War points are points that are rewarded to your clan after clan warring and sinking an enemy fort.

1) To get points from a clan, they must have at least 25% of your clan's warpoints. (i.e. a 2000 WP clan will get nothing for defeating a 400 WP clan)

2) The number of points you get is either 10 Warpoints or 25% of the difference in warpoints, whichever is greater. (i.e. a 1,000 WP Clan taking down a 3,000 WP Clan would get 500 WP whereas the 3,000 WP Clan would get only 10 WP for sinking the 1000 WP Clan).

1 war point is also given for every 10 ships sunk by your fortress.

At present, there is no functionality for war points other than to determine clan rankings and to aid the clan's bragging rights.
