**Legendary Resistance (3/Day)**. If the dragon fails a saving throw, it can choose to succeed instead.
- Actions
**Multiattack**. The dragon can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.
**Bite**. Melee Weapon Attack: +15 to hit, reach 15 ft., one target. Hit: 19 (2d10+8) piercing damage plus 9 (2d8) acid damage.
**Claw**. Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 15 (2d6+8) slashing damage.
**Tail**. Melee Weapon Attack: +15 to hit, reach 20 ft., one target. Hit: 17 (2d8+8) bludgeoning damage.
**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 19 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. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the dragon's Frightful Presence for the next 24 hours.
**Acid Breath (Recharge 5-6)****. The dragon exhales acid in a 90-foot line that is 10 feet wide. Each creature in that line must make a DC 22 Dexterity saving throw, taking 67 (15d8) acid damage on a failed save, or half as much damage on a successful one.
