All clans are divided into 6 Leagues: Bronze, Silver, Gold, Champion, Legend and Divinity. Bronze, Silver and Gold leagues are also divided into 4 subgroups.
On the first run, all clans that meet the conditions for participation are assigned a starting ranking and a league is determined based on the average strength of the 70 most pumped heroes of each player in the clan.

Each league has a certain rating value.
If a clan gains the required amount of rating of the league above, it moves to that league.
If the clan's rating falls below the threshold value of the current league, the clan's league changes to a league lower. The higher the league, the more valuable the rewards will be.

A clan's rating is awarded based on the results of a battle. For a victory the rating is always added, for a defeat and a draw the rating is always reduced. For each league the basic rating values are the same: +35 rating for a victory, -27 rating for a defeat (including a draw).

At the end of the Season, each clan will receive a special award. The higher the League, the more awards!
The Season lasts for 3 months. Then clans will fight for new territories and League rankings will be updated.

If a clan is disbanded, it will disappear from the ranking and all its history will be deleted.
