Mongil: Star Dive’s temporary maintenance on August 26, 2026 finished half an hour early, at 01:30 (UTC) on August 27 rather than 02:00. Compensation is Starlight Crystal ×100, and it is sent by mail to every Diver who logs in between the end of maintenance and August 29, 2026 at 14:59 (UTC) — log in before that and it arrives, miss it and it does not.
Conquest Ranking Season Moved
The current Conquest Ranking season now ends September 29, 2026 at 00:00 (UTC) instead of September 26 at 15:00 — three extra days, and a change of both date and time of day for anyone timing a final push.
New Guidebook Improvements
- Artifact level missions now complete retroactively when the required artifact level has already been reached.
- Monster defeat, gathering, mining and monster capture missions start counting once that chapter’s login mission rewards are claimed.
- The move button on equipment crafting missions now shows the equipment it refers to.
- Some missions gained rewards: equipment enhancement materials, character level-up materials, Gold, artifacts and equipment crafting materials. Accounts that already cleared those missions receive the additions by in-game mail.
Issue Fixes
- Two items both named “Gourmand’s Apron” no longer share a name — the one in the Gourmand’s Grand Banquet set is now Grand Banquet Apron.
- Neutralizing a Special Attack in Legendary Conquest no longer succeeds outside the special attack pattern phase.
- Fixed dialogue log lines in Brisshell’s Epic Quest that were attributed to the wrong character, and others that read awkwardly.
- Silver Ore no longer glows when a character approaches it.
- Fixed set effect translations that did not match the wording used elsewhere.
- Fixed awkward animations for Mabel, and modelling on Brisshell and Mabel that looked partly unnatural.
- Skill enhancement material descriptions no longer appear in another language when the client is set to English.
- Fixed typos in the quest description for “Adventure Is Out There!”.
