not have a damage type) Tier 3:

• "Shadow Dance" will not provide any bonus movement speed or HP regeneration when any enemy unit has vision of Slark. Slark can use this knowledge to determine when he is being affected by global vision abilities like Spirit Breaker's "Charge of Darkness".
  
• This passive ability can help to track invisible units. By watching the buff bar for "Shadow Dance's" presence and by observing Slark’s stats change (movement speed and HP regeneration) you can see when an invisible enemy unit is hiding nearby or when you are visible to wards.

Invisibility:

Shadow Dance:

Duration: 4 Seconds (at all levels)

Fade Time: 0 Seconds (at all levels)

Fade Delay: 0 Seconds (at all levels)

Can be revealed by silence: No

Can phase through other units: No

Best Counters: None of the normal invisibility counters will allow you to detect Slark during Shadow Dance. Area of effect stuns, disables and slows may be useful depending on your positioning with relation to Slark. Be ready to punish Slark when his invisibility ends. This spell’s long cooldown will prevent him from using it to escape after a dive attempt.

Notes:

• No detection of any kind will allow you to target Slark during his Shadow Dance.
  
• Slark can attack, use items, and use abilities during Shadow Dance’s invisibility.
  
• Slark is surrounded by a dark cloud that is completely visible to enemies at all times when he uses Shadow Dance.
  
• Any time that Slark is not visible to the enemy (not necessarily invisible – he could just be in the fog of war in some location they can’t see) he benefits from this ability’s passive health regeneration and speed bonuses. Any kind of vision counts for this effect including towers, lane creeps, player controlled units, and wards.
  
• If Slark takes damage from a neutral unit (like Roshan or a jungle creep) he loses the passive bonuses of this ability for 2 seconds.

• This spell can target invulnerable units.
  
• This spell is a noteworthy invisibility counter. "Assassinate" provides True Sight and shared vision of the targeted unit until the unit is hit by the projectile generated by this spell.

• This spell provides flying vision while in flight and shared vision on affected units.
  
• This spell can help to track invisible units. "Spectral Dagger" can be targeted on the ground to throw the dagger in a direction that you believe an invisible unit is hiding.

• This passive ability deals pure damage to surrounding enemies but this damage is treated as an hp modification for purpose of items that are interrupted by damage. The following items are not interrupted by “Dispersion”: Blink Dagger, Heart of Tarrasque, Healing Salve, Clarity, and Bottle (meaning that these items will not be put on cooldown or be canceled when receiving “Dispersion” damage).

• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• This spell grants speeds faster than the maximum movement speed. Spirit Breaker is able to break the 522 speed limit in DotA2 when charging. Any slowing effects applied to Spirit Breaker during “Charge of Darkness” will alter his movement speed stat in the stat pane but he will not actually slow down. Since Spirit Breaker's speed is set higher than maximum movement speed during “Charge of Darkness” he cannot be slowed.
  
• This spell cannot be negated by blinking, jumping, gaining invisibility, or transforming.
  
• This spell is disabled by entangles and ensnares.
  
• Spirit Breaker can use some items while charging without breaking the charge. Most items with No Target abilities can be used in this way.

• This spell can help to track invisible units. "Charge of Darkness" is not interrupted when a targeted unit becomes invisible. The charge indicator will still appear above the invisible unit’s head regardless of where it goes and some vision will be provided of the targeted unit’s position. This doesn’t mean that Spirit Breaker or his team can attack this unit, but they will know the unit’s exact location until the charge ends.

Fade Delay: 2 Seconds (at all levels)

Fade Time: 0 Seconds (at all levels)

Fade Time: 0 Seconds (at all levels)

Fade Delay: 2 Seconds (at all levels)

Can be revealed by silence: No

Psionic Trap:

Duration: Infinite

Fade Time: 0 Seconds (at all levels)

Fade Delay: 2 Seconds (at all levels)

Can be revealed by silence: No

Can phase through other units: Yes

• This passive ability cannot negate taunts.
  
• If the damage from a stun or disable would cause Tidehunter’s hit points to cross this passive ability’s damage threshold then that spell will apply normally.

• This spell is a disable (the thrown unit is disabled, not the target of spell unless the target is also the unit thrown).
  
• Spell Immune units can be tossed but they will not take damage.
  
