The Daily Tasks feature is optional quests for each summoner set differently on a daily basis. In return, the game will award each player with Brave Points based on the number of tasks or quests completed for the day and in turn be exchanged for some rewards. Please remember that each task and progress in a day will reset upon changing, so be sure to complete those quests before it ends for the day.
