Talisman of Summoning

You touch a piece of nonmagical jewelry worth at least 500 gp such as a ring, an amulet, or a bracelet. For the duration of the spell, a creature which is wearing the object you touched can use a bonus action to summon you, causing you to appear in an unoccupied space within 10 feet of the creature. Once you are successfully summoned, the spell ends and the object disintegrates into motes of light.
