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 attack +12 to hit, reach 2 sqr. (3m), one target. 37 (5d10+7) piercing damage. Claw: melee attack +12 to hit, reach 1 sqr. (1.5m), one target. 27 (5d6+7) slashing damage. Tail: melee attack +12 to hit, reach 3 sqr. (4.5m), one target. 32 (5d8+7) bludgeoning damage. Frightful Presence: Each creature of the dragon’s choice that is within 24 sqr. (36m) 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. 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): The dragon uses one of the following breath weapons.

• Lightning Breath: The dragon exhales lightning in a 18 sqr. (27m) line that is 1 sqr. (1.5m) wide. Each creature in that line must make a DC 19 Dexterity saving throw, taking 66 (12d10) lightning damage on a failed save, or half as much damage on a successful one.
• Repulsion Breath: The dragon exhales repulsion energy in a 6 sqr. (9m) cone. Each creature in that area must succeed on a DC 19 Strength saving throw. On a failed save, the creature is pushed 12 sqr. (18m) away from the dragon. Change Shape: The dragon magically polymorphs into a humanoid or beast that has a challenge rating no higher than its own, or back into its true form. It reverts to its true form if it dies. Any equipment it is wearing or carrying is absorbed or borne by the new form (the dragon’s choice). In a new form, the dragon retains its alignment, hit points, Hit Dice, ability to speak, proficiencies, Legendary Resistance, lair actions, and Intelligence, Wisdom, and Charisma scores, as well as this action. Its statistics and capabilities are otherwise replaced by those of the new form, except any class features or legendary actions of that form.

Legendary

This creature can take 3 legendary actions. It can take one legendary action at a time at the end of another’s creatures turn. This creature regains spent legendary actions at the start of it’s turn. Detect: The dragon makes a Wisdom (Perception) check. Tail Attack: The dragon makes a tail attack. Wing Attack (Costs 2 Actions): The dragon beats its wings. Each creature within 2 sqr. (3m) of the dragon must succeed on a DC 20 Dexterity saving throw or take 14 (2d6+7) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed.
