Possession is an ability learned by the Rook Parlour.
With increased study of the soul, the mind, and the state of consciousness, a Rook can temporarily cast their awareness into that of their familiar when it is animating a corpse. This will allow the Rook full control over the corpse, though the Rook's own body will be left comatose and defenseless.
Take control of an animated minion. The sorcerer's body will be left comatose.
Usage: cast 330 [target], cast 330 while possessing to release the possessed host.
