Claw. Melee Weapon Attack: +19 to hit, reach 25 ft., one target. Hit: 23 (3d8 + 10) slashing damage. On a hit, if the target is Huge or smaller, it is grappled (escape DC 20) and is restrained until this grapple ends. The dragon has two claws, each claw can grappled one target at a time.

Tail. Melee Weapon Attack: +19 to hit, reach 40 ft., one target. Hit: 26 (3d10 + 10) bludgeoning damage. On a Hit, the target must succeed on a DC 27 Strength saving throw. On a failed save, the target is knocked prone. If a target fails its saving throw by 5 or more, it is also pushed up to 60 feet away from the dragon. If a pushed target strikes a solid surface, the target takes 3 (1d6) bludgeoning damage for every 10 feet it was pushed. If the target is pushed at another creature, that creature must succeed on a DC 27 Dexterity saving throw or take the same damage and be knocked prone.

Majestic Presence. Each creature of the dragon's choice that is within 150 feet of the dragon and aware of it must succeed on a DC 27 Wisdom saving throw. On a failed save, a creature is stunned for 1 minute. A stunned 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.

Breath Weapons (Recharge 5–6). The dragon uses one of the following breath weapons:

Lightning Breath. The dragon exhales acid in a 600–foot line that is 20 feet wide. Each creature in that line must make a DC 26 Dexterity saving throw. On a failed save, a creature takes 110 (20d10) lightning damage. On a successful save, the creature takes half as much damage.
