havoc melee crit arc skitarii
 Skitarii Build - Warhammer 40k: Darktide 

still kinda working on the build but its in a place I really like currently. some of my choices probably super optimal but i liked for me. ammo deposit instead of foe render creed is bc im taking volatic motivator instead of uncapped arrestor. both servo-sinew surge and uncapped arrestor give melee attack speed, attack speed of different types stacks with less diminishing returns then attack speed of the same types. so the "melee attack speed" of servo-sinew surge and generic "attack speed" of voltaic motivator go together better than both sources of melee attack speed. i could run all 3 but the combat blade doesnt need THAT much attack speed. and thats also just way to much m1 spamming for my fingers. servo sinew surge over uncapped arrestor bc crit chance and crit chance is like the whole reason to run flensing over power overload. also voltaic motivator gives a potentially larger amount of attack speed and it benefits the arc rifle as well, which can tear shit up after ability use. the boost is for 15 seconds which is a huge time for a buff and this build does not need to wait for 3 charges every time to use ability so uptime can be very good. foe render creed cleave buff is tiny and does probably nothing for the combat blade, the 7.5% rending is good but its the same amount that 1 crit applies with system shock so i can pass on such a small buff. id probably take no aura at all but with 25 of the classes toughness baked into the aura, its really really hard not to take an aura. ammo aura rounds off my arc rifle so 197 reserve which is 200 in my mind and I like being at a simple number. 

I dont take any of the weakspot kill or weakspot damage talents because arc rifle does need weakspot hits and its inaccurate, better to aim for center of mass. plus a lot of combat blade kills are from flesh tearer bleed or electro strike conduit so no weakspot kill from those.
