Clan War League (CWL) is the monthly league competition where clans fight a round-robin of wars against seven other clans for league medals and promotion. Knowing the signup and war-day window matters because rosters and upgrades are best planned before it opens.

Clan competition and League rewards depend on participation and results. Check the live reward panel before committing resources; prices, quantities, and account progress are not inferred from the season artwork.
Keep the seven-war roster reliable by arranging hero availability and donation coverage before starting upgrades that would disrupt your assigned attacks.
Confirm your next war assignment with the leader, prepare a backup attacker, and schedule long hero upgrades around the wars you have committed to play.

How often it runs: Monthly, opening at the start of each season and running for roughly the first ten days including signup.
How a smaller clan should choose between 15v15 and 30v30, rotate seven days of attacks so reliable members reach the 8-star full-medal threshold, pair attackers with bases, and award bonus medals fairly.
