Actions

Multiattack

action

The dragon turtle makes three attacks: one with its bite and two with its claws. It can make one tail attack in place of its two claw attacks.

Bite

action

Melee Weapon Attack: +13 to hit, reach 15 ft.. Hit: 26 (3d12 + 7) piercing damage.

Claw

action

Melee Weapon Attack: +13 to hit, reach 10 ft.. Hit: 16 (2d8 + 7) slashing damage.

Tail

action

Melee Weapon Attack: +13 to hit, reach 15 ft.. Hit: 26 (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

action

Recharge 5–6. 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) fire damage on a failed save, or half as much damage on a successful one.
Being underwater doesn't grant resistance against this damage.
