*SPOILERS*


Kary/Malirith was never too tough for me because I always did Ice Cave, Castle of Ordeals and the class change before going to the Volcano. Once I beat all Fiends before fighting Kary/Malirith, and I finally killed her on level 46. I think Lich is the hardest of them in Origins. He's got a lot of powerful spells, and Nuke/Flare really hurts you in the rematch in ToF past. In NES, the 2nd encounter with Kraken was the hardest. He hits for hundreds of damage, which can instantly kill a mage character.
