Dungeon Basics

AION 2's PvE splits into solo, small-group and raid instances, plus open-world events and PvP. This page maps the whole instance system and what each format is for; mechanics and loot live in the dedicated guides.

Instance Formats

AION 2 groups instanced PvE into three sizes. On the Global version the small-group tier is built for 5 players and the raid tier for 10 — NC expanded both from the earlier 4/8-player KR/TW build.

TypeParty (Global)What it is
Sealed Dungeons1 (solo)Hidden dungeons scattered across the world; clear them for Wisdom Stones that raise Skill Points. In-game text: "Sealed Dungeons are hidden dungeons scattered throughout the world."
Strongholds1 (solo)Short combat challenges found around the world alongside Sealed Dungeons; part of long-term regional progression.
Nightmare1 (solo)Boss-focused seasonal challenge that unlocks at level 45. Covered in its own guide.
Ascension Trial1 (solo)A separate solo combat challenge with increasing difficulty and progression rewards.
Daily Dungeon1 (repeatable)Short repeatable content for quick daily rewards such as Kina and materials.
Expedition5The main party dungeon format: gear, unbound Kina and Arcana. Has three modes — Exploration, Conquest, Transcendence.
Transcendence5Later group content tied to Arcana progression; Arcana cards and their crafting materials come from here.
Sanctuary10The 10-player weekly raid. NOTE: removed at launch and being reworked — see the Raids section.

Party sizes above are the Global-version figures (5 / 10). The earlier KR/TW build used 4 / 8, and some older community guides still quote those numbers. NC has stated the game contains more than 200 dungeons across formats — treat the exact live count as unverified until counted in-game.

Solo Content

Solo content is where most players build their baseline gear and Skill Points outside the story.

  • Sealed Dungeons — community wikis list 162 of them (Verteron & Altgard ~60 each, recommended level 10–40; Eltnen & Morheim ~20 each at level 45; plus the advanced Ruins of the Ancient City of Ru at 45). Confirmed role: they grant Wisdom Stones for Skill Points. Counts and level bands are community-reported — unconfirmed.
  • Strongholds — open-world short fights; both Sealed Dungeons and Strongholds feed long-term regional progression.
  • Nightmare — the level-45 seasonal boss ladder; see the Nightmare guide.
  • Ascension Trial — a solo wave/boss challenge with rising difficulty and progression rewards.
  • Daily Dungeon — repeatable quick rewards (Kina, materials).

Small-Group Content (5-player)

Expedition is the standard 5-player format. Per community data its menu unlocks via an episode quest (Wind Breeze Merchants for Elyos, Daeva in a Dream for Asmodians). It has three modes:

  • Exploration — baseline group clears.
  • Conquest — harder group clears.
  • Transcendence — later content; rewards Arcana cards and their crafting materials (community-reported).

Mode names, unlock quests and Arcana drops are community-reported (fextralife wiki). Verify in your client.

Raids (10-player)

Sanctuary is AION 2's 10-player raid and sits near the top of the PvE ladder. In-game text: "Sanctuary is an extremely high-difficulty raid dungeon that requires a thorough understanding of each role."

At Global launch (2026-10-05) NCSoft temporarily removed Sanctuary for rework and said a return date would be announced by 2026-10-16. Treat its live availability as time-sensitive — check the latest patch notes before planning a raid week.

Ludra is reported as a second 10-player raid open at level 45 (single boss, three difficulty levels per community data). Its live status is also pending verification.

Sanctuary/Ludra specifics, boss lists and drop tables are community-reported and not yet verified on this site.

Open World, Casual & PvP

Beyond instanced PvE:

  • Shugo Festival — a casual mini-game collection (races, survival games) with its own rewards.
  • Dimensional Invasion — a field event in the open world, NOT a dungeon; its rewards can include Centuryroot Tokens for the Festival Shop.
  • PvP — Abyss (open-world faction PvP), Arena and Battlefield (instanced PvP), and Spacetime Rift (connects the two factions' territories). World bosses and regional events also run in the open world.
