Stone of Protection (5e Equipment)
From D&D Wiki
Wondrous item, rare (requires attunement)
This round stone is imbued with protective magic. While it is on the user's person and they are subjected to an attack or effect that deals damage, the damage is instead dealt to the stone. Attacks or effects that deal psychic damage bypass this property.
While being worn or carried, the stone has 12 hit points, a damage threshold of 3, and resistance to all damage types except force. As long as it still has hit points remaining, casting the mending cantrip upon it will restore 6 hit points to the stone. If the stone is reduced to zero hit points, it shatters, becoming inert and non-magical. Any leftover damage does not carry over to the user.
If the stone is targeted by or takes damage dealt by the disintegrate spell, it is immediately destroyed.
