Bound. The guardian is magically bound to its creators soul. As long as the guardian lives it can find its master. the master can telepathically call the guardian to travel to it or expend a 7th level or higher spell to summon it. the guardian knows the distance and direction to its master. If the guardian is within 80 feet of the amulet's wearer, half of any damage the wearer takes (rounded up) is transferred to the guardian.

Spell Storing. A spellcaster who owns a guardian can cause the guardian to store one spell of 5th level or lower. To do so, the wearer must cast the spell on the guardian. The spell has no effect but is stored within the guardian. When commanded to do so by the wearer or when a situation arises that was predefined by the spellcaster, the guardian casts the stored spell with any parameters set by the original caster, requiring no components. When the spell is cast or a new spell is stored, any previously stored spell is lost. Alternatively if the master perishes and the guardian is within 10 ft the master can take control assuming the spell slot is unfilled.
