Melee Clanker build (High-Havoc)
 Skitarii Build - Warhammer 40k: Darktide 

Info about the build: 

This build Shreds everything in melee and quickly takes out specialists at range. It also destroys bosses extremely quickly.

The build leans heavily into Personal Power over team utility, with the exception of some talents like the Medicae Servo-Skull , Artificer Servo-Skull (+15% dmg taken debuff on target it hits) and your Branx Mk XI Phosphor Blast Pistol (which puts 15% brittleness debuff on target/s it hits.)

Have played this a bunch in havoc 30-40 now, and feels pretty great and optimized like it is now. You can use this build as just a Template though and modify it as you personally see fit, a lot of small changes can be made depending on your preferences.

If you are wondering about Threat Detection Imperative  and Superior Defence Engrams these talents can be procced by your Artificer Servo-Skull so they have pretty good uptime. You can flex these talent for anything else you prefer if you are willing to give up survivability. You can also flex Enhanced Capacitance Protocols , but it is nice to have this imo. (In Havoc, for Auric you probably don't get too much out of Enhanced Capacitance Protocols )

The +2 Stamina on the Branx Mk XI Paired Transonic Blades can be swapped for Unyielding or Flak if you want.

But keep in mind that none of your weapon blessings and damage perks affect Chordclaw Strike  Which is your main source of Unyielding damage anyways. I prefer having +2 stamina on the melee weapon instead of having a +3 stamina curio personally. 

(You can swap out the Branx Mk XI Phosphor Blast Pistol for any other Ranged weapon you want to use)
