I think I heard that the AI has some kind of priority for artifacts, but I can't say for sure. The overflow bug should definitely be tested without the HD mod, on the classic version.
There's an interesting strategy involving Caitlin. You can let the AI recruit her, then send her to the tavern, where she'll learn all the control magic, fly back to us, and then we can kill her and dig her up.
The author also made all the angels and random monsters of level 7 on the Castle respawn bloodthirsty, so I could only beat the ice creatures on version 1.3.3. They are really mean :smile19:. I'm too lazy to play further for now.
