The Tertium Typewriter (Autopistol Streetsweeper/Support Build)
 Skitarii Build - Warhammer 40k: Darktide 

This build is focused on Advanced Combat Doctrines uptime to essentially negate the downsides of the Ius Mk IV Shredder Autopistol by locking onto every possible Weakspot within view of your crosshair, making use of the given mobility from Superior Tracking Litanies and the gun's innate movement to run around ADS when not making use of Advanced Combat Doctrines to turn all Disablers and Specials into a paste.

Medicae Servo-Skull is your friend and is your main tool to keep your allies up while you turn everything hurting them into paste, Purgator Servo-Skull is unoptimal I hear but being able to soften up a hoard for your allies WILL save runs. Always be sure to Double-Ping heavily armored specials like Crushers so your Artificer Servo-Skull applies Brittleness!

Use your Branx Mk XI Paired Transonic Blades (or other preferred melee armament) to fish for crits to refresh Advanced Combat Doctrines, and importantly hoardclear to build Capacitance! Melee will be your main way of dealing wirh Crushers, since your Ius Mk IV Shredder Autopistol is suited for killing literally everything else.

Redline Capacitors stacks upkeep is good to keep in mind (you'll need to use a whole bar of Advanced Combat Doctrines to gain one outside refreshing charge via Capacitance) though the Advanced Power Management and Moebian Conductor are your tickets to playing the Harmonics of the Machine God for all to hear - the distinct rat-a-tat of your pistol killing enemies due to signifigant damage buffs. 

Restoration Protocol, Surge-Extension, Servo-Core Recharge Engine, Superior Defence Engrams, and Threat Detection Imperative all serve to bolster your toughness, as long as you are sending bullets down range you should have toughness.

Your Trinkets all need to have Combat Ability Restoration on them!!! More Capacitance = More Advanced Combat Doctrines = More toughness & more enemies off the board!
