More specifically, can you make an honest-to-god-has-all-the-mental-stats artificial intelligence?
I'm aware of Haunt Shift, but I don't have whatever book it's in, so no luck there.
Maybe something to do with Schism? Is there any way I could dump that split-off mind at a wizard's tower, let's say, go off and adventure, and come back and learn spells from the split mind?
This is more a question of interest, not something I would use in a game, unless it was IC/useful/simple to do (pick 2)
