Actions

Multiattack. Ashgarlyth makes three attacks: one with his bite and two with his claws.
 
Bite. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 16 (2d10 + 5) 210+5 piercing damage.
 
Claw. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) 2d6+5 slashing damage.
 
Breath Weapons (Recharge 5–6). Ashgarlyth uses one of the following breath weapons.

• Lightning Breath. Ashgarlyth exhales lightning in a 60-foot line that is 5 feet wide. Each creature in that line must make a DC 15 Dexterity saving throw, taking 55 (10d10) lightning damage on a failed save, or half as much damage on a successful one.


• Repulsion Breath. Ashgarlyth exhales repulsion energy in a 30-foot cone. Each creature in that area must succeed on a DC 15 Strength saving throw. On a failed save, the creature is pushed 40 feet away from the dragon.

Change Shape. Ashgarlyth magically polymorphs into a humanoid or beast that has a challenge rating no higher than his own, or back into his true form. He reverts to his true form if he dies. Any equipment he is wearing or carrying is absorbed or borne by the new form (Ashgarlyth's choice).
 
In a new form, Ashgarlyth retains his alignment, hit points, Hit Dice, ability to speak, proficiencies, Legendary Resistance, lair actions, and Intelligence, Wisdom, and Charisma scores, as well as this action. His statistics and capabilities are otherwise replaced by those of the new form, except any class features or legendary actions of that form.