• If Tiny uses “Toss” on a unit that is currently within the area of effect of an active “Avalanche” then the remaining damage over time dealt by “Avalanche” will be doubled against this unit.

Invisibility:

Nature’s Guise:

Duration: 15/30/45/60 Seconds (at levels 1/2/3/4 respectively)

Fade Time: 2 Seconds (at all levels)

Fade Delay: 0 Seconds (at all levels)

Can be revealed by silence: No

Can phase through other units: No

Best Counters: Sentry Wards or Gem of True Sight. Dust of Appearance is less useful (but not worthless since he has no other escape) against Treant Protector since he is likely to be watching you from the trees at any given moment without attacking. Sentry Wards provide protection from his invisible spell casting shenanigans when a team fight is about to start. Gem of True Sight will completely shut down his team-buffing potential and help to de-ward the wards he is likely to be placing, but this is a more expensive option to counter a spell that he may not use proactively.

Notes:

• Treant Protector can use abilities and items without cancelling the invisibility effect of Nature’s Guise.
  
• Nature’s Guise can be purged.

Eyes In The Forest:

Duration: Infinite

Fade Time: 0 Seconds

Fade Delay: 0 Seconds

Can be revealed by silence: No

Can phase through other units: No

Best Counters: Gem of True Sight is the best counter to Treant Protector's omnipresent spy trees.

• This spell can be cast on Spell Immune allies.

Venomancer – Poison Sting (magical) Tier 1:

• The slowing effect of this passive ability does affect Spell Immune units.
  
• This passive ability cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• This passive ability's debuff stacks with itself if Venomancer and a Plague Ward have both placed the debuff, but both cannot deal damage simultaneously. Venomancer's higher damage "Poison Sting" from the hero himself will always deal damage first if it is applied to the target before the "Poison Sting" applied by the Plague Wards.
  
• This passive ability deals magical damage but it is treated as an hp modification for purpose of items that are interrupted by damage. The following items are not interrupted by “Poison Sting”: Blink Dagger, Heart of Tarrasque, Healing Salve, Clarity, and Bottle (meaning that these items will not be put on cooldown or be canceled when receiving “Poison Sting” damage).
  
• Couriers are slowed by this passive ability.

Weaver – Shukuchi (magical) Tier 2:

• Casting this spell does not interrupt channeled spells or items.

  • Enigma’s “Malefice”

Shukuchi:

Duration: 4 Seconds (at all levels)

Fade Time: .25 Seconds (at all levels)

Fade Delay: 0 Seconds (at all levels)

Can be revealed by silence: No

Can phase through other units: Yes

Best Counters: Weaver’s invisibility is very difficult for any single counter to be effective against, depending on how he chooses to use “Shukuchi” (too fast for Dust or Sentrys, too short to be worth the attention of a Gem). The short duration of “Shukuchi” may be reason enough for your team to ignore invisibility counters when facing Weaver all together. Even though “Shukuchi” is hard to counter well, the basic rules still apply. Use Dust of Appearance against a Weaver using “Shukuchi” aggressively but don’t forget that Weaver can always purge Dust of Appearance if he wants to spend “Time Lapse”. Use a Gem of True Sight if necessary to prevent Weaver from escaping from team fights.

Windranger (Lyralei)

Windranger – Shackleshot (does not have a damage type) Tier 2:

• This spell is a stun.
  
• This spell cannot be negated by blinking, jumping, gaining invisibility, or transforming.
  
• This spell can help to track invisible units. "Shackleshot" can shackle invisible units but it cannot target them. If you believe an invisible unit is behind another enemy you can attempt to shackle them together since you don’t need to be able to see the second unit.

• This spell provides flying vision.

• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• Windranger can negate attack projectiles with the dodge effect of “Windrun”. The attack animation for the projectile must have ended for this spell to dodge successfully (meaning the projectile will be in flight - this spell only dodges attacks, not spells).

Windranger – Focus Fire (does not have a damage type) Tier 2:

• This spell can be cast on structures and Spell Immune units.
  
• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).

Winter Wyvern – Arctic Burn (pure) Tier 1:

• Every effect of this spell affects Spell Immune units.
  
• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• Winter Wyvern is a flying unit when this spell is active.
  
• This spell destroys trees.
  
• This spell can slow and damage siege creeps.
  
• Couriers are slowed and damaged by this spell.

