When you take damage from a creature that is within 10 feet of you, you can take a Reaction and expend a Hit Point Die to unleash draconic energy in a 10-foot Emanation originating from you. Each creature you choose in the Emanation makes a Dexterity saving throw against your spell save DC. On a failed save, a creature takes damage equal to two rolls of your Hit Point Die plus your Constitution modifier, or half as much damage on a successful one. The damage is your choice of Acid, Cold, Fire, Lightning, or Poison.
