Possession is the ability to take control of another, usually by entering their vessel. Using this, you are able to command the movements, or even take hostage of, their body, in essence becoming a new individual. It is usually done by the likes of souls and ghosts, granting them a physical body, however there are those amount the living who can claim this to their arsenal. It can either be intended to be permanent, and therefore only cancelled out by defeat or bordem, or temporary, to quickly hijack the abilities of another.
