corvin

Unyielding: When reduced to 0 HP, Corvin can make a DC 16 Constitution saving throw. On a success, he drops to 1 HP instead (once per long rest).

Claw (Melee Weapon Attack): +10 to hit, reach 5 ft., one target. 2d8 + 7 slashing damage.

Twin Back Cannons (Ranged attack): corvin fires both cannons mounted on his shell at two targets within 120 feet.
Ranged Weapon Attack: +10 to hit, range 120/480 ft., two targets. 2d8 bludgeoning damage each. Targets hit must succeed on a DC 14 Dexterity saving throw or be knocked prone and pushed 10 feet away.

Broadside Barrage (2 Charges): Corvin unleashes a devastating volley from his cannons in a 60-foot cone. Each creature in the area must make a DC 15 Dexterity saving throw, taking 4d8 bludgeoning damage on a failed save, or half as much on a success.

Shell Defense: As a bonus action, corvin can withdraw into his shell, gaining +4 AC and advantage on Strength and Constitution saving throws until he emerges (as an action). While in his shell, he is prone and cannot attack

Intimidating Roar(2 charges): Let out a fearsome pirate bellow. Creatures of his choice within 30 feet must succeed on a DC 16 Wisdom saving throw or be frightened until the end of his next turn.

Living Ship Shell: The tortle’s shell is partially alive, with barnacles and coral that animate to protect him. Once per encounter, corvin can cause the shell to sprout spiked coral or barnacle clusters that deal 2d6 piercing damage to any creature that hits him with a melee attack until the start of his next turn.

Shell Shield(2 charges): When hit by an attack, Captain Ironback can use his reaction to interpose his massive shell, reducing the damage by 15.

Cannonball Counter(2 charges): When a ranged attack targets Corvin, he can use his reaction to fire a quick cannon shot at the attacker (make a twin back cannons attack).

Wave Step(2 charges): When forced to make a Dexterity saving throw to avoid an effect, Corvin can use his reaction to gain advantage on the save by shifting his weight and bracing like a crashing wave.
