Arbites Generalist High Havoc
 Arbites Build - Warhammer 40k: Darktide 

Concussive talent + Skullcrusher blessing permits all targets to take 40% more damage on weakspot hit, even bosses. Using the special on the Indignatus Crusher applies the stagger + Skullcrusher debuff an all enemies in an AoE around the initial target. This means we need to hit heads a lot, and occasionally open our combos with a special attack.

Practice with the Indignatus Crusher. The weapon has insane damage output, but you need to learn the effective combos, learn how to attack enemy heads with the push-attack uppercut, and how to switch between horde-clear and single-target very fluidly. Don't overuse the special attack -- it's for debuffing and openning up Bulwark shields. Spamming it will cut into your damage.

The dog is for staggering groups of armor and stagger bosses. If a boss is staggered via the dogsplosion, AND you've got 8 stacks of Skullcrusher on them (+80% damage taken from all sources), then congratz, you've contributed more damage to your team than anything else in the current meta.

Our Execution Mk III is for trash clear at range and stunning specials. The special shells can be used to sweep through groups of elite gunners. If you don't like it, consider using the Shotpistol for better single-target damage or the Bolt Pistol for an all-rounder weapon.

We have a ton of toughness regeneration nodes. Force of Will and Walk It Off ensure between 15% and 25% toughness regen per second, minimum, for nearly the entire match. When overwhelmed, use Castigator's stance. If you're on fire, use Castigator's Stance. If you're about to be sniped, use Castigator's Stance.

As a matter of fact, just constantly use Castigator's Stance. Don't think. Stance.
