Direct answer: The October 28 Version 2.3 maintenance will reset Mystic Keys, Chaos Keys, and weekly Raid reward claim counts. After the update, the keys and weekly claims are replenished only by the amount used before the update. Knighthood Boss Battle becomes unavailable after the October 26 weekly reset at 07:00 UTC, and the new season begins after the October 28 maintenance.
What resets during the October 28 maintenance?
- Mystic Keys.
- Chaos Keys.
- Weekly Raid reward claim counts.
Netmarble says the post-update replenishment is limited to the amount used before the update. This notice does not promise a full extra stock beyond that rule.
When is Knighthood Boss Battle unavailable?
The current Knighthood Boss Battle season becomes temporarily unavailable after the weekly reset on October 26, 2026 at 07:00 UTC. The new season begins after the October 28 maintenance. The notice does not provide a full new-season reward table or a replacement banner.
What should players check before the downtime?
- Record current Mystic Key and Chaos Key counts.
- Check how many Weekly Reward claims remain and whether a planned clear can be completed before maintenance.
- Do not treat the October 26 Knighthood reset as a normal available challenge window after 07:00 UTC.
- Keep delayed or expected rewards out of the budget until they appear in the mailbox or account.
What is not confirmed here?
This notice confirms scheduling only. It does not confirm new banner rates, pity changes, a complete Version 2.3 reward table, or a post-October-28 hero. Use the separate Developer Notes #21 summary for the announced systems and its future-plan caveats.
