Tech Adept 4 Kastellan Battle Automata

Updated for v2.9.4d
A guide for the tech adept with ranged weapons and up to 4 Kastelan bots

Important Note :

In this guide i do not tell you how to spend all 111 points. Some are noted as optional or not mentioned at all. Feel free to add this points wherever you wish !

Basics

As described we want to use ranged weapons.

This will be the Radium Carbine Beta

and any Kind of alpha weapon for summoning.

As armour we will take the Electroid Shielding.


For the belt the Technomarty Girdle.


This gives us 2 attacks with the weapon, 3 slots for constructs, and a life leech ability for all constructs in a radius around us.

Radium Carbine Beta gives us two attacks, "Single Shot" which is armour breaking, has a knockdown and adds a poison effect plus it tags the target as primary target for your constructs. "Full Auto" which just does what it's name implies and lets you fire the whole clip with a light spread , also adding a poison effect.

totally optional but i did so you might wanna try :

Construct Defense

This will get you "Galvanic Booster", a whopping 1% HP regeneration per second for constructs !

Whatever costructs you have, they will regenerate fast enough to make them very durable.

other notable Bonuses :

- Constructs are immune to DoTs

- Constructs are immune to knockdown

- damage reduction to constructs

- 5% supreme damage reduction for Kastellan robots
- 500 H P shield for constructs
- 5% all resists for constructs
- several HP bonuses for constructs / Kastelan robots
- 25% damage to you are transfered to your constructs, their damage reduction applies to that damage


Get the perk "Archeotech Constructs". It will reduce the amount of Data - flux you have to reserve for upcalled contructs.

Important Stats

Attributes
Mindlink for all your Data-flux needs (25 when possible)
Bionics 20 for HP/Suppression for you and benefits for constructs + damage mitigation for you
Logic 20 for Damage and Movement sopeed for you and the Kastellans, those things are SLOW

Gear
What you need on your gear is

1) + x Data - flux
2) - x % Data - flux Cost

These stats can be found on all 3 implants (Neural/Eye/Main)

The first stat can be found on the Purity seal too

Useful stats are

+ hp per hit
+ hp per hit for constructs
+ supression per hit
+ poison dmg
hp regeneration
supression regeneration

Pro Tip :
If you don't get enough -x% Data-flux Cost it is entirely possible that you won't be able to use the life leech of your armour !

Rule of thumb seems to be that you need around - 25% Data-flux Cost to use the life leech of your armor, depending on your Data-flux Cost.

Example : For this calculation the Data-flux total will be 210 (173 Reserve + 37 free to use) the heal at the moment of this calculation costs 50 Data-flux.

1% would be 0,5 Data Flux. 37 Data-flux would be 26 % rounded.

So two items with - 13% Data-flux Cost should be enough in this example.

Addendum : As you might have seen on the new picts i got some Escalation shards to drop Data-Flux cost even more ! If you have access to these shards, use em. helps tremendously !

Health

If you don't survive the battle it doesn't matter if your constructs do.


"Field Surgery" .
This little gem resets your Inoculator cooldown when you enter the exposed state, i.e. when you are under 25% hp.

This allows you to survive much easier even if you get hit hard and need a bit of time to hide behind your constructs.

Pro Tip :
If you still feel fragile add 2 points in the Defense skill tree to get "Skeletal Padding" which adds 20% damage reduction from armour. 2 more points do get you "Shock Dampening" which adds 2% damage reduction

Construct Offense

This Tree gets you offensive and defensive Bonuses for all Constructs and specific ones for the Kastelans. Notable ones are

- life drain
- shield drain
- +5 % HP gained on kill
- +1 % Hp on hit
- supression damage bonus
- several damage bonuses

Construct Ability

This tree gets us"Cybernetic Canticle" which gives us 30% duration to all summons kills and 5% less reserve cost for constructs.

Other notable bonuses :

- attack speed bonuses
- movement speed bonuses
- AoE Shock ability + 20% cooldown reduction for it
- Explosion for disabled Kastellans
- Data Flux on kill for constructs depending on the enemy killed 1/2/3, more for tougher enemies

Construct Specialisation

This will take a while because we need 14 points for this skill tree.

Our ultimate goal is the main ability in the middle (or at the end) of this skill tree "Voltaic Communion"

which gives us another -20% Data-flux reserve.



On the way to the middle we will get

- 4 times -5% Data Flux cost for summoning skills (20% total)

- 3 times 3 % Area of effect for Constructs

- 4 times 5% Cooldown reduction to summoning skills (useless afaik as we do not summon the Kastelans)

- 25% Damage Bonus for Area of Effect for Constructs agains Villain Elite Comannder and Boss enemies

Perks

As mentioned above the first Perk should be " Archeotech Constructs"

The second perk should be "Sanctified Data Wafers" that adds 15 % damage bonus for each Kastellan robot (45%)

Addendum : If using Alpha summoning (you really should) that will be 60% !

