Main Story Exchange Post

Main Story Exchange Post is a recurring event that comes with each new Main Story Chapter release, since the introduction of Chapter 12 on 07/11/2023.

For the event period, a variance of Orca Supplies () currency will be added into items drop list in every Main Story stage that has item drops. Event period varies depending on the size/total parts of the Chapter.

Note: The event currency will be removed after event ends.

Farming Tips

The drop of the currency is depending on the number of waves in the stage. Each wave has a chance to drop 0~2 currency. Thus, try to farm in the stage that has 4 or more waves and with the shortest clear time you could achieve.
