Cargo ship key.

[Eartharies]

Make a key that drops from harbor. It will be you spawning in the water outside of cargo swimming towards and boarding it to fight the existing bandits. A crate in the bottom of the cargo will be present right clicking on it will cause waves of bandits to fly in and drop onto the ship.
If you have any ideas to add to this please be my guest i would just love to see another wave style key.
