Sanctuary is the ten-player raid tier and the ceiling of AION 2's instanced PvE. Where Expedition is the tier a group runs weekly, Sanctuary is the tier a group organises around. It carries the highest item level requirements in the game and the largest Odyle Energy cost per entry.
How Sanctuaries Work
Element | Detail |
|---|---|
Party size | Ten players. Sanctuary ran with eight before the Chapter 1 update on July 1, 2026 raised it. |
Entry cost | 80 Odyle Energy, doubled from 40 in the same update |
Final boss clears | One per week. That was cut from two, with rewards doubled to compensate, and the accumulated guaranteed-reward counters were halved at the same time. |
Mid-boss rewards | Removed from the older Sanctuaries; the payout now comes from the Odyle Energy that appears when the last boss dies. |
Difficulty | The newest Sanctuary ships in three difficulties rather than two |
The global build's first Sanctuary raid is a ten-player fight, which matches the storefront's description of ten-player group dungeons as one of the three formats across the 200-plus dungeon roster.
The Sanctuary Roster on the Live Build
Sanctuary | Notes |
|---|---|
Chalice of Muspel | Set in an ancient temple submerged beneath lava deep inside the Muspel volcano. Added May 2026 at an item level 4,500 gate, with a Normal difficulty added in June and the original renamed Hard. |
심연의 재련: 루드라 | Live-build Sanctuary. No English name has been published. |
침식의 정화소 | Live-build Sanctuary. No English name has been published. |
비탄의 설원 | Added September 9, 2026 as the Chapter 1 finale and the current live-build ceiling, in Easy, Normal and Hard. Its boss is the Storm Legion commander Deltras. Entry starts at item level 5,800 and rises with difficulty. |
Deltras is a story boss as well as a mechanical one: once a hero and guardian of Elysium, executed in Asmodae, now a thought-form trapped in a mental space of his own making, repeating the same betrayal. Both factions have a reason to put him down, and the encounter has the players work with his daughter Elpistera to stop his body.
Hall of Fame
The September 9, 2026 patch added a Hall of Fame that records the first, second and third kills of a Sanctuary's final boss across every server, for the hardest difficulty only.
Recorded | Detail |
|---|---|
Identity | Character name, server, legion, class |
Performance | Highest combat power and highest item level reached during the run, force position, clear time |
Timing | The date the record was set |
Characters with no contribution are not recorded, and a record does not change if the character, server or legion is renamed afterwards. It is reachable from a tab on the Sanctuary entry screen.
Commendations
The same patch added a commendation system that runs in Expedition, Transcendence, Trials and Sanctuary. After the last boss dies, eligible players can hand one commendation to one other player, choosing a reason from a fixed set: outstanding skill, reliable guardian, dedicated support, excellent leadership, or kind mentor. It is one per clear, it runs on a timer, and the totals accumulate on the character sheet.
Global Availability
Everything above except the party size and the ten-player format is Korean and Taiwanese live-build state. NCsoft has not published which Sanctuaries are present in the global build at launch on October 5, 2026.
