Before the enemies could fire their arrows, Zaos held his sword tightly and concentrated wind magic on the blade. At the same time the first arrow was fired, Zaos swung and sent the wave of wind toward the enemies. He didn't concentrate enough to make the wind cut them, but It repelled the arrows and also made the enemies fall.
After that, Zaos and the others approached and then finished the enemies off. Zaos saw the catapult right in the middle of the ship, but he didn't see many oil barrels around. It seemed that Ferdinand considered that some of his men would lose their ships and decided to evenly spread the oil between many ships. That was quite odd since it would require him to have a huge number of catapults.
"Position the catapults and then attack the other pirate ships!" Erean said. "Zaos, go check if there is anyone hiding inside it."
