Just one question, now there is a bug in my game. One of the elavators that leads to the truth arena on the dwarf land has been stucked by a evil beholder. It's just on one side of the elevator and I can neither attack it nor make the elevaor moving. Can anyone tells me if I can correct this bug? If I can't, can anyone tells me what you get for completing the truth arena quest? 'cause I really want to know what I'm missing here. Thanks a lot
