AION 2 dungeons guide: progression order and key bosses

Dungeon families at a glance

Every expedition, Transcendence or Sanctuary reward cube consumes Odyle Energy: 40 in general, 20 or 30 for the first three Explorations. Weekly counters reset on Wednesday.

The recommended progression order

1. 1

   Levels 10 to 35: sealed dungeons and Exploration

   Clear sealed dungeons along your route, then Krao Cave (level 20), Urugugu Canyon (28) and Fire Temple (35) on Exploration. The 20 or 30 Odyle cubes are cheap, and their loot carries you to 45.

2. 2

   Level 30: the dailies

   Daeva Bio-Research Base first (Enhance Stones, up to 10,000 per run), then the Odylium Repository (pet chests) and Crobakhi's Secret Depository (Kinah).

3. 3

   Level 45: Krao and Draupnir on Conquest

   Your first Uniques (item level 54). Both accept a solo player. Start the easy Ascension Trial alongside.

4. 4

   Item level 1,400 to 1,600: Urugugu and Vakron

   Item level 70 set, with at least two players. Save your Odyle Energy for the Conquest whose pieces you really want.

5. 5

   Item level ≈ 1,600: Transcendence

   Deus Research Base and Shattered Arkanis drop the Arcana, which weigh more than enhancement.

6. 6

   Item level 2,100 to 2,200: Fire Temple and Horn Den on Conquest

   Item level 86 set: the gear you will enhance for a long time.

7. 7

   Item level ≈ 2,800: Ludra

   Item level 102 weapons and guard, the top of Season 1.

The six expeditions: bosses and loot

Each tier pairs two dungeons: one gives the weapon and jewelry, the other the armor and guard. Run both. At Krao, Urugugu and Fire Temple, Exploration drops one notch below Conquest; elsewhere both modes share the same item table according to client data. The pity system lets you pick a piece after 14, 21 or 28 cube openings, depending on the dungeon.

The item level thresholds come from the Global client as read by MetaBot and Expcarry. Game8 lists others, higher and close to the Korean values (Conquests at 1,000, 1,600 and 2,200). The dungeon's entry screen settles it.

Key expedition boss mechanics

• Berk (Krao Cave): below 60% HP, Wave of Fury forces you behind the rocks. At 50%, Extinction for Eternity can only be interrupted by filling the stagger gauge. Stay behind him.
• Bakarma (Draupnir): at 50% HP, the whole group is sent to the arena's edges and very heavy waves arrive. Jump them, reach the boss and use high-stagger skills; on Conquest this pattern often wipes the group.
• Raur and Auldor (Urugugu Canyon): when Raur raises his shield around 2/3 then 1/3 HP, stop attacking and back off to the edge, since he reflects damage. Auldor is a DPS check: the yellow gauge in the middle of his bar is an enrage timer, so use attack consumables before the pull. Around 70% and 30%, one player is marked and the whole group must stack inside their circle to share the hit.
• Tiere, Thamon and Vakron (Sky Island): outside boss rooms the Surveillance debuff stacks and downs you at 3 stacks; walk near mist spirit stones to reset it. Thamon absorbs physical or magical damage depending on his aura, so bring a mixed group. Vakron has two group-wiping patterns: Erupting Thorns and Stone Prison.
• Kromede's Desire (Fire Temple): around 70% and 35% HP, fire walls advance, so move through the gaps; at 35%, clones shoot from the sides. The DPS timer is tight.
• Kwapo, Duanka and Nuakum (Horn Den): Kwapo asks you to touch electric orbs before a timer ends. At Duanka, a single DPS who took the altar orb can destroy the four clones. Nuakum applies a debuff that leaves a damage zone under your feet and chains frontal claws.

Transcendence and raid: what wipes a group

• Deus Research Base: Nazmun's triple frontal laser is the number one killer of melee players. At Atiel, falling off the arena is final, and around 20 to 30% HP you must empty the stagger gauge in time. Activate the Kibelisks along the route: they count for the ranking.
• Shattered Arkanis: Talisra is the one-mistake boss, with white and black orbs then a colored shield sequence. Decide who takes which color before the pull. At Siliator, make the two saws chasing the targeted players cross each other.
• Abyssal Forge: Ludra (10 players): build your two groups of 5 before entering. The reactor falls, then one group fights Rahu (a time bomb you pass around: three black holes means a wipe) while the other activates Abyss stones. Ketu swaps roles, then everyone chains into Ludra, with the Ludra Trial (a checkerboard at 50% and 25%) and the Thunder Zone, where you must step into a circle of your color at the right moment.

These mechanics come from Korean guides written for groups of 4 or 8, before the move to 5 and 10. Damage values and some details may have changed on Global: adapt roles to your group.

Loot, Odyle Energy and pity

• Odyle Energy regenerates 15 every 3 hours on all your characters, which is 120 per day: three Conquest cubes. The cap is reportedly 560, or 840 with the membership (MetaBot).
• The membership lets you inject energy twice into an expedition, Transcendence or Sanctuary cube for one more selection (NC's official notice).
• Leaving without opening the cube still spends a weekly counter, and 10 unopened cubes per week per server block entry to Conquest and Transcendence.
• The Unique drop rate is low (7.5% at Horn Den on the Global test client, according to AION2Hub), but pity makes the number of runs your real calculation.

Global or Korea: what differs

• Group sizes: identical today, 5 players in expeditions and Transcendence, 10 in Sanctuary. Korea moved from 4 to 5 and from 8 to 10 on 1 July 2026.
• Thresholds and loot: lower on Global, for example Krao Conquest at 700 versus 1,000 in Korea, and 7.5% Unique versus 10% at Horn Den (AION2Hub, September test client).
• Content still absent on Global: Dying Dramata's Nest, Cradle of Nihility, Hall of Illusion, Azure Breath Island, Citadel of the Fallen Daeva, Submerged Life Temple and the later sanctuaries. They are in the client data, but NC has announced neither their opening nor a date.
• Transcendence: only Deus Research Base and Shattered Arkanis are named by NC for its launch ranking.

• Dungeons and bossesEach dungeon with its loot and rates.
• BossesBoss pages, phase by phase.
• Group compositionRoles and classes for a group of 5.
• Global enhancementWhat to upgrade with each tier's loot.
