The Sanctified Shiv - Stealth Assassin Build
 Zealot Build - Warhammer 40k: Darktide 

Stealth Zealot Build - "Prayer may cleanse the soul, but pain cleanses the body."

The cult that raised him never once taught him to pray for mercy, only to deliver it, to whoever needed it the least...

• The Blessed Knife - For backstab and general horde clear through bleed stacks - Blinded by Blood, Flesh Tearer paired with the high crit rate allows for hive scum level DOT kills on mixed hordes. No last rites, the tenets don't call for a witness. I generally only use heaves for the knife hence Vicious Offering, Unfaltering might seem tempting but heavies on the knife barely slow you so its not worth it. 
• Pious Boltgun - Saved for the heavy armor packs, toss a throwing knife mid animation to skip the lengthy swap. Shattering Impact allows for effective crusher damage and Puncture for boss damage. Mainly for dire straits use blades for the occassional gunner. Out of Pocket also ensures we very rarely need to reload. For when the quiet approach isn't enough, the transition to open violence is instant and you better have spare ammo!
• Last Rites" Stealth Stance - Master-Crafted Shroudfield and Time to Kill allow for easy one tap backstabs on lethal threats such as crushers and bulwarks, use for this, a get out of jail free card and to revive the team!  
• Blazing Piety -  For more consistent knife DOT.  Stalwart paired with Invigorating Revelation makes you a very safe even in a pack of Crushers, armed with nothing but a fancy shiv and conviction.
