Psyker - I am Forever Blowing Bub-bles! - Pyro Staff Bubbler
 Psyker Build - Warhammer 40k: Darktide 

Bubble version of : https://darktide.gameslantern.com/builds/9f6e57c2-5145-4ef2-9c0e-832d86f51590/psyker-meet-the-pyro-final
-> Pyro havoc build - venting shriek ability
 

changes:-

1)  Ability : Venting Shriek [to] Telekine Shield (bubble variant)
>> impact >> : you lose the ability to regularly stagger back Ogryn sized mobs (flame staff LMB staggers up to, and including, Maulers only)

2) Weapon (MELEE): Duelling sword -> Deimos Force sword 
>> why? >> : see impact from [1], the force sword offers Force Push to close this gap, but you lose mobility and eye-poking effectiveness. Added block blessing to add a bit more block-ability due to reduction in mobility

3) Weapon (RANGED): Increased 'warp resistance' to 60% from my previous wep of 35%, since we don't have access to infinite peril management with [Venting Shriek] (lucked out on super low brunt item, difficult to control lowest achievable warp resistance on staff)

4) Talents : We're not required to take 'One with the warp' to reach Shriek ability, and at Havoc the PSYKER is eating major shit on any heavy attack from a lowly pox-walker. You can address needling damage from trashmob gunners with curios, >> Everything Else: GIT GUD & don't get hit <<. I've Added [Anticipation] instead for +1 dodge and 50% dodging effectiveness time talent to give more flexibility while 'in the mixer' with unstaggered melee elite packs (from lack of Venting Shriek option).

Other Notes 

(if here directly, vs. previously viewing above linked build) 
 "I've put more crit on the talent tree as it's piss low at a base, blessings and modifiers on the staff are non-negotiable IMO (for peak soulflame DoT output, which is your primary job here, bubble is a close second); therefore you NEED to find a reasonable amount of crit on the tree to proc other talents and more reliably break DoT cap from staff."
