An Imprisonment Curse was a spell that would call upon the deity Corseth to trap the soul of the target with an object, also obliterating the target's body in a painful process. The victim would remain trapped within the object, fully aware and capable of perceiving the world around him/her.
The spell manifested as small burst of energy that would swirl around the caster's body, and then coalesce into a single mass of energy that would blast against the target. The energy blast could be deflected by a mirror. If the caster was caught by the energy, he/she would suffer the curse's effects.
The witch Catherine Madison performed this curse and tried to use it against Buffy Summers. However, the Slayer deflected the spell with a mirror, which caused Catherine to be caught by her own curse. As a result, Catherine's sould was trapped within her cheerleading trophy.