Winter Wyvern – Splinter Blast (magical) Tier 3:

• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• A projectile is generated for Spell Immune enemy units. If a previously Spell Immune enemy unit lost Spell Immunity before the projectile hits the unit, it will take the damage normally.
  
• This spell cannot be negated by blinking, jumping, gaining invisibility, or transforming.
  
• This spell can block creep camp spawns.
  
• This spell can help to track invisible units. Projectiles generated by "Splinter Blast" do damage invisible units and the projectiles generated by this area of effect spell will follow invisible units to their current position.

Winter Wyvern – Cold Embrace (does not have a damage type) Tier 2:

• This spell is an stun (only on allied units).
  
• Every effect of this spell affects Spell Immune units.
  
• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).

• This spell can protect and heal siege creeps.

Winter Wyvern – Winter's Curse (does not have a damage type) Tier 1:

• This spell is a stun and a taunt.
  
• Every effect of this spell affects Spell Immune units.
  
• This spell can be cast on Spell Immune units.
  
• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• This spell has equal priority to Axe's "Berserker’s Call". Whichever hero casts their taunt first (Axe or Winter Wyvern) will last its full duration. If either hero taunted a unit that was already taunted then their taunt will apply to the taunted unit when the first taunt debuff ends if the two taunts did not entirely overlap in duration.
  
• This spell can be used to force enemy units to attack heroes and heroes to attack enemy units. Stationary units such as wards, traps, and mines cannot be taunted.
  
• This spell can taunt siege creeps.
  
• Couriers are taunted by this spell. Since couriers do not have an attack, they will just be disabled by this spell.
  
• This spell is a noteworthy invisibility counter. "Winter's Curse" does force invisible units to attack the targetd unit. In the rare even that this does not remove the unit’s invisibility "Winter's Curse" will at least hold it in a known location.

Witch Doctor (Zharvakko)

Witch Doctor – Paralyzing Cask (magical) Tier 3:

• This spell is a stun.
  
• This spell will bounce from Spell Immune units, but it will not damage or stun them.
  
• This spell cannot target Spell Immune units.

• The heal effect of this area of effect spell will affect Spell Immune units in its radius.
  
• Casting this spell does not interrupt channeled spells or items.
  
• Couriers are healed by this spell.

Witch Doctor – Maledict (magical) Tier 1:

• This spell cannot be dispelled with Spell Immunity or any type of purge (Black King Bar, Manta Style, Diffusal Blade, etc…).
  
• The damage dealt by this spell is based on the difference between an affected unit’s current hit point value and the same value when Maledict was cast. The larger the difference is between the current hit point value and the original value, the more damage the spell will do with each successive tick. This means that a unit that is severely wounded when this spell is cast on it may survive the spell if it takes no additional damage, but that a high hit point unit that is still relatively healthy may die from the spell if it has taken a considerable hit point loss since the debuff was applied.
  
• Burst heals such as Magic Wand charges or Mekansm are extremely effective when attempting to reduce the potential damage over time caused by “Maledict”. Using these heals as quickly as possible is the key to minimize the damage.

Witch Doctor – Death Ward (physical) Tier 2:

• Every effect of this spell affects Spell Immune units.
  
• The damage dealt by this ward is reduced by armor but it is not reduced by damage block.

Wraith King (Ostarion)

• This spell is a stun.
  
• This spell is a noteworthy invisibility counter. "Lightning Bolt" provides flying vision with True Sight of invisible units in radius 750 of the targeted unit or targeted location for 4.5 seconds. Casting this spell on an empty location where you believe an invisible enemy unit may be lurking is the perfect way to reveal them.

Zeus – Thundergod's Wrath (magical) Tier 2:

• This spell is a noteworthy invisibility counter. "Thundergod’s Wrath" provides flying vision with True Sight in radius 900 around each hero struck by a bolt for 3 seconds. If a hero was invisible when Zeus cast "Thundergod’s Wrath" then it will not be damaged, but it will still be revealed with flying vision for 3 seconds.

How to use the Item Sections

Unlike the hero sections of this guide, the item sections are intended to be a comprehensive look at each item in DotA2. Just like the hero sections of this guide however, the rules of damage types, immunities, evasion, invisibility, disables and resistances such as those described in the previous sections can and will be broken at random. Any rules broken in this way are notated as such in the appropriate item’s description. I have notated every item’s cost, purchase locations, available stock, restock time, cooldown, mana cost, cast range, ability to be shared, ability to be disassembled, and list of components. If an item’s section does not list one or more of these parameters then the parameter(s) is not applicable to this item. Any item that can be purchased in the Side Shop or that must be purchased in the Secret Shop are notated as such. Commas separating purchase locations denote multiple possible purchase locations. The use of an upper case "AND" in the purchase locations parameter of an item section indicates that this item will require components from two different types of shop.

