Alliance Raids

An alliance raid is five tiers of co-operative fight against a fixed enemy. The leader schedules one, members commit ships and contribute supplies, and the whole lot sails as one line of battle.

Every captain who takes part is paid the same base reward. What you contributed only moves the bonus on top, so a small contribution is still worth making.

Each tier can be won once a day per alliance.
