After each battle, regardless of whether it’s been victorious or not, player gains activity points calculated from the damage dealt during the battle.
100,000 damage points = 1 activity point*
*Damage points are rounded
The number shown on the player profile and clan rating is the total amount of points obtained for the previous week.
Clan rating is calculated from activity points gained by all clan members. Points earned outside the clan don’t count.
*If you leave a clan, points, gained while you were a member, won’t be subtracted from the clan’s weekly activity.
