More-more Warpfire!
 Psyker Build - Warhammer 40k: Darktide 

First things first, this build is not meant to be played melee with the knife, it is mostly a mobility/defensive tool, the star of the show is the Rifthaven Mk II Inferno Force Staff , when dealing with lonely carapace armored the knife absolutely melts them, but otherwise, the flame staff is safer and better
 

      Curios

• Sprint eff for kiting better with the charge attack of the knife and running, 
   
• Toughness for the survivability 

• Block efficiency because I like blocking, but you could change it for gunner resistance or the likes.
   

  
  Weapons

  Catachan mk3 cuz fast, but you could go for duelling sword mk5 with Agile for perma dodges, up to you

  Inferno Force Staff, I REFUSE TO EXPLAIN WHY YOU HEATHENS, warp Nexus cause crits and Empathic Evasion makes you effectively immune to ranged attacks, you'll want to be always at roughly 60-80% for this perk to be active and for the Venting Shriek to blurt out max fire stacks. almost ALWAYS charge 1/3 of the bar and release, better cc and damage this way.
  
  Tip: When you have venting shriek off cooldown and high peril, feel free to charge a full flame and when you inevitably almost explode, use it, free dps and CC
   

  
  MODS

  While not really necessary, seeings hundreds of numbers as you burn a horde away makes my pants moist so for maximing your enjoyment i reccomend some sort of healthbar mods, I personally use Healthbars by raindish ()
