The Seraph of Flame - Righteous Purgation Build
 Zealot Build - Warhammer 40k: Darktide 

Crit Focused support build - "Lend me your wrath, lend me your hate, lend me your fire!" — Saint Celestine

She's died in this war more times than most soldiers have fought in it, and every time, she gets back up.

• Seraphs Tac Axe - Light spam is kinda busted on a crit build as it can even churn through armour when paired with Fury of the Faithful. I recommend an auto swing mod if on PC, mix in defensive pushes to trigger Punish Impiety then just light spam most threats with the occasional specal for the stagger. Scourge will proc like crazy allowing you to bleed enemies and keep cooldown super low.
• Fury of the Faithful - Here to get us moving like an avanging angel through charges and attack speed. we can even churn through armour  quite well thanks to the rending. Zealous Pilgrim and Fire and Fury also allow for extra fire as a seraph demands!
• Purgatus Flamer -  For the unwashed mass armored hordes and most importantly bosses. Primary attack is great for stagger with the secondary mode for the rest. Burning away corruption is as much doctrine as it is tactic with this build. Anoint in Blood fits perfectly with this aggressive style so get close to burn them bosses with Purifying Hatred. Everlasting Flame may seem temping but the lack of total ammo on the flamer makes it overkill, more debufs and damage is preferred to having to do a reload occasionally. great for mixed hordes with crushers due to Penetrating Flame.
• Purgation Grenades  - Honestly knives would be a better pick with the flamer but hey more fire makes the seraph a happy gall
