Multiattack

The dragon makes three attacks; one with its bite and two with its claws.

Bite

Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 13 (2d6 + 6) piercing damage plus 3 (1d6) poison damage.

Claw

Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 13 (2d6 + 6) slashing damage.

Poison Breath (Recharge 5-6)

The dragon exhales a cone of black poison gas in a 30-foot cone. Each creature in that area must make a DC 16 Constitution saving throw, taking 45 (13d6) poison damage on a failed save and becoming poisoned if it is a creature. The poisoned condition lasts until the target takes a long or short rest or removes the condition with lesser restoration or comparable magic. If the save is successful, the target takes half damage and is not poisoned.
