I think I broke the tomb of Dahris-Bok. I sent my PC in and she made past the chasm, the triple portcullis puzzle and fought a vampire. She defeated the vampire then died of her injuries. So now, my party is at the starting portal, but the very first portcullis to the main room is closed. Is there any way of resetting the dungeon (preferably without losing my dead PC's stuff)? I think I might be screwed on this.
