Eye Burn

You sting the eyes of a creature attacking you. The target must make a Constitution saving throw (a creature with Blindsight or Immunity to the Blinded condition succeeds automatically). On a failed save, the target has the Blinded condition until the end of the turn. On a successful save, it must subtract 1d4 from the triggering attack roll. The target automatically succeeds on its saves against your subsequent casting of this spell for 24 hours.
