Thanks for the welcome, and DOH, gotta watch the floor, I thought I had missed something as well, managed to kill the dragon without too many problems, but I thought that something may have been in the Demi-Lich's lair, couldn't kill him so there had to be something else.

I didn't find the maze all that confusing actually, the demons in a few rooms were fairly tough. I'm glad I had an undead hunter, I hate level drain.
