I really didn't enjoy the fight mechanically on my initial playthrough, and even after fighting him at RL1 I still feel the same way. the spectacle is undeniable however.
Nice kill, I managed to beat this jerk RL1 using the same weapon. Though I also used vow of the indomitable to avoid some of his crazy attacks that I was not too confident in dodging. I also sacrificed half my red flasks for blue flasks so I could consistently use dragonwound slash and vow of the indomitable when i needed to.
Very nice, I always forget Vow of Indomitable exist lol, hence why I used Raptor of the mist instead. They basically do the same thing anyway, so it is what it is :)
