Faithful Martyr - Stunstorm, Fury of the Faithful, Martyrdom
 Zealot Build - Warhammer 40k: Darktide 

*This build is in the concept phase.*

The goal of this build is to become nearly unstoppable with our Crucis Mk II Thunder Hammer.

Main Build - Talents
Second Wind is insanely helpful as you get toughness replenishment for doing something you'll be doing most of the time anyway. Purge the Unclean is there to help beat down mutants and monstrosities. Vicious Offering works nicely with the relentless heavies of the hammer, and Bleed for the Emperor combined with max wounds will give you toughness damage reduction on most hits. Stunstorm Grenade as our blitz gives us additional help for crowds. Duellist pops off as often as Second Wind for a big damage boost. I might swap out Desperation for a melee damage node or something, but I figure I'll try it and see if it comes in handy; use that point however you prefer. Fury of the Faithful will help us easily close distance while granting +25% damage and a guaranteed crit, allowing us to take big chunks out of monstrosities. Punishment will be invaluable as most of the time we'll be spamming heavies and Uninterruptible will let us do so without being staggered. Martyr's Purpose only applies to health damage and not toughness damage, making it only useful in an impending death scenario; therefore I choose to skip it to use the point elsewhere. The extra wounds from Faith's Fortitude are necessary for Martyrdom, and both keystone modifiers will grant us up to 45.5% toughness damage reduction and +28% attack speed; you can swap out either modifier if you find them unnecessary.

Primary - Crucis Mk II Thunder Hammer 
With a more consistent moveset over its counterpart, the Crucis Mk II Thunder Hammer is the better choice for our devastating damage-dealer. Relentless heavy attacks allow us to dish out plenty of damage and stagger at the same time to keep most melee enemies from getting too close. Ogryn are quickly dispatched with a charged heavy boosted by Thrust, and Slaughterer will be active most of the time to help us cleave through crowds. I take unyielding damage for monstrosities and Ogryn, and flak damage for general elites.

Secondary - Zarona Mk IIa Quickdraw Stub Revolver 
The secondary is up to preference, I tend to perform best overall with the Zarona Mk IIa Quickdraw Stub Revolver. High damage, accurate, ADS for long range, plus decent piercing to tear through enemies in a crowd. Surgical and Hand-Cannon are the standard blessings for this weapon. I bring unyielding damage for a ranged solution to Ogryn and crit chance to help with Hand-Cannon, though both perks could be subject to change.

Curios - x3 Wound - Cooldown Reduction, Toughness, Gunner Resistance
More wounds for more Martyrdom. My perks are the same as all my other builds: cooldown reduction is always nice as our ability is our most useful tool, extra toughness is always helpful, and gunner resistance covers the most numerous and peskiest enemies.
