The Line of Defense icon can be found on the right side of the main screen.
The event lasts for 12 days. It is available in three difficulties. Although there is no limit to the number of times you can enter the Stages, you can only claim the rewards for each Stage once per day. Unclaimed rewards will be retained, but not accumulated for the same Stage.
You can select up to 10 different Heroes to enter the Stage each time. You can't select the same Hero more than once, nor can you change your Heroes during the battle.
Every player will start with an initial HP amount.
The monsters will enter the Stage via the Start Portal and move towards the End Portal. Some HP will be deducted from you for every monster that reaches the End Portal successfully.

The ring around the icon will count down to the next wave of monsters.
A special prompt will be displayed when a Boss spawns in the stage.
