Combustion Rupture
 Psyker Build - Warhammer 40k: Darktide 

This is just a really fun inferno(previously purgatus) build I made. You use the inferno staff when necessary but it's mostly about perilous combustion brain rupture spam on elites.. the regen of creeping flames is nuts when you're just chain reaction killing elites.. use the staff to debuff and then combo cast inferno.. REALLY fun build.. brain dead and not good for carrying teams but fun.. if you have a compentent team.. it's an amazing build.. but I mean.. that's the state of inferno in general. Again we use toughness regen speed because you don't need resolve in this build and you have tons of toughness regen.. so the bar moves fast.. we keep agile in this build instead of relentless strikes because.. with constant brain ruptures and double debuff you really don't need as much help with armour and this isn't a havoc build.. it's purgatus in auric.. unlike most purg builds.. this one actually plays fast.. agile let's you zip through the map quickly and keep up with the team and brain rupturing with perilous and double debuff goes brrrr! again.. wildfire is redundant.. you have creeping flames + perilous and a fucking inferno staff.. your staff is the spread.. pretty much the rule goes.. you only need wildfire in plague builds.. you need it when your soulblaze spread is tied to crit'ing on a weapon.. since inferno just is soulblaze.. you don't need this shit.
