Blood for the Blood Dog - Turbo Pupper
 Arbites Build - Warhammer 40k: Darktide 

The Arbitrator Penances want you to blast 3500 Elites and Specials marked with Execution Order pupper vision and what better way to do that than with a super dog that bleeds, brittles, shocks, and rocks their faces off? Zarona Mk VI Combat Shotgun buffs are noticeable on the cleave side - you can get 2 Poxwalker per shell aiming or from the hip, and the special now cleaves like a Zarona Mk IIa Quickdraw Stub Revolver and can blast 5 pox walkers at once! No Man-Stopper blessing needed any more - you can slam out miniature power swords and bleed stacks with the special for crowds and use the buck shot for specials and elites. Combat axes bonk carapace good and so if there's a big chunk of Dreg Gunner in front of you just slam that Break the Line active and start swinging, alternating push attacks and Heavy attacks to swing right to left to right again. Combat shotguns do great vs Monstrosities already and with the dog vision buffs from Keeping Protocol you can burst down a Beast of Nurgle real good with the buck shot.
