 Skitarii Build - Warhammer 40k: Darktide 

Like a slower version of Weapons Specialist . In between purgator servo skull and arc grenade. Arc grenade provides stronger defense against massive density spikes of armored elites. However, having the servo skull increases the uptime of a ton of your perks such as Progressive Plating Matrix , Threat Detection Imperative , Superior Defence Engrams , and Hybrid Combat Covenant . So just having that little laser skull makes your base kit much stronger and resistant. Plus, even though the Purgator Servo-Skull does less damage to elites, especially as a burst, your arc maul is the perfect complement to bolster that by keeping dense hordes in the fire for longer/safer with empowered pushes. In addition, the node required to get to the Arc grenade, Weakness Analysis Doctrine , which although is good on other builds, it doesn't have good uptime in this build.

Overall, with the laser and purgator skull, you sacrifice the ability to quickly counter-burst against massive enemy spikes, but you get an overall much better kit.

With purgator servo skull, you get 5 charges so use them liberally. You can swap the Medicae Servo-Skull for Restoration Protocol for more toughness during ACD, but I find that if you put a flame skull down, you need to worry about melee chip damage way less anyways.
