I have the 1.34 patch loaded. The problem is that I can't even touch him. He just stands there and does nothing and no melee or magic attack has any affect.

I can go back to before I found the the Demon and try again, but I wanted to make sure that I was doing the right things first. Other than the dungeon whre the Demon is is there any other caves, dungeons, tunnels, etc in the wastelands? I didn't find any. Just trying to see if I missed something.
