Swap Technique

The Swap Technique was a spell involving the transfer of a person's soul and consciousness to another body or object. Only known by a handful of individuals, the technique allowed the user to directly possess different people or objects and potentially surpass the average human lifespan.

Mechanics
The Swap Technique allowed the user to transfer the soul of either themselves or a nearby individual to another human body or object. The desired soul resided in the targeted "body", sharing it with the occupying soul; the user could also move the occupying soul into another human body or object, such as the user's previously inhabited body, effectively swapping the bodies of the two individuals. It was also possible for the spellcaster to use the spell to draw a soul into their own body and soul. While sharing souls in the same body, the consciousness of one soul could be suppressed while the other uses the body.

An incomplete variant of the technique allowed the user to have their soul freely inhabit objects but only partially possess bodies. As a result, the targeted human body would have to have its consciousness suppressed to allow the user to freely utilize the body. In order to maintain the technique, the user needed to keep their true body near the targeted body they are possessing at all times. While possessing a human body, the swap technique caster could halt its aging while in use, allowing it to be used for long periods of time.

A complex spell, only a select few and powerful mages were capable of performing it, while a person would automatically be able to use the technique should they be resurrected via the Sin ark. In order to invoke the technique, the user was usually required to recite a short incantation. By using this technique, the user would be able to gain the targeted body's unique characteristics and abilities, save for traits ingrained in the soul such as immortality or HER Syndrome. As a downside, the targeted body's consciousness could resurge by triggering powerful emotions or memories, making it difficult for the user to control the body.
