Actions
- Multiattack: The dragon makes three attacks: one with its bite and two with its claws.

Each creature in that area must make a DC 18 Constitution saving throw, taking 54 (12d8) necrotic damage and being blinded for 1 minute on a failed save, or half as much damage and not blinded on a successful one. A blinded creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. This ability can only be used during nighttime hours.
