Traits
If the dragon fails a saving throw, it can choose to succeed instead.

Actions
The dragon makes one Bite attack and two Claw attacks.
Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 17 (2d10 + 6) piercing damage plus 7 (2d6) psychic damage.
Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 10 (1d8 + 6) slashing damage.
The dragon exhales a wave of psychic dissonance in a 60-foot cone. Each creature in that area must make a DC 18 Intelligence saving throw. On a failed save, the creature takes 42 (12d6) psychic damage, and until the end of its next turn, when the creature makes an attack roll or an ability check, it must roll a d6 and reduce the total by the number rolled. On a successful save, the creature takes half as much damage with no additional effects.
