Gungryn don't have to be wimps Slab + Ripper 5 Glugger | Auric Ready | UPDATED 05/11
 Ogryn Build - Warhammer 40k: Darktide 

UPDATE 05/11 CHANGES:

1.  Swapped out Unarmored% on Slab Shield to Carapace% because Heavy Hitter allowed us to reach breakpoints regardless.
2. Swapped out Health% Curio for Toughness% after further testing.
    

Versitility. Survivability. Special Killing. Boss DPS. All in one package.

This has been my favorite build for pretty much forever. The build makes use of Slab Shields Heavy 1 -> Block Cancel "combo" to horde-clear and delete close ranged elites, while making use of Ripper 5's hipfire's secret trait, which has incredibly high minimum pellet count letting you crossmap Trappers and Snipers with it. 

Mk5 Ripper applies two stacks of Light 'em up per shot while braced, letting you easily kill every boss on Auric Damnation with two magazines under the effects of Point Blank Barrage. This means not just is this build extremely versatile, it also matches your typical Achylys PBB build in boss DPS.
 

Big Friendly Rock

The main purpose of Big Friendly Rock is to delete Mutants and grant us access to the Slam talent. Slam gives our Slab Shield more consistency in triggering Oppertunist and is overall more impactful than Soften Them Up. You can opt. into taking Frag Bomb if it's your preference, but you'd be losing out on your ability to easily delete Mutants whenever they're in your view.

Coward Culling

Not exceptional, but still useful when mag dumping elites and shooters. Mostly taken due to point constraints.

Point-Blank Barrage

Fantastic ability that gives this build the capacity to easily delete bosses and hordes of elites that Auric likes to throw at you often. With the Mk5 Ripper you're able to dump two braced magazines while in PBB which is more than enough for any elite pack and enough for any boss.

Talent Choices

I'll run by the justification for various talents in this section.

• Lynchpin + Towering Presence: Ogryn has pretty insane coherency regeneration, and larger aura radius helps us get Survivalist aura from our Vet, unless they're a worthless Fire Team user. :^)
• Heavy Hitter: Necessary to make Slab Shield work without Bonebreaker's Aura. Even one stack of Heavy Hitter will let Slab Shields Heavy 1 horde-clear just about everything. I know it might seem like a large point investment but without it the Shield loses it's effectiveness.
• Bruiser: Point-Blank Barrage has a VERY long cooldown. It shouldn't be surprising we'd want to reduce that.

Foe-Rend Mk V Ripper Gun

I'll run by the justification for the weapon build in this section.

• Maniac %: Required to 1 burst Trappers with the hipfire.
• Unyielding %: We kill every other Elite/Special quickly besides Reapers, this helps. Also ups our boss DPS substantially.
• Blaze Away: Fantastic damage boosting blessing. Keep this on and let 'er rip!
• Fire Frenzy: Can be substituted for Cavalade, helps significantly when wiping crowds of elites.

Orox Mk II Battle Maul & Mk III Slab Shield

I'll run by the justification for the weapon build in this section.

• Flak %: Required to delete helmeted Scabs.
• Unarmored %: Required to delete flak-armored Scabs (unarmored heads).
• Brutal Momentum: Enables us to kill 5+ enemies per application of Heavy 1.
• Oppertunist: Can be substituted for Skullcrusher. Helps us kill Maulers and Crushers faster, which the shield usually struggles with.

Curios

I'll run by the justification for the curios in this section.

• 3 Toughness: We're operating at +51% Toughness. I find this more than usable on Auric Damnation.
• Combat Ability Regeneration: Knocks off about 9.6 seconds from our Point-Blank Barrage. You can suppliment it with Toughness %.
• Toughness Regeneration Speed: Quintessential perk for Ogryns. Combined with Lynchpin Darktide starts feeling like Call of Duty.
• Damage Resistance (Gunners): In my personal opinion a must have on every single build. Gunners are unavoidable, omnipresent and without DR curious melt you instantly.
