Actions

Multiattack: The dragon makes two attacks: one with its bite and one with its claws.

Bite: Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: (2d10 + 4) piercing damage plus (1d8) cold damage.

Claw: Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: (2d6 + 4) slashing damage.

Cold Breath (Recharge 5-6): The dragon exhales an icy blast in a 30-foot cone. Each creature in that area must make a DC 14 Constitution saving throw, taking 18 (4d8) cold damage on a failed save, or half as much damage on a successful one.
