Event Guide[]
- Stages are likely required to be cleared twice. If teachers don't have the upgraded event students; It's easier to clear the stage twice: to get the 3★, bonus student drops, and thus the maximum reward.
- Once an area has been perfectly cleared, at 3★. The stage reward given is always the highest recorded drop, including the bonus from the students.
- Using the "Skip or Rush" function will record the highest drop.
- In this event, teachers can farm a lot of items:
