Is there any better way to build ogryn noife?
>Mk IV
The one with light attacks that go stab stab horizontal, and the horizontal heavy for horde clear.
>dump stat
Mobility is the main reason I'm even using the thing, and I am NOT dumping it. You get a pretty significant speed boost going from 60 to 80.
I'm trying to think whether other dump stats might be useful. I ended up settling on dumping cleave because I'm already spamming the single target attacks everywhere it actually matters (crusher spam that can't be cleaved through). The (swap or push attack into) heavy -> light cleave combo seems to be performing adequately against trash anyway. I haven't found a need for Heavy Hitter's cleave either, but I've only tested the build in armorspam events and maelstroms. I'm not confident enough in my knife skills to bring it into havoc yet anyway.
>Tenderizer
Guaranteed +25% strength is pretty fucking good when Slaughterer is inacessible while fighting bosses. I've also found myself using the punch relatively often just for safety, since the knife's stagger is otherwise kinda bad.
>Confident Strike
The attack speed on this thing is fucking ridiculous, so it provides pretty crazy amounts of safety.
>Slaughterer
I'm still debating whether Slaughterer might be better over Confident Strike. More strength is obviously fucking insane, but so is 8% toughness per hit on a weapon that attacks like 3 times or more per second.

I've been running the knife with Bull Rush, Indomitable and the full 15% rending to absolutely dismantle armor. I've been pretty pleasantly surprised by how quickly I managed to fuck up monstrosities with it. It's not quite Branx pick, but it doesn't need to be.