Item sections are arranged alphabetically for ease of access. Items with Unique Attack Modifiers are denoted, and any special interactions these items have with other Unique Attack Modifiers are also noted.

Abyssal Blade

Cost: 6750
Purchase Locations: Main Shop AND Secret Shop
Cooldown: 60 Seconds (passive stun has a 2 second cooldown)
Mana Cost: 150
Cast Range: 140
Can be disassembled?: Yes
Components: Skull Basher, Sacred Relic

+ 100 Damage
+ 10 Strength

Active: Stuns a targeted enemy unit / hero / Roshan for 2 seconds. This stun does affect Spell Immune units.

Passive: Gives a 25% melee or 10% ranged chance to stun for 1.4 seconds when attacking enemy units / heroes / Roshan. This ability does affect Spell Immune units.

Notes:

• Illusions do not benefit from this item’s passive ability.
  
• This item cannot be purchased by Slardar, Faceless Void, Spirit Breaker, or Troll Warlord.
  
• This item’s purchase will be declared to all allied players.

Aegis of the Immortal

This item is always dropped from Roshan when he is killed.

Passive: Reincarnates the owner of this item if they die within 5 minutes of picking it up with full HP and mana. They will be reincarnated 5 seconds after they were killed in the same location that they were killed. This item will disappear from the owner’s inventory once it has been used to reincarnate the owner of the item. If the owner of this item does not die within 5 minutes of picking the item up it will disappear from the owner’s inventory. In this event, the owner will then be healed and restored to full mana with a very powerful restoration effect, healing the hero fully over 5 seconds. This effect can be cancelled by attacks from enemy heroes or towers (similar to the healing effect provided by Urn of Shadows). If Roshan respawns before this item is picked up it will disappear without providing any benefit.

Notes:

• Cooldowns are not affected by this item.
  
• Enemy players will be informed of which hero picked up the Aegis of the Immortal.
  
• This item can be denied if it has not yet been picked up by a hero.
  
• This item cannot be dropped, traded, or sold.
  
• This item is destroyed if it is still on the ground when Roshan respawns.
  
• This item is destroyed when Roshan spawns whether it has been picked up or not. This means it is not possible to have more than one Aegis of the Immortal in play at once. It is possible (although probably not wise) to postpone picking up the item to prevent the 5 minute countdown from beginning.

Purchase Locations: Main Shop AND Secret Shop

Cost: 2250
Purchase Locations: Main Shop, Side Shop

Bloodstone

Cost: 4900
Purchase Locations: Secret Shop
Cooldown: 300 Seconds
Components: Soul Booster, Soul Ring, Bloodstone Recipe

+ 500 Health
+ 400 Mana
+ 9 HP Regeneration
+ 200% Mana Regeneration

This item starts with 8 charges. The Bloodstone will gain a charge each time an enemy hero dies in range 1600 of the owner hero or when the owner gets a kill (outside this range).

Active: Instantly kill yourself (triggering the heal that is normally provided passively on death).

Passive: Each charge on this item gives 1 mana regeneration per second. When the bearer dies, allied units in range 1675 will be healed a minimum of 500 hit points. Each charge on the Bloodstone at the time of the bearer’s death will heal for an additional 30 hit points and the Bloodstone will lose a third (0.33) of its charges (rounded down). The amount of unreliable gold that would normally be lost on death is reduced by 25 gold for each charge on the Bloodstone when the bearer died. The respawn time of the bearer is reduced by 4 seconds per charge (also counting total charges before the character died and some were subtracted). While the bearer is dead they gain 1800 day and night vision of the area in which they died. They also continue to gain experience when enemies are killed within range 1600 of their death location.

Notes:

• This item's active ability treats the subsequent death as a deny.
  
• Using this item’s active ability when in possession of an Aegis of the Immortal or when using a hero with a passive ability that will revive the owner (such as Wraith King’s “Reincarnation”) will put the item on cooldown and kill the owner normally. No charges will be expended and no healing will be applied to nearby allies since the hero will be revived shortly.
  
