Erupting Cinders

A tiny star materializes in your hand. It flicks with Starlight energy with an intense glow, only to die down just as quickly. You scatter the cindered ashes through the winds, and that very same cinders pursue your foes, exploding in contact.. Select up to 3 creatures in range, they must make a Dexterity saving throw. A target takes 4d6 Radiant Damage and 3d6 Fire Damage on a failed save, or half as much damage on a successful one.
