So I've been playing Class of Heroes the past week and beat one of the hardest bosses yet. She had extreme speed and evasion. It took a couple rounds of casting Accuracy buffs and slow on her before I could hit her. Not to mention she had a move that turned you into ash. That bypasses Instant Dead straight into Instant More Deader. And that's made worse cause my OCD makes me keep my team with the same XP so I had to reset every time she connected with it.

So anyway, what are some of your favorite pain in the ass storyline bosses from any game?
