Inaros: The Lazy Tank Build
By ThePHiLsTeR [¬º-°]¬
This tank build is so lazy. It requires nothing but items to survive.

This Guide Is For Lazy People
If you're not lazy, then why are you reading this?
How Inaros Tanks
Inaros has the highest base health points of all warframes at 2200. With mods, we will bring that up to an insane amount, add some damage mitigation items, and sources of health regen and VIOLA, you have the laziest tank in the game. You basically do next to nothing to survive. All the items will do the work for you. The key is to have sources of regen that heal based on % health to take advantage of Inaros' insane health pool. With high damage mitigation, the goal is to have health regen equal or greater than damage taken.
Sources Of Damage Mitigation

Damage Reduction = Armor / ( Armor + 300)


This mod will be vital. The damage mitigation stacks multiplicatively with damage mitigation from armor. For example, 300 armor gives 50% damage mitigation. Adaptation provides 90% damage reduction to the remaining 50% damage for a total of 95.5% damage mitigation.

Arcane Guardian

  • 20% chance on being damaged to receive +600 armor for 20 seconds
  • Can be stacked for a total of +1200 armor for 20 seconds
  • Proc's consistently
Sources Of Percent-Based Health Regen
Arcane Grace

  • 6% chance on being damaged to regen 4% health per second for 6 seconds
  • Stacks for a total of 8% health regen per second
  • Proc's consistently
What Is Effective Health (EHP)?
Effective Health is an effective way of calculating survivability and provides a precise number. It is a alternative way of looking at survivability from an increase of effective health rather than a damage mitigation standpoint. You can think of it as total damage an enemy will have to deal to you before you die. For example a warframe with 1000 health and 50% damage mitigation from armor will have an effective health of 2000.

Effective Health Calculation
Effective Health = Shield + ( Health ) / ( 1 - Damage Reduction )
Build 1
This is in my opinion the optimal build with hand spring being optional and only there to help with annoying knockdowns from enemies in Orb Vallis. Corrosive Projection can be swapped for Physique (+90% health).
  • 8635 Health
  • 585 Armor
  • 96.6% damage mitigation from armor and Adaptation
  • 253,970 EHP

Build 2
The first build is really expensive on endo and credits. If you'd like to opt out of that, this build will be cheaper. Again hand spring is optional and is only there for knockdown recovery against enemies in Orb Vallis. Rolling Guard is also optional, but is very nice. The 3 second invincibility will allow pure health regen for those 3 seconds. Corrosive Projection can be swapped for Physique (+90% health).
  • 6270 Health
  • 600 Armor
  • 96.67% damage mitigation from armor and Adaptation
  • 188,288 EHP

Valkyr Prime Comparisons
Seems people want to apply this idea to Valkyr. Here are stat comparisons with similar builds.

Build 1
  • 1470 Health
  • 260 Shield
  • 1755 Armor
  • 98.5% damage mitigation from armor and Adaptation
  • 100,695 EHP

Other sources of health regen will clearly be superior.

Build 2
  • 1040 Health
  • 210 Shield
  • 1800 Armor
  • 98.6% damage mitigation from armor and Adaptation
  • 74,900 EHP

Other sources of health regen will clearly be superior.
Test Results
Profit-Taker Orb Fight
I tested both builds 1 and 2 equipped with 1 Arcane Grace and 1 Arcane Guardian against the Orb Spider and allowed the Corpus enemies to deploy 4 Reinforcement Beacans. Both builds held up maintaining full health throughout.

