Electroknight
 Skitarii Build - Warhammer 40k: Darktide 

A tanky all-rounder build focused on Elecrocution and the fantastic crowd control and damage of the Branx Mk III Arc Maul.

With all capacitance generators (including 5% each specialist/elite kill) we have Voltaic Emitter ready quite often for anytime that our Maul's Hammerblow blessing isn't already staggering the digital Hel out of the enemies. All of our electrocution effects apply brittleness and improve our toughness regeneration (which is also regenerating due to our aura Resurgence ), resulting in a build whose toughness gains are among the best in the game.

The build focuses on engaging Elites/Specialists since that's how we maintain Flensing Protocols stacks (feel free to pick up Enhanced Capacitance Protocols  if you find yourself struggling to keep up max stacks), which provides a huge damage and survivability increase (which sort of goes without saying: all of Skitarius' keystones provide damage and mitigation!).  It also provides attack speed and crit, though the crits aren't particularly great for Arc Maul (it has a below average crit multiplier (+60%; an "average" crit multiplier is about +100%), and while Arcs themselves can crit, the multiplier for them (+30%) is even more miserable!).

Single Target Combo: Heavy > Heavy > Light > Heavy (repeating Light > Heavy)

AOE Combo: Light > Heavy (repeating Light > Heavy)

Arcs chain between previously-electrified targets! So use your ability or other sources of electrification to try to electrify at least 4 targets around you before you activate your Maul's special mode (and do use it, quite often, it's very strong!) 

Use LasPistol for mobility. It switches almost instantly, so even in very short moments you can sneak a little extra sprint speed! It's also for specialist eliminates, as well as for landing reliable, solid ranged damage against Monstrosities (aim for all weakspots if possible to maximize crits to maximize Infernus stacks).
