My highscore is completely fucked up by playing around with high lvl savefiles (I save interesting high lvl chars before final descent). But my highest real score is:
Code:14 347 915 Versace (tim). L50 gray elven wizard (F). 42 430 290 xps. 152428 turns. Ascended on 5/20/2008 (two days after my birthday, guess what I was doing on my birthday). She transformed into an avatar of Order in the palace of Andor Drakon.
