Artifact Siege days & matching groups
Plan portal entry separately with the Aion 2 rift timer.
Global Artifact Siege is community-reported on Monday, Thursday and Saturday at 21:00 on the selected regional server clock. It has one configured start per region, with no Korea matching-group offsets. The Confirmed badge describes community agreement; the official Global clock timetable remains Unconfirmed.
Korea is community-listed on Wednesday and Saturday at 21:20, 21:50 or 22:20 KST for matching groups 1, 2 or 3. Choose your in-game matching group for the ring; the table retains all three groups for comparison.
Taiwan's official September 30 update lists Wednesday and Saturday at 21:30 GMT+8, with follow-up bosses at 21:45. Taiwan uses a single start and does not use the Korean group selector. NC Taiwan update →
Artifact Siege, Kaira & Nahma are separate timers
Artifact Siege is the artifact battle; Watcher Kaira is a recurring field boss, Executor Kaira is a follow-up siege boss, and Nahma has its own Friday/Sunday timetable. Global follow-up Siege Bosses are community-listed at 21:30 on Monday, Thursday and Saturday.
Global Watcher Kaira provisionally starts at 01:00 every three hours; Nahma provisionally starts Friday and Sunday at 21:00. Their source conflicts remain Unconfirmed. Use the world boss and field boss timer for those countdowns rather than interpreting this siege ring as a boss spawn report.
For other activities, use the AION 2 rift timer, Dimensional Invasion time and countdown, Shugo Festival timer and Global daily and weekly reset time pages.
Artifact Siege timing rules
Events follow the selected service's server clock. Global uses regional clocks: NA East (America/New_York), NA West (America/Los_Angeles), EU (Europe/Berlin), South America (America/Sao_Paulo), Asia (Asia/Tokyo). Global resets are anchored independently at 07:00 UTC. Static Global tables default to Asia; select your game region for live conversions. Sources still differ on rifts; in-game schedules take priority. Official Global clock confirmation: not published in the sources reviewed. The listed recurring times are community references, not estimates of an unpublished official value.

Artifact Siege FAQ
01What time is Artifact Siege in AION 2 Global?
The community-reported Global timetable lists Monday, Thursday and Saturday at 21:00 on the selected regional server clock. NCSOFT has not published a verified Global clock timetable in the sources reviewed. Confirmed means community references agree on the rule; it does not mean official confirmation or a live siege report.
02What are Korea's Artifact Siege matching-group times?
The current Korea profile lists Wednesday and Saturday at 21:20 for Group 1, 21:50 for Group 2 and 22:20 for Group 3, on the Korean UTC+9 clock. These are community-reported patch references. Choose the matching group shown in your game; all three groups remain visible in the comparison table.
03What time is Artifact Siege in Taiwan?
NC Taiwan's September 30 update lists Wednesday and Saturday at 21:30, with follow-up bosses at 21:45. Taiwan uses UTC+8 and one service-wide start, rather than Korea's three matching groups. The countdown and UTC conversion use that separate Taiwan rule.
04Is Artifact Siege the same as Watcher Kaira?
No. Artifact Siege is a scheduled artifact battle. Watcher Kaira is a separate field boss with a recurring cycle; Global currently uses a provisional three-hour profile from 01:00. Executor Kaira is a different scheduled siege boss. Use the world boss timer to compare their names, times and confirmation status.
05Is Nahma part of Artifact Siege?
Nahma has a separate Friday/Sunday schedule: Global provisionally lists 21:00; Korea lists 22:00, 22:30 or 23:00 by matching group; Taiwan's official update lists 22:00. Do not use the Artifact Siege countdown as Nahma's spawn countdown.
06Does this countdown confirm that the siege is live?
No. It calculates scheduled starts and the community-listed 30-minute activity window. During that window the ring counts toward its scheduled end. Maintenance and in-game notices take priority; an official maintenance completion notice does not verify the spawn of an individual siege.
Data & Sources
Rechecked 2026-10-09: Global events use regional clocks and rifts start at 02:00, then every 3 hours. Aion 2 Maps reports NA West in-game and regional stream observations; Aion2 Meta reports an EU clock check; Shugo agrees. Global resets stay at 07:00 UTC. Hub and Corpus still differ on rift timing. Confirmed means community agreement, not official confirmation or live telemetry. Actual weekly reset completion has not been independently observed by this site. Taiwan siege times are separately checked against NC’s September 30 update.
