Moth's Manic Pyro
 Psyker Build - Warhammer 40k: Darktide 

     1. Rifthaven Mk II Inferno Force Staff and Assail  are your main weapons. The staff inflicts brittleness on large enemies, supporting your allies. Assail with Ethereal Shards is fantastic at clearing groups, or it can be aimed to eliminate weaker ranged enemies (i.e. Scab Sniper )'

     2. Maccabian Mk IV Duelling Sword is meant to deal with larger enemies. just keep charging heavy attacks to their head and even the mighty Crusher falls. The melee is up to user discretion, i just prefer the duelling sword for large enemies.

     3. Scrier's Gaze is a weird and messy ability. the core is this; constantly generate peril but gain damage and toughness buffs the longer you remain in the ability. due to the already low cooldown and curio perks, you basically have gaze the entire game. activate it, spam Assail or Rifthaven Mk II Inferno Force Staff, quell peril, repeat.

     4. Disrupt Destiny marks enemies, killing them gives you toughness and movement speed buffs, that's it. during waves the amount of enemies marked combined with Scrier's Gaze gives you enough toughness to be effectively immortal'

     5. Boss dps isn't great on this build, the best thing you can do is proc Penetrating Flame  to debuff them for allies to get good damage in. In the worst case scenario, the Maccabian Mk IV Duelling Sword does solid single target damage, and psykers are fairly agile so you could duck and weave bosses.

use scryers gaze, spam attacks, quell peril, rinse and repeat
