The game has four quest types: daily & weekly, one-time, and Guild quests.
Daily and Weekly Quests
You can find the complete list of daily and weekly quests and the corresponding rewards in the Daily quests tab. To open it, click the calendar icon in the upper-left corner of the main game screen.
To open daily or weekly quests, select the corresponding tab.
Click Go for it! next to the desired quest to access the game mode, where you can complete it.
You can get team EXP points for completing specific daily tasks. When you reach the maximum team level, the reward for completing these quests changes. Instead of EXP points, you will get Honorable Guardian Boxes that contain random items.
One-time Quests
To view one-time quests and claim your rewards, click Quests at the bottom of the main game screen.
Click Go for it! next to the desired quest to access the game mode, where you can complete it.
Guild Quests
Guild Quests unlock with the Guild feature at team level 30. You can learn more about Guild Quests here.
When Guild Quests become available, the Guild Quests button appears in the Daily quests tab.
Once you click the shortcut, you will be redirected to the Guild Quests menu.
