Instructions
Attack with multiple ships. The Sarek warrior ship is designed to handle nearly any ship you can throw at it in one-on-one battles. You can overwhelm the ship with multiple ships, even if it means several casualties on your side.
Upgrade the offensive and defensive equipment of your ships. Even with upgrades, your ships won't be able to contend with a Sarek warrior ships one-on-one, but you can significantly increase the time it takes for the ship to destroy your ships while also increasing the damage done to the Sarek warrior ship.
Spread your ships on both sides of the Sarek warrior ship. The ship has a very slow fire rate, but it will unleash a devastating blow each time it fires. Limit how quickly the ship can fire by spacing out your ships, forcing it to move anytime it wants to fire.
