well i beat this game back in 1981 when it was on apple. i remember that i killed wernda without having learned malor/tiltowait yet. so i was stuck after killing werdna and i didn't know how to get out of the maze.two decades have passed, and i've mastered almost all versions of wizardry (apple, pc, nes, snes, gbc.) i've no better thing to do other than creating immortal characters by hex editting. 
you know, in nes wizardry they've taken the fun out by only allowing werdna be killed once. so i have to discard the amulet everytime after i killed werdna.
