I just tried this boss fight for the first time and something is definitely wrong, went in with full iron armor and forlon hope etsoc and shield and spent more time in the air than on the ground. Ate through 24 bandages in about 2 minutes and was able to land like 5 hits before dying from fall damage (extremely frustrating). I hope this gets adjusted in the future because I spent so much time preparing for this place just for it to be physically impossible. Ive tried 5 more times and while staying close to him and blocking helps reduce the slams, he will eventually do it and then he will continue to chain them until you die. I'd like to say that I like this mechanic as its a change of pace from fighting other mobs but I'm not kidding you when I say that this boss is impossible to defeat as of right now. I'm playing with mods so maybe that is the problem but this just feels wrong.
