Battlescruncher 30000AD
 Psyker Build - Warhammer 40k: Darktide 

Intended for high havocs.

Elects for voidblast to facilitate specialist deletion and ranged suppression that inferno can suffer with, while providing more consistent AoE than voidstrike.

Takes soulblaze nodes to keep crit chance high with Souldrinker and to help continuously proc Kinetic Flayer.

Sacrifices some damage in exchange for peril reduction / quell speed with Battle Meditation  and Solidity to compensate for the combination of havoc quell reduction (capping at 85% reduced quell rate at H30). Those are the build's flex nodes, but having constant uptime peril reduction and/or quell assist is very much worth taking for staff use with Warp Ghost imo.

Talent Variations: Damage/Crits vs CDR

Increasing shield uptime is very helpful if your comp lacks another means of turning off shooters (e.g. smokes or Voltaic Emitter). 

Aura: If feel like you only need a marginal CDR improvement, you can swap the aura to Seer's Presence.  You lose Prescience's synergy with Disrupt Destiny, but crit chance is still kept reasonably high without the aura's bonus through the combination of the staff perks and blessings, Souldrinker, and passive quelling reduction from Warp Ghost.

Keystone: For a more dramatic CDR improvement in exchange for loss of melee and top-end damage output, can swap keystone to Warp Siphon, ideally up to In Fire Reborn. 

• One non-keystone node needs to be freed up for the switch - as noted earlier, suggest Battle Meditation or Solidity . 
• I prefer getting to Warp Siphon via Penetration of the Soul to maximize damage and get the most out of Warp Ghost's toughness bonus.

Shriek Variation

If you want to up your overall damage and your comp doesn't need a shield, take Venting Shriek . I think it works best with Warp Siphon so you can really spam the ability - therefore, no longer need the peril / quelling nodes since shriek will make peril more controllable and even more desirable.

• Swap Telekine Shield for Venting Shriek up to Creeping Flames 
• Remove Battle Meditation 
• Swap Disrupt Destiny for Warp Siphon up to In Fire Reborn , via Penetration of the Soul 
• Swap Solidity for Peril Equilibrium 
• Same weapon and curio setup
  • Can maaaaybe take Warp Flurry or Rending Shockwave instead of Blazing Spirit on the staff now that you have another instant soulblaze source, but in my experience not taking Blazing Spirit results in a considerably lower Souldrinker uptime and in lower horde damage overall.
• Any aura works fine. Seer's Presence not really necessary since uptime on shriek will be nuts with all of your soulblaze procs.
