"You touch a dead humanoid or a piece of a dead humanoid. Provided that the creature has been dead no longer than 10 days, the spell forms a new adult body for it and then calls the soul to enter that body. If the target's soul isn't free or willing to do so, the spell fails."
I think Karlach, Gale and Tadpoles is why this spell isn't in the game... It would instantly solve all problems.
