Tooya's Martyrdom Zealot
 Zealot Build - Warhammer 40k: Darktide 

Martyrdom Built for Zealot. Works with pretty much any weapon but a few options to consider:

Talents

Duellist vs Purge the Unclean -> if running a high finesse weapon take Duellist, if not swap for Purge the Unclean.

Blitz is dealer's choice, I run Blades of Faith for convenience, but all are viable with Stunstorm Grenade being the best alternative unless you have something with Uncanny Strike to build stacks for Immolation Grenade. If running Flamer or Boltgun, take Blades of Faith for the animation cancel.

Desperation vs Against the Odds -> if running a weapon with more single target damage (such as Dueling Sword or Combat Axe) take Desperation, for high cleave weapons like Heavy Eviscerator or Relic Blade take Against the Odds as they get the most benefit from the extra cleave. Thunder Hammer works will with either, so just take whichever compliments your build (for example if running Flamer, I would take Desperation vs Against the Odds if running a Revolver). Note: taking Against the Odds does require the Holy Revenant point tax, so something to consider. When I don't run Holy Revenant + Against the Odds, I put the spare point into Restorative Verses or either Punish Impiety or Riposte depending on weapon choice (for example, I use push attacks a lot for Eviscerator and Relic Blade to reset attack chains thus would bring Punish Impiety vs Dueling sword where I dodge more and would take Riposte.)

Curios

x2 17% Toughness and x1 +3 Stamina is the best. Always take the +4% Cooldown Reduction. The rest are up to you. I recommend +5% toughness on all and at least one stamina regen. If you have not mastered dodge sliding, would recommend one gunner resist as well.
