Amulet of the Living Statue

Uncommon Wondrous Item

Stone Resilience. A creature wearing this amulet becomes immune to becoming Petrified.
Walking Statue. If this amulet is put on a Petrified creature the effects of the petrification are surpressed as long as they are wearing the amulet. However, while the petrification is surpressed, it causes the creature to become vulnerable to Bludgeoning damage. If they are no longer wearing the amulet, the creature becomes Petrified again after one minute. A creature can be fully cured of the (surpressed) petrification by any spells or cures that would normally cure petrification while wearing the amulet.
