@golguin: I'm at 108 on NG++, just got to the first boss (no name just in case that would be a spoiler). Right now I'm being really stubborn and just sticking to untransformed Saw Cleaver R1 attacks. Dying a lot but slowly figuring him out and getting that rhythm down bit by bit. That mid-range lunging attack he does always seems to come when I'm about to make a decision and I feel like I'm moving in quicksand for that split second.
After I handle this business I'll go back and step to the chump with the beast claws ... he ain't shit
I finally beat that first boss with my level 99 character on NG+ and it was a very satisfying fight. After 10+ deaths I was finally was able to consistently dodge most attacks that resulted in a very clean kill for me. I like bosses that die relatively easily after you finally understand the moveset.
I'm currently working on a 2nd boss, which I expect might be a secret optional boss due to the hoops I went through to get the ability to fight it.
