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

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

• Tac axe light spam is kinda busted on a crit build as it can even churn through armour. I recommend an auto swing mod if on PC, mix in defensive pushes to trigger Punish Impiety for stupid attack speed. rapid light attacks allows for quick stacking of Scourge. i find Backstabber great to support teamamates after a Chorus of Spiritual Fortitude and all em crushers and maulers are on the floor and Against the Odds for the Axes limited cleave.
• Flamer for mass armored hordes and most importantly bosses - use knives to easily swap to flamer and for ranged targets. 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. 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
• Chorus of Spiritual Fortitude is great when the crushers get close to give your time to kill them. also great for bosses and a counter to em spicy poxbursters at the moment.
