Wondrous Item

Very Rare

Sending Stones usually come in pairs, with each smooth stone carved to match the other so the pairing is easily recognised. While you touch one stone, you can use an action to cast the sending spell from it. The target is the bearer of the other stone. If no creature bears the other stone, you know that fact as soon as you use the stone and don't cast the spell.   Once sending is cast through the stones, they can't be used again until the next dawn. If one of the stones in a pair is destroyed, the other one becomes non-magical.
