World Bosses FAQ

When does Watcher Kaira spawn?

Our provisional Global schedule starts at 01:00 and repeats every three hours. Shugo and Questlog disagree on the starting hour, so Watcher Kaira remains Unconfirmed.

What time is Artifact Siege in AION 2?

Global lists Monday, Thursday and Saturday at 21:00 server time. Korea and Taiwan use Wednesday and Saturday at 21:20, 21:50 or 22:20 for matching groups 1, 2 and 3.

When does Guardian General Nahma spawn?

The provisional Global schedule is Friday and Sunday at 21:00; Questlog currently differs. Korea and Taiwan list 22:00, 22:30 or 23:00 on those days, depending on matching group.

Do Korea and Taiwan have different siege times?

Their listed clock times match, but Korea uses GMT+9 and Taiwan GMT+8. Identical wall-clock entries therefore happen one hour apart in UTC.

What are siege matching groups?

The game staggers Abyss activities across three matching groups. Choose the group shown in your game. Your selection is saved locally and applied to all grouped activities.

Are these live server spawn reports?

No. These are source-based schedule predictions. Confirmed identifies agreement between independent references; clock conflicts, maintenance and in-game announcements can still change actual spawns.

Data & Sources

Global clock check: Shugo and Aion2 Meta publish regional clocks, while AION2 Hub lists GMT+9. This timer keeps the unified GMT+9 profile pending launch-day verification. Confirmed labels mean agreement on the listed schedule, not a verified live Global clock.

Sources compared: 2026-10-05. This is a reference review, not an in-game observation. In-game notices take priority.
