The Ice boss was just as egregious and suffers from the same problems. He constantly slams the floor and uses aoe that takes the player out of the fight. While fighting up close you have to weave harden in every combo so he can't get off that annoying super fast swing that's unreactable to most players. He also disables the lock-on camera constantly and spends most of the fight sliding away from the player in his second form rather than attacking them

Oh yeah, I forgot that sliding bit. That was annoying too. But that was acceptable level of annoying for me.

The final boss just felt like a painful chore and the game was literally trying to kill me with its epilepsy inducing graphical glitch
