One that's fresh in my mind is the Magic Master at the top of the Cultist Tower in FFVI. I mean, he wasn't actually too tough but when he dies he casts Ultima which at that point... wipes out my entire team. The worst thing is, there is no save point anywhere on the Cultist Tower which means I have to climb the whole thing again... which includes fighting one of the eight dragons. What a bastard.
I mean, I could've avoided death by casting re-raise on one of my team but how the hell am I supposed to know that? If you're gonna pull a dirty trick like that at least let me save before the fight
