Commune with the parted

You bring back the soul of a the person or creature to the mortal plane (the target must be willingly choosing to return) once returned for the duration of the spell the soul is capable of possessing anything that has a living shape (EXP: a statue, a golem, or a corpse). While possessing the object the target is incapable of being harmed, and can communicate as if it was a living being. when the spell ends the soul is returned to the plane of which it was summoned and can not be summoned again for at least a year.

The returned soul is treated as a PC while summoned and can do what ever they were capable of while they were alive regardless of what they have possessed.
