Seasons are week-long competition periods, and players are rewarded with chests at the end of each season. For those in the Grandmaster League, the ranking at the end of the season determines what rewards are earned. For those outside of the Grandmaster League, the highest League level achieved during that season determines what rewards are earned. Seasons end at midnight UTC on Monday mornings. A player who does not fight any League battles during a season will not get any rewards for that season.
Tabulated below are the rewards earned for each best League reached during a season.
