Expedition Dungeons
October 2, 2026 at 04:04 AM
Updated dungeon names to the official English forms (Hall of Illusion, Azure Breath Island, Expedition Ordeal)
Expedition is the five-player instanced tier, the middle rung of AION 2's dungeon ladder between solo content and the ten-player Sanctuary raids. It is where most group play happens: the roster is the widest of any tier, the gear it pays out feeds the rest of progression, and it is the tier the global marketing puts in front of new players.
Element | Detail |
|---|---|
Party size | Five players. Expedition ran with parties of four until the Chapter 1 update on July 1, 2026 raised it. |
Modes | Exploration, and Conquest split into Normal and Hard |
Entry cost | Odyle Energy rather than a ticket. Entry tickets and charge tickets were removed in the Chapter 1 update, and existing ones were deleted from inventories and storage. |
Gating | Character level plus a minimum item level , set per dungeon and per mode |
Pets | Pets can be ridden inside dungeons, except during boss fights and in spaces built around special play |
Weekly limits | The weekly reward and final boss kill limits were removed on July 1, 2026. Leaving a cleared run without taking the reward uses up a weekly allowance shared by the characters on a server, and entry is blocked when it reaches zero. |
On the Korean and Taiwanese build the Citadel of the Fallen Daeva shows the shape of the cost curve: Exploration and Conquest Normal each ask 40 Odyle Energy at item level 3,800, while Conquest Hard asks 60 at item level 4,500 and pays out more in return.
NCsoft's own global material puts four Expeditions in front of players as the tier's showcase, each described as a dungeon for up to five players.
Expedition | Setting | Boss |
|---|---|---|
Krao Cave | A cave once used as a laboratory by the Lepharists. Treasure-hunting tomb raiders reopened it and woke its dormant security systems along with what was sealed inside. | Berk, a combat-type experimental subject left over from a forgotten war |
Urugugu Canyon | A divine realm hidden deep in Tolbas Forest, guarded for ages by the Aullaeu tribe. | Auldor, a legendary divine bird that soars the canyon sky |
Fire Temple | A temple built by the gods deep in caves where lava pulses, past traps and Watchers, ending at a mirror with a will of its own. | The shadow of the desire that consumed Kromede |
Draupnir | An unknown Abyss that swallowed the Draupnir Caves. | Transcendent Bakarma, once a Dragon High Commander, remade by a power he met inside the Abyss |
The Korean and Taiwanese live build carries a wider roster on top of those four, added over successive patches.

Where NCsoft has published an English name, the table uses it: Vakron Sky Island, Dying Dramata's Nest, Cradle of Nihility, Hall of Illusion, Citadel of the Fallen Daeva and Consumed Deus Research Base all come from NCsoft announcements. Ferocious Horn Den, Azure Breath Island and most boss names are the game client's English data.
The Expedition Ordeal (Korean 시련) is a custom-difficulty mode on one Expedition at a time. You set the conditions yourself and take a harder fight for better rewards. The first Ordeal ran on Vakron Sky Island from July 15, 2026, and Fire Temple replaced it on September 23, 2026.
Option | Effect |
|---|---|
Time limit | Caps how long you have |
Revival limit | Caps how many times the party can come back |
Boss buff | Strengthens the boss |
Dungeon debuff | Weakens the party |
The mode runs through the Expedition interface and is aimed at players who have already cleared the standard tiers.
Expedition drops feed the standard gear chain and the Draconic crafting materials, delivered through Odyle Energy Cubes at the end of a run. The September 9, 2026 patch on the Korean and Taiwanese build redistributed those materials: the older Expeditions now drop bound materials only, while the newer four drop the full set in both bound and tradeable form.
Kina earned in several Expeditions was also converted to bound Kina, which is NCsoft tightening the flow of tradeable currency out of instanced content rather than a change to the dungeons themselves.
