Captain Ruban Acer is a pirate encountered during the quest The Red Reef. He is the captain of the ship The Bark of the Bight, and directly attacks the player with ranged attacks. If Mister U. is slain, Captain Ruban will stop attacking the player and man the helm of his ship. If both Mister U. and Captain Ruban are slain, The Bark of the Bight will stop moving entirely.