• This item’s passive ability will only function for the highest priority Bloodstone in the hero’s inventory if the hero has multiple Bloodstones (meaning it is a bad idea to have multiple Bloodstones).
  
• This item’s purchase will be declared to all allied players.

• The teleport will automatically target the fountain if the item is double-clicked.
  
• The casting time of Boots of Travel is always 3 seconds, regardless of recent allied teleports of any kind.

• Unlike a Town Portal Scroll, no trees are destroyed by a successful teleport with this item.
  
• This item pings the minimap for all allied players at the target location of the teleport.
  
• Flat movement speed bonuses from multiple pairs of boots do not stack.
  
• The teleport will be canceled if it was targeting an allied creep and that creep is converted or killed during the teleport channel. The cooldown penalty will still apply as if the Boots of Travel had been used.

• When a rune is activated from a bottle (whether manually or automatically) the bottle will be refilled with all 3 charges.
  
• The bottle cannot be dropped or traded when a rune is stored in it.
  
• Holding CTRL before pushing the Bottle’s hotkey will grant a context sensitive cursor that allows you to share bottle charges with allies. Only one charge will be expended at a time. Attempting to share a bottle charge when a rune is stored in the bottle will activate the rune (without sharing a charge with an ally).
  
• This item will be refilled at the fountain, even if it is on the courier. This means that a hero can call the empty courier manually and send their bottle back with the courier to the fountain so that it can be refilled without having to return to base.
  
• Bottles without all 3 charges slow courier movement speed by 30%.

Diffusal Blade

Cost: 3150/3850 (at levels 1/2 respectively)
Purchase Locations: Main Shop
Cooldown: 8 Seconds

+ 20/35 Agility (at levels 1/2 respectively)
+ 6/10 Intelligence (at levels 1/2 respectively)

Whichever one Anti-Mage buys/learns first will be used. Dropping or purchasing the Diffusal Blade with "Mana Break" skilled will make it impossible for Anti-Mage to benefit from this items passive ability.
  
• Melee illusions are granted the passive mana burning ability of Diffusal Blade but ranged illusions are NOT.
  
• Does not affect Spell Immune units (but is able to purge Omniknight's "Repel").

Ethereal units cannot be targeted or damaged by any sort of physical attack, spell, or snare. Ethereal units cannot attack. Ethereal units take 40% extra magical damage. This debuff can be purged.

Notes:

• Shares the same cooldown as Ghost Scepter.
  
• Using a teleport scroll will remove the Ethereal buff from the owner (using Boots of Travel will not).
  
• Becoming Spell Immune will not remove the Ethereal buff from the owner hero or from allied heroes (it will remove it from enemies) when it is caused by Ethereal Blade (unlike when it is caused by Ghost Scepter). This means that it is possible to be both physically and magically immune at the same time (practically invincible) when using Ethereal Blade and Black King Bar together for a short time. Ether Blast must be used before Avatar or Avatar will remove the Ether Blast buff.
  
• Does not affect Spell Immune enemy units.
  
• The Ethereal debuff is applied before the damage is dealt, meaning that it will be amplified by 40%.
  
• This item’s purchase will be declared to all allied players.

[rISO(ITA)]

Unbelievable job...

[Chicken - bring them democracy]

RIP Poormans sheild

[clawz161]

Very nice and detailed guide, needs a few updates which you already know about.

[7A.Calá7]

Nice guide,but you should change some things,for example:
*Remotes mines doesn´t work against blade fury (juggernaut),meanwhile suicide squad,attack! does
*Remotes mines doesn´t block camps anymore

[Caro]

This is perfect, just what I needed, thanks for making this..

[Turbo Potato]

Also, as of 6.82, Denied creeps provide 50% exp, not a flat 36 exp per unit. I get that you're not updating it right now, but thought I'd leave this here.

[Turbo Potato]

Non-hero XP Value List- "Brewmaster's Aghanim's Scepter Fire Level 1 - 196"

Why is this here? It seems redundant.

Also, do "super creeps" that appear after you take one rax give any different exp?

[WhiteHawke]

I apologize to everyone waiting on updates to the guide. I do still plan on making them for 6.85, but I've been very busy with another guide project.

[cytraL skunK]

Beastmasters' roar pierces spell immunity, might want to update

[Banana]

Who would spend their life updating this?
