Parry. The Admiral adds 2 to its AC against one melee attack that would hit it. To do so, the captain must see the attacker and be wielding a melee weapon.

The Admiral can take three legendary actions per round. 

Attack: The Admiral can choose to attack with one of it's weapons.

Chain Wrap: costs 2 legendary actions. The Admiral attacks with his Flame Chain Melee Weapon Attack: +5 to hit, reach 20 ft (5 feet less for each use of chain wrap used). Rather than striking the enemy however the target must make a strength saving throw DC 16. On a failed save the character is restrained and takes 2d6 fire damage. At the end of their turn the creature can attempt the saving throw again to break free of the chains or an allied creature can use an action to remove the chains. If the creature remains restrained it takes an additional 2d6 fire damage. For each use of chain wrap the Admiral's attacks with his Chains and Anchor have their reach reduced by 5.
