Update History

Major changes

Added “Reroll History”

  • The most recent 5 items rerolled on that item acquisition screen will be recorded.
  • You can select any of those 5 items to restore.
    After restoring, you will not be able to reroll during that item acquisition.
  • The reroll history screen allows batch reroll of 5 items at a time.
  • While using the batch reroll, reroll confirmation will no longer be performed even when high rarity items appear.

Revision of the rarity calculation method for lab parts

  • Nothing will be changed regarding the contents of lab parts or drop specifications.
  • Only the visual rarity will be changed.
  • Originally, lab parts have an internal rarity of ★1~5 for each of up to 2 parameters, and the part rarity is determined from the total rarity. (The unique ability is ★5, and the maximum total is 10.)
    Originally, this total should have been multiplied by 0.7 to determine the final part rarity, but due to a bug, it was not multiplied by 0.7.
  • As of v1.0.11, the total rarity is displayed with the number of stars multiplied by 0.7. As a result, a part with a parameter rarity of 5 will be displayed as 5*0.7=3.5=★4 when viewed by part rarity.

Added New item “Tag of Onslaught”

  • Starting with v1.0.11.9, a new mission will be added to each dungeon to obtain “Tag of Onslaught”.
  • The achievement condition for each dungeon is to get the high score in that dungeon.
  • The “Tag of Onslaught” will be exchangeable for keystones for higher difficulty challenges from the store menu to be added in v1.1.0.
    (As of v1.0.X, there is no use for this item, so please keep it when you have acquired it.)
