Our party returns to Castle Overkill with the Zombie's Bane Talisman - only to learn that we need a spell Arwen hasn't learned yet to leave the maze guarding access to the castle treasure room (and we can't just duck out, learn the spell, and reenter the maze, either :( ). Fortunately, we did save before entering the castle, so we recover from that saved game, learn that the Khost Mage's Guild bans anyone who's been hanging out with Radamanthis the Rogue Teacher, and later find that the Knor Mage's Guild can teach the spell we need to Arwen - except that she can't afford it yet. Looks like we'll have to go adventuring elsewhere to find enough loot to finance our mage's education -- so we can finally complete Castle Overkill!
