Skitarius Alpha Vanguard (v2.5)
 Skitarii Build - Warhammer 40k: Darktide 

Skitarius Alpha Primus Vanguard - The True Allrounder for Auric (and Mid-Havoc)

This build will constantly pump toughness to your team as long as they are in Coherency, but will certainly keep you firm as long as you don't get overconfident or don't get cornered badly. You position as a frontliner, being in the thick of the melee, but when shooters join, your shield is your autogun. The build's strong side is that it provides constant Toughness replenishment for the team especially when a bunch of ranged heretics start shooting. The talent pathing is somewhat peculiar but absolutely to the point. It maximizes melee damage with easily triggered nodes and keeps Toughness close to 100% in any possible situation. Key Talents are Resurgence aura, Power Overflow  and Restoration Protocol upon ability activasion. Your main weapon is your maul, regardless of the Ability. For your blitz you can either go with Artificer Servo-Skull and Medicae Servo-Skull (makes the most sense), or use Overcharged Arc Grenades . Servo skull kills may slightly enchance your Hybrid Combat Covenant , while the grenades are a somewhat underrated option that can save a run. Anyway, it's up to anyone's preference. About the Power Overload Keystone: this is absolutely the way top go for this build. Static Capacitor Drain 's passives are everything we need and with Critical Power Overload modifier we get a +15% bonus to Damage which applies to the enemies affected and thus is cumulative with other damage boosts. However if someone needs a tankier profile, he can swap CPO to Invigorating Overload for even better Toughness and some Stamina management. 

The build is 100% viable for any Auric runs and so far has been passing mid-level (25-29) Havoc missions.

Weapons

• Branx Mk III Arc Maul : Set perks are highly advised, those are the most common melee enemies you come face-to-face with on a regular basis and we need to make sure they can be killed quick. So are the blessings are fixed for this build. Confident Strike keeps your Toughness maxed out, so you can support your team with Power Overflow . Execution gives a big chunk of damage to Staggered enemies (which includes Electrified). When push come shove, you switch to your Arc Mode to delete Carapace platoons with the help of System Shock . While I use Arc Effeciency as my dump stat, there is very little fall-off in damage. 
• Graia Mk VII Vigilant Autogun : Now here's a real ace up your sleeve! Ghost with Advanced Combat Doctrines is a pairing that gives you a literal line of sight reach with 100% accuracy and ranged immunity. I wouldn't touch the perks here either. Critical hits are all we need for damage, and headhots are guaranteed with the Ability. The +25% boost to Unyielding enemies turns the otherwise weak VA into a decent monstrosity killer.

Curios: x3 Tougness

• x3 30% Toughness Regeneration Speed: Resurgence aura keeps your Coherency Regeneration going constantly. 
• x1 20% Damage Resistance (Bomber): Since Ghost keeps us safe from ranged weapons, we need only to worry about Bombers.
• x3 Combat Ability Regeneration: This is standard for any Skitarii build as far as I'm concerned. 
• x2 +12% Stamina Reneneration: A modest boost to help you manage your Stamina.
