Balance changes and fixes

  • Some chips and dedicated skills are due for adjustments; this roundup does not specify the new individual values.
  • ミストリア / 安眠ミサイル and エーテリファル / 永眠ミサイル: adjacent allies’ dedicated-skill damage is planned to lose the slow and sleep effects.
  • The effect on normal attacks is unconfirmed; the wiki’s additional interpretation is not treated as a confirmed rule.
  • A ホルリン-family 縦横無尽 issue that moves allies outside the placement area is scheduled to be fixed.
  • Dedicated-skill descriptions are revised. Gift-box collection is planned to be capped at 20 times per person per week.
  • Chapters 24–28 are listed for enemy-placement changes and additional enemies.

What to check before the update

  1. Record your highest Season 2 difficulty so you can compare it after the transition.
  2. Keep the current descriptions of your chips and dedicated skills for comparison with the updated in-game text.
  3. Check the in-game schedule and entry requirements before joining an event.
