Actions

Multiattack. The dragon turtle makes three attack:: one with its bite and two with its claws. It can make one tail attack in place of its two claws attacks.   Bite. Melee Weapon Attack: +13 1d20+13 to hit, reach 15 ft., one target. Hit: 26 (3d12+7) 3d12+7 piercing damage.   Claw. Melee Weapon Attack: +13 1d20+13 to hit, reach 10 ft., one target. Hit: 16 (2d8+7) 2d8+7 slashing damage.   Tail. Melee Weapon Attack: +13 1d20+13 to hit, reach 15 ft., one target. Hit: 26 (3d12+7) 3d12+7 bludgeoning damage. If the target is a creature, it must succeed on a DC 20 Strength saving throw or be pushed up to 10 feet away from the dragon turtle and knocked prone.   Steam Breath (Recharge 5-6) 1d6 . The dragon turtle exhales scalding steam in a 60-foot cone. Each creature in that area must make a DC 18 Constitution saving throw, taking 52 (15d6) 15d6 fire damage on a failed save, or half as much damage on a successful one. Being underwater doesn't grant resistance against this damage.
