Would it grow into the body of the creature that I currently possess, at the time of casting clone, or would it grow into a copy of my original body?
If I return to my original body (after Magic Jar ends), then at some point die after the clone has matured, will I be able to enter the cloned body of a different creature (that I possessed at the time of casting), even though it does not match the original body?
Clone: This spell grows an inert duplicate of a living, Medium creature as a safeguard against death. This clone forms inside a sealed vessel and grows to full size and maturity after 120 days; you can also choose to have the clone be a younger version of the same creature. It remains inert and endures indefinitely, as long as its vessel remains undisturbed. At any time after the clone matures, if the original creature dies, its soul transfers to the clone, provided that the soul is free and willing to return. The clone is physically identical to the original and has the same personality, memories, and abilities, but none of the original's equipment. The original creature's physical remains, if they still exist, become inert and can't thereafter be restored to life, since the creature's soul is elsewhere.
