The Arc Raider - Lightning Maul Support Build
 Skitarii Build - Warhammer 40k: Darktide 

Flensing Melee Refraction Build - "Knowledge is power. Guard it well."

Recruited into a fringe order of the Mechanicus, one most tech-priests only know by an old, half-forgotten name: the Brotherhood of Steel, bound to one doctrine above all others: find the STC.

The Arc Maul - Your Tool of Recovery and to brutalise any heretics in the way. Flensing Protocols goes hand in hand with this weapon due to its weight and slow swing speed, with the extra crit helping to proc Electro-Strike Conduit. In empowered mode, time it with Voltaic Emitter so the arcs spread cleanly across a group, for some wombo combo damage. 

Phosphor Blast Pistol - Your designated specialist response weapon, and the primary source of sustained boss damage through stacking Infernus. Not the centrepiece of the doctrine, but a respectable holdout weapon when needed. 

Voltaic Emitter - Not only a stun but also a damage dealer with Voltaic Arcs and a buff to your maul with Voltaic Motivator. Excellent setup against large groups, and it plays cleanly with any lightning buffs the rest of the squad is carrying. The Voltaic Arcs also play well with System Shock to stack brittleness into entire groups of crushers, turning them into an easy kill for your Maul and meaning Thunderous is overkill with the amount of carapace nowadays. 

Integrated Refraction Emitter - The Omnissiah's own grace, rendered cooldown-only by decree Sacred Fatsharks most recent revision. Reliable for revives, and for weathering pressure from gunners and Reapers alike. In melee, it earns its keep too, delivering three electrocution shocks across twelve seconds.  A baby Voltaic Emitter running its own cooldown and actively helping said cooldown thanks to Kinetic Repulsion!
