SpikyGOG: 150-200 per swing is just not possible, I guess you meant per round?
Maybe not consistently, but I did see those numbers popping up per swing. But that was the one lucky playthrough where I got the Excalibur. ;)
SacredPath: Actually, you can cast an infinite amount of them per combat due to magic nectar and mana stones. That takes quite a bit of micromanagement though.
Yeah, but that requires one character spending a full turn to use them, whereas fighters rarely have to worry about stuff like that. Anyway, I don't advocate a melee only party. That would be a very difficult playthrough, especially against ranged creatures or stronger melee opponents. Balance is key in this game.
