Astral Embodiment

Astral Embodiment (実施星, Hoshi Jisshi) is a special Magic which compliments Celestial Spirit Magic by allowing the caster to take on the traits of certain Spirits in combat. While the caster receives the magical energy signature of the Spirit, the two creatures do not fuse, but the Spirit is instead sent back to the Spirit World and the caster will take their place. This allows the caster to summon more Spirits while maintaining the abilities of the other Spirit. Due to the fact that it is limited to Celestial Spirit Mages, like the spell Urano Metria, there are rather few users of this Magic. To compensate, just about any Celestial Spirit Mage can learn how to use it.
