Juvie Hive Scum
 Hive Scum Build - Warhammer 40k: Darktide 

Basic Atrox Mk IV Tactical Axe / Atrox Mk VII Tactical Axe leveling build with increased survivability, but well usable into Auric.

A more forgiving beginner introduction to the fragile Hive Scum play-style than most, especially if you can craft a good Tac Axe if you have the materials and mastery from another character so you only need to level up the Branx MKII Needle Pistol Needle Pistol.

Coated Weaponry & Blackout toxins grant Toxic Renewal toughness regeneration , Toxin Mania damage boost and Targeted Toxin enemy de-buff.

Use the Branx MKII Needle Pistol to soften up heavies and target snipers, or poison small groups with alternate SA fire mode before going in.

Use the regenerating Blackout charges to stun and poison larger groups and open up Bulwark shields.

Use Equip Cartel Special as boost, because of treacherous Rampage!'s de-buff at the end. You can still use it as last ditch toughness regeneration. DPS will still be very much OK. You could swap out the attack speed line for better toughness or cool-down, or a bit of both.

Don't overlook the Atrox Mk IV Tactical Axe special attack since it can pretty much one- or two-shot most lesser armored specials.

For curios, you could start out with stamina, toughness, wound, and move to full stamina for more DPS later. Afterwards you can start leveling shivs with basically the same build..
