Use Aether attacks and your champions' Aether attacks for maximum damage. Each time a character gets killed, the ship will lose an amount of health equal to that character's maximum hit points. This will happens for both spawned characters and for new characters. Focus on attacking the easiest enemy to quickly destroy the enemy ship. To do the maximum damage possible, use Aether and champions' Aether attacks. Stand on the Aether platforms in the middle of a battle to charge your Aether faster, and earn Aether each time you get hit.
