A Guide for Brute Force Heavy Eviscerator mk XV zealot
Build for Darktide

An updated version of the guide https://steamcommunity.com/sharedfiles/filedetails/?id=3122499591
Hello Celestine here,

This is my battle scarred build for heavy eviscerator mk XV. This build is meant for any difficulty level and is a complete jack of all trades, though it requires a bit of melee experience as it revolves around staying in melee combat for the vast majority of the time.

Eviscerator:
Perks:
Having 1-2 wounds + 25% maniac allows you to 1shot mutants with a single heavy, no need for revving and it helps to deal with ragers, +flak helps with just about all the other armored threats which there are going to be many of. Flak jacket ragers or maulers (hit their body for flak damage as their helmet is carapace).

other perks:
+carapace can be totally legit to rev through maulers heads/crushers

+unyielding could be legit I think, it could help a lot with killing monsters but im not sure if it's needed

+crit chance totally legit to help you with resetting fury of the faithful

Blessings:
I'd say they are non negotiable. Rampage is a ridiculous damage amplification, it is very easy to activate and to keep up.

Shred is the meat of this build and it is the no.1 thing that allows this build to work without Blazing Piety. When you stack it up to full you can crit very often, it is pretty much Blazing Piety  keystone itself as long as you hit enemies! SHRED RESETS TO 0 if you whiff an attack. The lower your hp the faster you attack and more damage you deal. The attack speed allows you to trigger crits very often + Fury of The Faithful attack speed steroid is handy. Stay close to enemies and dont ever stop swinging until everything is dead. Keep dodging and sliding, press Fury of The Faithful to gap close or restore toughness.

Revolver

Perks:
Anything goes but I think +crit chance helps a lot I use revolver mainly to kill high value targets such as trappers/snipers and anything I can't reach quickly enough so could be bombers, flamers or gunners you name it. Aim for the head and watch everything fall apart. Also revolver penetrates enemies so you can shoot a trapper behind trash if you aim true. 
Blessings:
I think armor rending is very helpful, surgical is a decent choice but doesn't fit my play style at all. My current revolver is armed with point blank so I get higher crit chance after melee, honestly feels pretty neat. Roulette could be good too, didn't try tho.

Revolver is a key part of this build. Heavy Eviscerator mk XV is not just slow in actual melee combat but also in it's movement speed. Every time you are outside of active melee combat, practice switching to your revolver to run faster and have noticibly larger dodge distance. Do remember that you gain more dodging distance when you dodge slide off of elevation, even a small box will do the trick.

Curious:
Wounds are a must to enable the build and martyrdom. I love stamina regen for obvious reasons remaining bonuses can be anything ranging from +gunners +hp +toughness +toughness regen, whatever fits your playstyle the most.

Remember to not be afraid of staying low on hp (3-4 wounds is good to go you gain a ton of stats) with enduring faith and 1 wound you have like 110% toughness damage reduction. Until Death + Holy Revenant is one of the most powerful combos in the game, don't ever forget it! You should stay close to melee action and be your team's frontliner for as long as you have that combo up and running. Look out for trappers, snipers, poxbursters and hounds. These enemies can very easily shut you down or take a chunk of your health bar. Other than that you can tank insane amounts of damage when you actually kill stuff and regain toughness. The larger the horde, the more resets for Fury of The Faithful.

Knives may seem like an unnecessary tool but trust me, sometimes even with light fast reactions it's difficult to switch to your gun to shoot the trapper or snipers. You can always throw your trusty knives to deal with these issues and remember you basically have an infinite supply of knives so long as you kill specials/elites which is really easy with evisor.

Fire/stun grenades may be tempting but with this build YOU ARE the fire grenade. Usually fire grenades are a great subsidiary for builds with little to no aoe damage, you can just throw them on the ground and clean up the mess. With this build you become the unstoppable force able to rip through just about anything they throw at you with enough practice. And in addition to that, grenades block you from getting one of the best talents in the game which is Thy Wrath be Swift.

Thy Wrath be Swift is easily one of the most powerful talents in the game. You are no longer stunned by enemy melee attacks but also bomber grenades explosions, shotguns and reapers no longer push you away with their guns. This ability to literally ignore most stuns in the game allows you to walk through hordes and ranged enemies alike. Every time you lose your health you gain movement speed bonus which can help you reposition around the map. Therefore, you can even fall off of small ledges to lose like 5 hp and you gain a nice speed boost for a short time. 

The brute force name is not accidental. With this build you are quite literally able to brute force your way through just about any horde that doesn't have crushers, bulwarks or bosses in it.

Against ragers push into them when you have Fury of The Faithful as the ability will stagger them all. Then keep swinging your lights and thanks to Shred you should gain enough resets back quickly to crush them.

Maulers are stunned by simply swinging lights into their body, handy no? 

If there is only 1 or 2 ragers/maulers rev your weapon and swing a heavy, it will kill them much faster but in larger groups lights should be a lot more efficient.
With high enough stats or just simply missing a wound or two you can rev evisor, press Fury of The Faithful  and swing heavy into the head of a crusher to 1 shot him, other than that you should typically need 2 revved heavies to kill crushers.

Keep preachin and I will keep updating the build
