 Psyker Build - Warhammer 40k: Darktide 

Build is by no means perfect or fully optimized. It works in Auric but ofc you can find way better builds out there. This is just something i've been messing around with for fun (Zenpally from Youtube told me to post it in here. Go check him out)

General goal is to stay on top of Specialists and kill them before they have an impact. Snipers, granade dudes, trappers etc are all 1 shots with brain rupture. mutants are for the most part 1 shots aswell with the sword (given you actually dodge and stab them at the same time). Crushers, Maulers, Bulwarks and Reapers are 2-3 shots with BR.

Reason for Combat ability Regen on Curios are simply to help reduce the cooldown on Telekine Shield (2 charges ofc) so that you can utilize Kinetic Resonance as much as possible and it offers your team alot of protection so that they don't feel forced to push in when under heavy fire.  (+ you wish you had a shield when getting charged by 20 hounds or mutants lol)

My Curios are more or less just what I had laying around. Just put on a bit of both toughness and Health for the sake of being slightly less of a glass cannon (theres always that one enemy behind you nobody noticed who bonks you hard)

Stamina Curio is simply because it's nice to have just a bit more for a sticky situation.

Duelling sword= easy mutant kills and decent anti Carapace (headshots only ofc)
Purg staff for horde clear/burning. Does very well against hordes and flak armor. 

You are a Psyker after all which means you are squishy. Stay away from melee as much as possible and be that player who deals with enemy ranged units (Specialists are first prio followed by gunners)
