Traits

- Keen Senses: The dragon has advantage on Wisdom (Perception) checks that rely on sight, hearing, or smell.
Actions
- Multiattack: The dragon can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.

- Lightning Breath (Recharge 5-6): The dragon exhales lightning in a 90-foot line that is 5 feet wide. Each creature in that line must make a DC 19 Dexterity saving throw, taking 63 (18d6) lightning damage on a failed save, or half as much on a successful one.
- Frightful Presence: Each creature of the dragon’s choice that is within 120 feet of the dragon and aware of it must succeed on a DC 17 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

- Wing Attack (Costs 2 Actions): The dragon beats its wings. Each creature within 15 feet of the dragon must succeed on a DC 19 Dexterity saving throw or take 13 (2d6 + 6) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed.
