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:
    • Materials (Ooparts)
      There are 4 types of materials that teachers are able to obtain and each can be obtained from tier 1 to tier 4. There is no event bonus for these materials.
      • WolfseggWolfsegg 3⁠ ~ Quest 1 (T1/2) / Quest 5 (T2/3) / Quest 9 (T2/3/4)
      • VoynichVoynich 3⁠ ~ Quest 2 (T1/2) / Quest 6 (T2/3) / Quest 10 (T2/3/4)
