This article is updated with the Spring 2019 update that changed the reward system.
Introduced on the October 2018 update, Clan War Leagues - also know as CWL - is a type of Clan Wars where your clan will battle against 8 clans.
On CWL, your clan joins a pool of 8 clans to battle against each other on a series of 7 consecutive 24-hour wars.
CWL happens once every month. This event is always previously announced on the events tab with a countdown. Once the sign-up period starts, the leaders of your Clan have 2 days to choose the members and sign-up your clan.
The minimum number of members to participate in this CWL is 15.
Starting in April 2019, the Clan can sign-up to 15vs15 or 30vs30 wars. After the sign-up, there is no way to change, and you must go through the 7 days of war with that size. Clans on the Champions League can only make 15vs15 wars.
Even though the war size is 15 or 30 members, you can pick more players to the CWL, but later-on you must select only 15 or 30 to go to the war. Since the event is seven 24-hour wars, you can substitute members every day. Think about this as a football team: if the player is not participating as he should, he can be replaced.
Tip: we recommend signing-up all members to the CWL, so even players that won't participate will get League Medals for the victories.
The whole event lasts a total of 8 days, with the first day being a preparation day followed by seven 24-hour wars.
On the first day of preparation, you have to fill up the clan castles with defense troops. But this doesn't mean we will have only one preparation day; there are 7 preparation days. Once a war starts, the preparation for the next war begins as well, where not only you have to fill up the Clan Castles, but also choose the members that will participate in the next one. This is how you can replace bad players for the next war. The moment a war ends, the next one starts immediately.
Another significant change from conventional wars is the fact that each member can only make one attack per war, making every attack very important. If a player doesn't attack, an enemy village will not be attacked at all.
The matchmaking is based only on the current clan's League. It's a ladder-based war. There is no war-weight, Town Hall levels, Engineered Bases, nothing, only the War League your clan is matters, making this a genuinely skill-based game mode.
One quick note, the first time you enter on a CWL, your clan will automatically join a specific league. This League is based on the 15 strongest players of your clan. The higher your League is, the stronger your clan and enemies should be.
There were many complaints of unfair matchmaking on the first CWL event, but as soon as the stronger clans level up, the battles started to be fair. It takes some time, but eventually, you will be matched against clans with similar strength as your clan.
A Clan can only participate in one war type at a time: Clan War Leagues, regular Clan Wars, or a Friendly War. If your Clan decides to not join in CWL, it can call regular Clan Wars without issues.
A member that was not selected to join the CWL can also leave the Clan, join another Clan, and participate in their Wars; he will not be ineligible.
Once the Clan War League is over, the clan(s) with more stars will be promoted to the next League. The worst ones, demoted.
The number of clans promoted/demoted depends on the current League the clan is.
|War League(s)||Clans Promoted||Clans Demoted|
|Bronze I & Bronze II||3||1|
|Silver II - Crystal II||2||2|
|Crystal I - Chapion II||1||2|
The number of League Medals you get on Clan War Leagues depends on your League, on the final position of your Clan on the competition and on the number of Stars you've obtained during the League. If you didn't attack in the War but was included on the roaster, you will get medals as well.
On this table you can find the maximum number of League Medals you can obtain based on the league and final position of your clan:
|War League||1st Place||2nd Place||3rd Place||4th Place||5th Place||6th Place||7th Place||8th Place|
However, you will only get a the maximum reward if you obtain 8 or more Stars during the event. Here is the list that shows the percentage of League Medals you will get based on how many Stars you have earned:
|Stars Earned||% of Medals Received|
It's important to note that even if you didn't earn any Star (or didn't attack at all), you would get a small number of League Medals (20%). For this reason, we recommend signing up all members of your clan, even if some members will not participate in the actual wars.
Just by being on the roster will give you 20% of the medals. Each star will provide you with an extra 10%, limited by 8, which ends up awarding you 100% of the possible League Medals.
Here is an example: your clan got the first place on Master II. The maximum number of League Medals each member can get is 346. If a member got 3 Stars, he would get 50% of this bonus, 173 League Medals. If a member got 10 stars, he would get 100% of the bonus, 346 League Medals.
In the end, there is one last cool feature: the Leader or Co-Leaders can give extra League Medals to the players they think deserve the most.
A table with complete stats of the participating members will be shown, and the leaders will choose who is going to get the bonus.
The number of League Medals on each bonus and the number of players eligible to receive it are based only on your League.
On this table you will find the number of League Medals each bonus has and the number of bonuses rewarded. Extra bonuses will be granted to each victory your clan had on CWL:
|War League||Number of Guaranteed Bonuses||League Medals per Bonus|
Any player can be selected, even the ones that didn't attack or left the clan.
