Breath Weapons (Recharge 5-6)

The dragon uses one of the following breath weapons: * Shard Breath. The skeleton exhales a 15-foot cone of bone shards. Each creature in that area must make a DC 13 Dexterity saving throw, taking 18 (4d8) piercing damage on a failed save, or half as much damage on a successful one. * Noxious Breath. The skeleton exhales a 15-foot cone of gas. Each creature in the area must succeed on a DC 13 Constitution saving throw or become poisoned for 1 minute. A creature poisoned in this way can repeat the saving throw at the end of each of its turns, ending the poisoned condition on itself on a success.
