The Instant Death spell (Which I didn't know at the time) won't kill him, being that he's already dead, but it will do some damage. Imhotep will respond to it like a guy who got hit by an arrow in the leg. It will hurt like hell but is only lethal if hit multiple times with it. Yeah, the whole "Instant Death" vs "Cannot Die" thing is a bit of a problem so I made it more of a damaging kind of thing.
