Well, I beat him. Finally. Had to do it twice cos I lost Anomen's stuff, but I did it. On ToB now, finally. I love it, really great. Thanks for all the help! I really, REALLY appreciate it. Oh, and for the record, Jaheira's scimitar was Scimitar +3, Water's Edge.
And Imoen was a lvl 14 mage...argh, woops...nm, I beat him!
