What happened

The official notice was posted September 11 at 19:05 JST and scheduled completion by 20:40 JST.

The publisher says the work does not require a maintenance shutdown, although some content can be briefly unavailable.

The practical change: Restart the client before checking the corrected values or rewards, especially if it remained open while the server patch was applied.

What is confirmed

  • Extract Energy awakening options are corrected.
  • The Specialization III Deep Sea critical-damage value is corrected.
  • Issues involving a Transcendent chest, engraving reset, Harmony value and Coco rewards are included.
  • The notice recommends restarting the game after the patch.

What this means for players

Displayed skill or reward behavior can differ until the client refreshes its server data.

A brief content interruption around the patch window does not by itself indicate extended maintenance.

What is still unconfirmed

The notice does not state that every skill, reward or inventory issue is resolved.

What to do next

  1. 01
    Restart the client.
  2. 02
    Retest the named skill or reward.
  3. 03
    Use the official support route if the corrected state still does not appear.
