Sacred Vial

Potion, uncommon

This glimmering crystal vial contains holy water. The vial magically refills itself each dawn.

As an action, you can throw the full vial at a solid surface within 60 feet, shattering it and creating a fleeting pearlescent mist that forces all undead and fiends in a 20-foot-radius sphere centered on the vial to make a DC 15 Constitution saving throw. On a failed save, a creature takes 4d6 radiant damage. On a successful save, the creature takes half as much damage.
