Unkillable Servospam Supportank
 Skitarii Build - Warhammer 40k: Darktide 

Spam servo skull to keep all your buffs up. You never need to actually use your gun since the servo skull counts for ranged kills for Hybrid Combat Covenant, Superior Defence Engrams, Threat Detection Imperative, and Galvanic Marking Array. Don't sleep on the Devil's Claw, with all the buffs we're maintaining from our servo skull and crit chance from being at 0 charges all the time with Last Stand Relay, this thing shreds hordes and crushers like they're paper. Might look into swapping phosphor pistol for a braced autogun specifically for suppressing loads of normal gunners, since the servo skull struggles a bit if you have nothing to ping. With how much toughness we are constantly regenerating, plus the almost complete negation of corruption damage, this is probably the tankiest skitarii build possible. If you find yourself not doing enough damage, make sure you are spamming the servo skull, or if there is nothing to ping, use your ability. You need to be at 0 charges 100% of the time. If you are confident in your dodging abilities, you can swap Power Overload for Flensing Protocols, however this costs an extra talent point, as you will want Servo-Sinew Surge and Honed Dissector. I prefer Power Overload as it doesn't lose effect when you get in hairy situations, and I enjoy completely ignoring tox gas, which would eat up Flensing Protocols stacks very fast.

UPDATE 7/15: Took corruption resist off curio due to diminishing returns. I run gunner resist, but other good picks would be stamina regen or revive speed.

UPDATE 7/27: Removed Power Overflow and Sureshot Cogitator Sync in favor of Retribution Conduit and Overcharge Transfer Lattice (this is more of a flex node, but I find it useful for packs of ragers, feel free to sub in whatever instead if you wish)
