This is a set of 20 quests available daily where you can obtain League Daily EXP Books, which can give you a lot of EXP when used. These quests are available every day, after the daily reset at 5:00 AM GMT+8.
Like other quests in the game, these quests can be completed automatically without any input from you. Just tap the League Daily quest from the quest list and leave your game running until it is completed. Due to the large amount of EXP you can obtain from this effortless task, it’s recommended to do this as part of your daily routine, especially if you’re playing the game regularly.
