Warhammer Fantasy

A complex and powerful spell that takes many components to complete. Including a preparation of a trapping vessel for a week and 1,000 gold, and additional resources. The caster places a person in a ritual circle and draws their soul into a trapping vessel. The body continues to live, but it is hollowed out of personality, and is almost catatonic and the body needs to be fed and supplied with drink to survive, it also ages as normal. Any possession spells cast on the body don't require saves anymore. The condition is permanent until the soul is released within 100 feet of the body. If it is released away from it, or the body is dead the soul gets lost and becomes a tormented ghost. The spirit in the vial can be forced to possess another body, through another ritual, though the body needs to be hollowed or brought from the dead. This is a fowl spell that is considered necromancy most abhorrent, it's power means that all wizards within 5 miles are aware of a powerful casting.
