Beltfed Buckshot (With Dog)
 Arbites Build - Warhammer 40k: Darktide 

With the update to Blessed Armament in Beyond the Hive, Castigator's Stance, once capable of giving the Arbites access to a quad barrel shotgun, is now capable of delivering the will of the Lex Imperialis in as much buckshot as you can carry without reloading. With the cooldown rate on this build you're pretty free to pop CS whenever you have it, but if you hear a horde coming you might want to save it for the fun part of this build. The shock maul is fantastic on single target using overhead swings, and great for crowd clear with the horizontal heavy light combo. If you ever need a cardinal direction's worth of chaff enemies to stop existing (especially effective in chokepoints), just pull out your old reliable beltfed shotgun and erase mixed hordes from memory. So long as you keep getting kills once every other shot nothing but death can stop you with CS active, and having 15 in the chamber to start with means you get a lot of "freebies," either missed or non-kill shots, before having to reload like a neanderthal. Slugs are fantastic for picking off specials from afar or staggering pesky bulwarks who would try to interrupt your rain of lead. With this dog version, you trade some boss damage and shock mines for the imperium of man's best friend.
