Reincarnation Ritual

Transmigration Magic is a type of magic used to transmute the soul of an entity from one form of being to another. Commonly conducted via a third party, the transmigration arts allow one's soul to be into a new physical body.

Mechanics
Transmigration magic's primary purpose is to supply a being with a new body, and was often used on formless entities such as spirits or disembodied souls. Mages are required to prepare an astronomical ritual in order to perform the technique on another party. The procedure for the ritual involves drawing a symbol on the ground and having the target imagine the desired appearance for their incarnation. The ritual can be used seemingly limitlessly, making it possible for targets to return to their original forms.

After the transmigration, targets of the spell have all the capabilities and limitations of their chosen form, and may experience a disconnect between the abilities of one form to the next. Despite this, they maintain all their core, spiritual abilities, such as immortality or their inherent magical power. While powerful, the ritual spell requires the affected target's cooperation to be properly cast, making it useless against opponents in combat. However, when utilized by the god Held, the technique is not subject to this limitation and can be cast at any time, though could only be used on his forest spirits while they were in his forest.