The third Perk should be "Defensor Augmetics" that adds 0,25% damage reduction per Reserve Percentage for the Tech Adept and the Constructs


That means for me i have 272 Data-Flux, 190 are reserve so roughly 70% Reserve multiplied by 0,25

17 Damage reduction rounded down for me and my Constructs.

Addendum : After getting - 30% Data Reserve cost i am at the following numbers :

229 Data flux, 139 reserve, 90 free to use that would be 15% damage reduction rounded down for me and the constructs.

If you are more concerned about yourself i would say choose : " Blessing of Saint Victorious" that doesn't let you loose more than 30% hp from one hit. Good at +7 and above !!!

Modules

Modules are bluntly said, equipment for your constructs.
Yes, that means you have to get equipment for your constructs too.
When you are reading this you should have 3 equipment slots and 2 weapon slots to fill.

The most important Modules are :

- Endurance + X Max HP
- Offensor X % Damage for the construct


The constructs use the power fists for area damage (anti horde) and the Phospor cannon for ranged attacks


As with your own equip, try to modify the stats of the modules to something useful.

That would be

Power Fist

- + Melee damage
- Damage reduction
- any resistance
- Hp regeneration

Phospor Cannon

- + Ranged damage
- + Heat damage
- Damage reduction

legendary Prefixes highly recommended
- immune to stun
- immune to knockback
- supreme damage reduction

If your Kastellans are stunned they can not fight back, that is avoidable ! Even if they are now packed with HP and sturdy you do not wanna loose them cause they are chain stunned by some mobs while everyone else goes to town with them

Morality

If you do choose where to go by roleplay read no further.

Everyone else ? Tag along...

at this point it simply doesn't matter. The only point going Radical was the perk which i do not use anymore cause of the change from heal over time to attack speed buff.

Psalm Code Doctrines

There is one Psalm Code Doctrine that you should add as fast as you can, AFTER you upgraded your forge to get the Psalms back if you wish to.

Emanatus Psalm + Galvanic Psalm + Volkite Psalm = +100% Minion HP
If you can use it twice do so as soon as possible !

The second one you should get is :

Phosphoenic Psalm + Binharic Psalm + Volkite Psalm + Terminus Psalm = +125% Heat Damage
Third one :

Haemo-drain Psalm + Animus Psalm + Aegis Psalm + Uncreator Psalm = +125% Physical Damage

Advice :
Two-Handed weapons: 1-6 sockets
Armor: 1-6 sockets
Main Implant: 1-3 sockets
Inoculator: 1-3 sockets
Belt: 1-2 sockets

That means Doctrine two and three can be used in Weapons and Armor only. That leaves Main Implant and Inoculator for Doctrine 1 (x2 if possible).

Final Words

It took me almost 2 years to get here, so i am really excited and happy that i made it so far.

I hope you have fun with this guide, despite me taking so long to finalize it. If you do, please leave a comment, rate it, or tell everyone you know playing this game about it.

Addendum

As some of you may know i stumbled upon a mechanic i called alpha summoning in one of my other guides. I was curious if i could do that with the Kastelan build to.

Well the answer is YES.

So what does this mean and do ?

- You grab an Alpha weapon of any kind.
- You put it in your first weapon slot .
- If you start a mission you should now summon 4 Kastelan robots
- switch to weapon slot 2 for your optimized weapon
- the 4th Kastelan STAYS

IMPORTANT
This does work ONLY if you have enough stats like :

- data-flux cost (-19%Neutral Implant, -12% escalation shards in armour for me)
- reduced data-flux reserve ( 2 x 15% armor/rifle for me)

If your stats ain't high enough it might be possible to summon 4 Kastelans but not use "Overdrive" or the "Redirect Damage" of our armour !

Rework after 2.9.4d

I did a test run with the non optimized gear.

Result :



ah the red skull ? Before you ask ... i came to close to a flamer turret. silly me

[Shoark]

more updates/rewriting

[Shoark]

This is by no means a speed farm build, but it will get you through +10 or more with the right gear !

[Shoark]

i dunno when they fixed the Kastellans but i am happy right now. updating guide !

[Romney]

I also use 1 melee with a flame thrower so maybe it would work I also use heat weapons. I am liking it.

[Shoark]

@Romney you can do that, depends : do they use heat weapons only ? I have a melee one mixed in so that one would be left out by that doctrine

[Romney]

About doctrine +125% Heat Damage. Affects Constructs as well." wouldn't it be better?

[Shoark]

you're welcome

[Shmitty85]

Thank for the reply @shoark

[Shoark]

@shmitty85 nah does not matter anymore

[Shmitty85]

What starting expertise should we pick, or does it not matter?
