1-4 Bleed Stacks on non-Weak Spot Hits.
70-100% Rending on Backstab Hit.
3-6 Bleed Stacks on Critical Hit.
6-12% Critical Chance for each Enemy Hit by your previous attack. Stacks 5 times.
Gotta say this is such a clutch build because it one shots everything but bosses.
It one shots crushers even without duelist active
I prefer lacerate because it's easier to get your bleeds out on EVERYTHING and keeps your crit chance higher than Flesh terror imo. which gives your more CD reduction to go stealth faster
I left the curio 3rd slot open because I use Ordo dockets on the 3rd option but if you want more CD reduction go for it. I already have pretty quick CD from the crit and backstab kills that I didn't even know I had ordo dockets on still. (and I won't be changing it cause definitely don't need it)
The shotgun is also good to stop raggers with normal fire and to just reck anything in a line with Alt fire
It 2 shots snipers (2 alt fires kills them from any distant)
It also helps to push a group of gunners with a normal shot and you just run up on them while they are staggered for knife pokey pokey
Knife throwing is pretty nice too cause if you see a netter or anything you just tap them on the head and they or swap to shotgun normal shot and run toward them to stab stab or just keep shooting them if they didn't die from the first shot.
