One of my players is going to be playing an Imp. I was wondering, what happens when an Imp dies? In old additions, they reformed on their home plane and returned 100 years later, but I know that 3.5 changed that. So, if an Imp PC died, would he be gone for good? Or only for 100 years? And if he does reform, but is banned from the Material Plane, how can the rest of the party get him to come back?
