The spell required several ingredients such as various herbs, powders, crushed pills, and blood of the caster. However, the most important involved the soul of the caster. The spell is cast when the target is in the immediate area by closing the jar used. The effect is instantaneous, and is marked by a flash of bright light. Any captured beings will be transformed into greyish liquid. The beings bound by the spell are trapped in the jar, but if it is disturbed both will become free.
