Big Dick Psyker [BDP]-Auric/Maelstrom v2
 Psyker Build - Warhammer 40k: Darktide 

Maximizing damage potential on Psyker. WIP.

Blaze Force Sword or Dueling Sword is fine, pick your poison, but deflector is probably a good "oh shit I'm out of position" tool.  Blaze let's you special + dodge mutants as they run by to 1-hit-ko them (probably need 370+ item rating blaze with high tier blessings).

Trauma staff is the throat goat. Run void if you're scared of reaching your true potential (but void helps handle ranged specialists a bit better then trauma, so run void if you don't have a veteran in the party or some other person managing specials at range). Run warp flurry and Rending Shockwave (especially if you struggle against carapace) or Warp Nexus.

Lots of peril management. Kill to reduce peril, purge to reduce peril, kill to reduce purge and purge again. Become the big swinging dick you always dreamed of.

Skip smite, it's a handicap on maelstrom (why stun when you can be DPSing, be mobile, and blow up specialists with your big dick energy). Ventilation purge let's you reset staff for more DPS and cooldown reduction keeps it up.

Brain Burst + Kinetic Resonance makes you automatic-brain-burst-fucking-machine and you have amazing peril management built in to keep you alive.

Curios, focus on cooldown reduction to keep your hip hinges well-oiled for maximum potential, toughness, and anti-sniper (or pick whatever you struggle against).

OPTIMIZATIONS:

-Empathic Evasion and Kinetic Deflection can be swapped in to increase survivability. Same goes for toughness boost.

-Seer's Presence can be swapped for Kinetic Presence for slightly more damage but cooldown reduction is going to be better

-Switching between Brain Rupture and Assail is easy. With Assail you gain mobility while quelling but lose ability cooldown. Pick up assail if you need more tools to deal with range.
