Benediction, Piety and the Fury of the Faithful [Update 1.13]
 Zealot Build - Warhammer 40k: Darktide 

Primer Coming EVENTUALLY!

Havoc 40 modifier -> Total Toughness = || Total Health  = 

Defense: B+ (High survivability)

[6 sources of consistent toughness generation] 

[Up to 9.5% toughness generation per second/12.5% with Prime Target active]

[Melee stun immunity and movement speed when hit via Thy Wrath be Swift] 

[20-40 flat toughness generation via the new @Risen talent]

[+25% TDR base +25% more with Stalwart]

Offense: A- (Good melee power with a ranged support side arm for picking off targets)

[Great dueling potential into Monsters and Captains benefiting from dots during duels] 

[Decent Horde clear and Elite fighting power] [Aims for coverage into all enemy types]

[Sidearm helps stack Blazing Piety with crits, and has synergy in kit with Scourge and Blinded by Blood]

[Constant 25% - 90% melee damage bonus]

[+20% damage into monsters via Purge the Unclean]

[+30% attack speed when using Fury of the Faithful which will now gives you Burning Strikes] 

[25% crit chance and up to 55% total into beefier targets]

Difficulty: B+ (Doesn't ask much of the user to get value out of the kit)

[Straight forward gameplay; attack things until they die and be tanky while doing so]

[The melee weapon is simple but also has a pretty in-depth moveset that rewards precision strikes]

[The sidearm is versatile and functions as a both a picking tool and support for the main kit]

[We are sacrificing the ability to heal when we hit 1 health for extra DPS which takes away the base of Zealot's kit]

The last point can be used depending on what you want:

Purify Hatred to take Flamer as your ranged weapon

Blinded by Blood to commit to bleed synergy using the Bolt Pistol

Unrelenting Fury if you want to spam slightly more

Enduring Faith/Good Balance for a bit more Damage reduction
