I was using the SMG class mod that gives +5 Forbearance to take out Bloodwing, but I found another similar mod that gave me +6 to the skill Duty Calls.
I had completely given up on this skill in UVHM (though I abused it heavily in TVHM and NVHM), but getting that mod made me want to give it another go…
Well I found something amazing! It works AMAZINGLY with the Lascaux SMG! (a Light Lascaux I was using). The +33% smg accuracy boost DOES work with Lascaux I can confirm, it brings the bullets closer together give the gun better range! But it was doing awesome damage at short and mid range. A non-elem Emperor (still haven’t found one) or Fox SMG in other slot to snipe with makes the build very viable in UVHM. I like to use Vladdoff fire grenades also to do fire damage that my guns are lacking in.
I managed to get some video of footage of me using this design, hopefully I can upload it here soon.
