A soul jar is used to capture souls either by creatures with a soul bind magical ability or by transferring the soul from a black sapphire that contained a soul as a result of the soul bind spell. If transferred from the sapphire by holding it against the jar's lid, the sapphire is destroyed half of the time. The jar can contain one soul. A resurrection spell can bring back to life someone whose soul is trapped in the soul jar.
