AION 2 Patch Notes — Launch Day Build and Hotfixes

AION 2 patch notes for the global service start with one entry. The game launched on October 5, 2026 at 13:00 UTC, and the build that opened came out of a single eight-hour maintenance window carrying a single published set of changes. This page was last checked against NCSOFT’s own feeds on October 6, 2026 at 02:30 UTC. Nothing has been published since the October 5 launch posts, so the launch note is still the complete shipped change list — and the ledger below is the place every later hotfix gets appended, one row per notice, with the check time at the top moved forward each pass.

What shipped in the AION 2 launch build

One notice, published October 4 at 11:43 UTC on the Steam news feed (AppID 3393110), titled “Scheduled Maintenance Sun Oct 4 / Mon Oct 5”, applied during a window running from 05:00 to 13:00 UTC on October 5. That window is the same eight hours that ended Advance Access and opened the free global launch, which is why the patch note and the release date and launch time guide share a clock.

Two of the three issues on NC’s Advance Access known-issues notice of October 3 — the mislabelled title and the level 45 Duty lockout — appear here as fixes. The third, a “Please Try Again Later” message that can block chat, is not listed in the launch note, so it should be treated as still open rather than quietly assumed fixed.

Which feed each AION 2 patch note was published to

Notices get split across channels, and the split is the reason some changes are easy to miss.

The third row is the trap. The playtest feed carries a genuine “AION 2 Hot Fix Update” from September 18 at 03:57 UTC that raised the quest interaction radius, blocked appearance change tickets below level 10, and fixed chat reporting and crashes. That is a test-build change. None of it is part of the October 5 retail build, and quoting it as a launch hot fix is a category error. The server status and maintenance page documents that same channel split from before launch.

The hotfix ledger, October 5 to now

Empty below the header because NC has not published a post-launch patch note yet. The last first-party build change on record remains the October 1 no-downtime fix, which belongs to Advance Access rather than to launch: it corrected Advance Access entitlement not being recognised at login and in-game purchase failures, and it applied on the next client restart with no downtime.

The gift posts are the most common source of confusion on launch day, because they arrive faster than fixes and get filed as patches by aggregators. A voucher or a giveaway is compensation, not a code change.

Ludra came out with the launch build, and it is not in the patch note

A separate official site notice, “Update on Sanctuary Raid”, published October 5 at 12:40 UTC, removed Sanctuary Raid: Ludra from the launch build. The board displays UTC — cross-checking against NC’s “Will Launch On Time” post, which the Steam feed time-stamps at 12:48 UTC, puts the two channels within two minutes of each other.

The stated reason is that Ludra was cleared during Early Access at a lower progression level than intended, and NC decided Global players should get the discovery again. Ludra-specific gear earned during Early Access is temporarily removed too, with the items granted back and upgrade materials reimbursed on return; the Hall of Fame resets, a new First Clear event runs, and every player who cleared Ludra in the Europe region during Early Access receives a commemorative title. NC will publish the return date by October 16. If you were levelling toward the gear progression path, this is the one launch-day change that can make a target disappear, and it was never listed in the maintenance note.

What players are hitting that no patch note mentions

These are launch-day reports with no first-party confirmation. They belong to the launch errors and fixes page for triage, and they are listed here so they are not mistaken for shipped fixes.

Read the first row against the server population page: a world that closes creation is full, not broken, and existing characters still log in. NC’s own queue policy — priority placement for accounts in good standing — is why a launch-day login attempt can take hours without being an error at all.

The September 16 Korean balance patch is not a global patch

One line needs to stay quarantined. As of September 30, 2026, Space4Games reported a Korean balance patch on September 16 that added elemental damage to Ranger attacks, and whether it carries into the global build is unconfirmed — a note recorded on the Ranger guide as a thing to check at launch rather than a fact.

It remains a comparison row, not a launch change. Nothing in the October 4 global patch note mentions class balance at all, so on the evidence published so far, no balance change has shipped on Global. The Korea and Taiwan service is a separate build with its own cadence, and the global versus KR/TW differences page covers what else does not travel between the two.

How to check the AION 2 patch notes yourself

Four places, in the order worth checking:

1. Steam news, AppID 3393110 — where every launch and maintenance note has landed. Bookmark store.steampowered.com/news/app/3393110.
2. The official site notice board at aion2.plaync.com — where content decisions that are not patches land, such as the Ludra removal.
3. The in-game notice screen — the client mirrors the same notices, which is the version to trust when the two disagree on wording.
4. The official Discord — for acknowledgement before a written note exists, and for bug-report intake. The Discord and community channels page lists where players are actually watching.

How this page is maintained: by hand, against NCSOFT’s own feeds, not from a monitor. Each pass records the check time at the top and appends new rows. Testing-server notices are excluded by construction, and any claim that cannot be traced to a numbered NCSOFT notice is labelled unconfirmed rather than promoted.

Sources and verification

• Steam news API, AppID 3393110, read October 6, 2026 — titles and UTC timestamps of every launch-day post; full text of “Scheduled Maintenance Sun Oct 4 / Mon Oct 5” (Oct 4, 11:43 UTC), “Advanced Access Known Issues” (Oct 3, 07:33 UTC) and “Update on account issues and in-game fixes” (Oct 1, 11:32 UTC)
• Steam news API, AppID 4972320, same day — 8 items, newest October 19-era closing post; the September 18, 03:57 UTC hot fix belongs to this feed only
• Official site notice board, aion2.plaync.com — “Update on Sanctuary Raid” (Oct 5, 12:40 UTC) and “AION 2 Will Launch On Time” (Oct 5, 12:50 UTC), used together to establish that board timestamps are UTC
• Player-side error-code and restriction reports, third-party trackers — used only for the unconfirmed table, attributed there and not promoted

Evidence level: Official for every row in the launch build table and the hotfix ledger, all read from NCSOFT’s own announcement feeds rather than from coverage. Unconfirmed for the community report table and for every error code, which is precisely why those rows are labelled rather than resolved. The September 16 Korean balance change is single-sourced and carried as a comparison row only.
