Shatterbolt
Weapon (arrow or bolt), uncommon

This piece of magic ammunition is tipped with an accretion of brittle stone. The shatterbolt explodes into shards of jagged rock when it impacts something. Each creature within 10 feet of the explosion must succeed on a DC 13 Dexterity saving throw or take 3d4 piercing damage. A creature reduced to 0 hit points by this damage is stable but petrified until freed by the greater restoration spell or other magic.

As if the earth itself were a quiver, the elementalist pulled an arrow from the ground. She knocked it and fired skyward, striking the harpy with an explosion of stone and elemental magic. Its petrified body plummeted to the ground, shattering at her feet.
