There's a slight problem with some of the arena challenges. There are cases where you will be stuck in a "loop" where you can't do anything. I.E. being stuck on berserk and numb, yet absorbing any damage that's being dealt to you. I know that these challenges are supposed to be hard, but when something like that happens, it's just frustrating.
@pyrotechchild Well, maybe you shouldn't have used the glitch to get your level 50 to begin with. Play through the game again, but this time, do it fair and square.
