I had both morrigan and wynn in my party. Blizzard could be cast on the front enemy at max range without the enemies noticing, and hitting the front guy would of course pull the entire room, and they'd all freeze solid. Then I'd cast lightning storm (or whatever it was called), and everything in the room would die without taking more than a few steps. If there were yellow enemies, sometimes they wouldn't quite die, so I'd throw a stone fist or crushing prison at them. Shattered. You could kill an entire party-wiping room with about 25% mana, taking no damage.

Ooooooooverpowered are the mages.
