The "Medic" - Wanna Crit?
 Hive Scum Build - Warhammer 40k: Darktide 

Only for Trauma Team Platinum members.

After Hotfix #83 - 1.10.2, the stimm supply now finally gives a stack of chemical dependency, as was likely intended from the start. This allows us to provide drugs to eeeeeeveryone while still taking a powerful stimm. 

This build is all about crits and spreading the drugs everywhere. After a successful dodge (+20) and with max chem dependency (+20) and shred stacks (+20), we're running at a cozy 80% crit chance (10 base + 5 from node + 5 from anarchist). You could add a +5% crit perk on the saw, for the memes. The Wildfire stimm makes great use of this with the extra finesse.

Post-hotfix, we can also take all the (mandatory) toughness talents (Precision Violence, Burst of Energy, Tis but a Scratch) while still routing through all the great toxin nodes AND now also picking pockets. Infinite ammo, great TDR and toughness recovery and insane boss damage. The constant dropping of stimm supplies and freely firing the needle gun on blue mode also makes short work of mixed hordes. It's not flame psyker levels of multi-target DPS, but it's more fun in my humble opinion.

Optional: 

• Swap Shred for Shock & Awe (somewhat diminishing returns at these levels of crit chance). Allows for better cleaving into mixed hordes. For even better cleave, add Wrath as well, but then we lose out on that sweet weakspot bonus from Refined Lethality.
• Swap to Ruffian (somewhat diminishing returns on crit chance).