Arcane Guardian VS Arcane Grace
I tested which arcane combination would be best using a level 160 Heavy Gunner. Here's what I found:
  • 2 Arcane Guardians are best if you plan on using other sources of health regen besides Arcane Grace.
  • 2 Arcane Graces provided just about the same amount of survivability as 1 Arcane Grace and 1 Arcane Guardian. Because Arcane Guardian is easier to obtain, 1 Arcane Grace and 1 Arcane Guardian is probably the best combination.
The Lazy Tank setup cannot replace the top dog, Rhino, for this game mode. With each point, the player receives a Financial Stress Debuff which lowers health and shield. At 15 points, Inaros's health goes down to 340 with Build 1.
Alternate Sources Of Health Regen
Vazarin's Protective Dash
Allies (including your own warframe) hit by void dash are healed for 60% total health over 5 seconds (12% health per second)

Magus Repair

  • On Void mode, heal your warframe and allies within 20m for 10% of their health per second
  • Stacks for a total of 20% health regen per second

Arcane Victory

  • Provides a 50% chance to gain 2% health regeneration per second for 6 seconds upon achieving a head shot kill
  • Stacks for a maximum of 4% health regeneration per second

Magus Elevate

  • Grants a 75% chance to restore 200 health to a Warframe after transferring into it
  • Stacks and has a chance to heal up to 400 health per transfer


  • Heals 12% of total health over 4 seconds
  • Has a 15 second cooldown
  • 0.63% health regen per second

Hunter Recovery

  • Heals the player for 30% of the damage the beast companion deals


  • Winds of Purity cannot be equipped on Afuris or Dex Furis


  • Heals for 5% of damage dealt on critical hit.


  • Heals for 10% of damage dealt on headshot

Life Strike

  • Can be equipped on any melee weapon. Steals life on channeled strike

Healing Return

  • Heals the user the stated amount for each status effect currently afflicting the target. For example, if a target is afflicted with slash, toxin, and cold, each melee strike will heal for 11x3 or 33.
  • Does NOT provide any healing if your attack, despite proccing a Status Effect on the attack (for example, with 100% status chance), kills the target instantly on the first attack.

😮 good stuff 🙂

And I don't know how effective this is, but the Basmu (https://warframe.fandom.com/wiki/Basmu) can also heal you. According to the wiki:

"Fully depleting the battery produces three 10-meter pulses that deals up to 10 True damage, staggers nearby enemies and heals the user's health by 10x the damage done to each enemy per pulse."

Paris Prime also has this: https://warframe.fandom.com/wiki/Bhisaj-Bal

Not bad, I'd say, for a Status-focused build. And Bow-lovers might prefer it over some of the other options.

Another great alternative healing option for Nikana-lovers: https://warframe.fandom.com/wiki/Amalgam_Daikyu_Target_Acquired

You equip a Daikyu that has the "Amalgam Daikyu Target Acquired" mod installed. Then you (with a full rank "Amalgam Daikyu Target Acquired") have 3% Life Steal on Nikanas.

Luckily Nikanas are my favourite weapon type.

I don't think you mentioned that when inaros does a finisher he heals 20% of his maximum health. that can be a really useful thing to know.
ThePHiLsTeR [¬º-°]¬  [author] Jul 17, 2019 @ 10:51am 
Im assuming your referring to the EHP charts? I'm just listing the number of arcane you installed. If you installed 1 arcane then you look at 1 arcane stats. 2 arcane means you equipped 2 arcanes.
Daxank Jul 17, 2019 @ 10:47am 
what do the 1 and 2 next to the arcanes are supposed to indicate?
The amount equipped ? Do we assume they're also max level ?
MeoWeoMeow Jan 17, 2019 @ 11:07pm 
oh I see, thanks i will swap back to my old primed vigor, very good advice.
ThePHiLsTeR [¬º-°]¬  [author] Jan 17, 2019 @ 3:07am 
Once you reach 1 health*
ThePHiLsTeR [¬º-°]¬  [author] Jan 17, 2019 @ 2:07am 
Well primed vigor gives +health. We're essentially stacking health for maximum %based health regen.

Problem with quick thinking is that, first Inaros has a small energy pool. Second, once you ready 1 health, adaptation no longer applies its +90% damage reduction. Another problem with Quick Thinking (on Inaros I mean not other warframes), is that if the lethal damage is too large it'll outright bypass quick thinking. In this case it is easy to do with Inaros' small energy pool.

It's best to take advantage of strengths. In this case it is health not energy pool.
