AION 2 daily dungeon: Odylium or Bio-Research Base?

Status on 13 Nov 2026, Global (level 45): two daily dungeons are open, the Daeva Bio-Research Base and the Odylium Repository, added by the 28 Oct update (28 October patch breakdown). The 11 Nov maintenance didn't touch Global's daily dungeons.

Global's daily dungeons as of 13 Nov

They're solo score challenges, open from level 30, with no traditional boss: you go in alone, score points against a short clock, and the reward depends on the score tier you reach. You start them from the daily dungeon menu, and they cost no Odyle Energy, only one entry from the shared counter.

• One counter (the Unknown Fissure one): 14 entries a week, back to 14 every Wednesday at the weekly reset (MetaBot, Expcarry and client data).
• Shared per server: every character on the same server uses that counter, so a run on an alt costs your main an entry.
• Shared by both dungeons: NC's 28 Oct notes say the Odylium Repository shares its entries with the Daeva Bio-Research Base.
• Extra entries: each Unknown Fissure Challenge Ticket (Bound) adds a run outside the counter (MetaBot). NC hands out 2 on days 11 and 25 of the "Atreia's Call" attendance (until 2 Dec), and 1 (2 with Premium) at six levels of the Prelude to Flight Daeva Pass; see current events.

Odylium Repository: score and Soul Crystals

Live on Global since 28 Oct 2026, the Odylium Repository pays bound Soul Crystals based on your score. That's NC's wording, with no published tier table. Soul Crystals feed pet Genus analysis (Cogni, Fera, Natura, Varian): one analysis costs 4 Soul Crystals and 1,000 Kinah, rerolls the board's stat lines and adds Insight. Those boards apply to your whole server (pets and wings guide).

Tiers unconfirmed: a single read of the Global client (Expcarry, 30 Oct) lists 250 Soul Crystals at 10,000 points, as 50 chests of 5 crystals of a random genus, plus an unstable Odylium gem worth 3,000 points. NC hasn't confirmed it, so check the reward preview before you enter.

If that read holds, a max-tier run covers about 62 analyses, and a full week of 14 runs gives 3,500 crystals: three and a half Hidden Cubes' worth (1,000 each on Global). Budget the Kinah too: 62 analyses also cost 62,000 Kinah. For comparison, until 2 Dec "Atreia's Call" gives 2,000 Soul Crystals on days 6, 13, 20 and 27, so 8,000 in all (28 Oct notes).

Korea did it differently: when this dungeon opened there on 24 Dec 2025, it paid Growth Pet Chests, and the Global client data read in early October still listed 80 of them. On Global, NC says Soul Crystals, so ignore guides that promise pet chests.

Daeva Bio-Research Base: Enhance Stones

The Daeva Bio-Research Base is a 90-second challenge: you pick one buff out of three random ones (from a pool of twelve), then clear the arena's test subjects (Game8, Expcarry). The top tier pays 10,000 Enhance Stones (client data); per Expcarry, you reach it at 10,000 points, and even a bad run pays around 3,000 stones from 100 points.

1. 1

   Pick the buff for your weak spot

   Of the twelve buffs Expcarry lists: more damage to elites if they die slowly, to normal subjects if packs drag on, +30% Attack or Combat Speed otherwise, +20% Move Speed if you lose time running around.

2. 2

   Elites first

   An elite test subject is worth about 1,000 points against 10 to 50 for a normal one (Expcarry): save your big cooldowns for them.

3. 3

   Sweep the edges

   Elites mostly spawn along the edges and in the corners; don't stand still under the turret shots.

4. 4

   End on a tier

   In the last seconds, go for the next score tier if you can reach it: the reward follows the tier, not your exact points.

For scale: 14 max-tier runs add up to 140,000 stones a week. Taking a level-86 Unique (Fire Temple, Ferocious Horn Den) from +10 to +15 costs about 129,800, failures included, and each enhancement level adds 1 item level (enhancement and costs).

Shared entries: which daily dungeon for your goal

There's no single right answer: it depends on what's holding you back this week. The splits below are our player advice, not game rules; only the 14 entries and their sharing are.

Since 28 Oct, every Hard mode Ariel Fragment (Urugugu and Vakron, then Fire Temple and Horn Den since 11 Nov) can be transmuted into 5 Enhance Stones, with no cap: if you run Hard expeditions, that's another stone source, and Odylium gets more attractive for you. The other faction's sealed dungeons, through rifts, also give stones without energy, 2,500 each but only once (all stone sources).

• Mistake to avoid: running the daily dungeon on a weak alt. It burns the same counter as your main and scores lower.
• Mistake to avoid: saving all 14 for Tuesday night and forgetting. The counter goes back to 14 on Wednesday, and unused runs give you nothing.
• Mistake to avoid: splitting entries half and half with no goal. Reaching an item level gate sooner opens a better-paying dungeon, which is often the best use of the week.

Instant Clear Tickets and per-server limits

The Wind Breeze Merchants (Shop, Special tab) sell the Instant Clear Ticket: Daily Dungeon (Bound) for 30,000 Kinah; since 28 Oct, the limit is 14 a week per server (NC's official notes). The Instant Clear Ticket: Nightmare, added the same day, sells on the same terms. Per MetaBot, you pick it on a run's completion window and it pays that run's reward again without replaying; Expcarry advises not counting on the top tier until the game shows it. Each use still spends an entry from the counter (MetaBot, Expcarry).

1. 1

   Do one real run, at your best score

   The ticket copies the reward of the run you just finished, so aim for 10,000 points by hand before spending one.

2. 2

   Finish the remaining entries with tickets

   On the completion window, pick instant clear for the number of entries you want, in the same dungeon.

3. 3

   Switch dungeons for the other reward

   To split between stones and crystals, do one manual run in the other dungeon, then use your remaining tickets.

Mind the cost: 14 tickets are 420,000 Kinah a week. They save time, not entries. Check the reward tier shown in game before you confirm; NC doesn't spell out how it's calculated.

What about Crobakhi's Secret Depository?

Crobakhi's Secret Depository (bound Kinah, 300,000 at the top tier in the client data) shows up in Korean guides and in guides translated from Korean. As of 13 Nov 2026, NC hasn't mentioned it in any Global patch notes, and Expcarry lists it as unavailable on Global. Its map is on our site because it's in the client, not because it's open, so don't plan your Kinah around it (Kinah sources on Global).

Korea: Growth Dungeons since 11 Nov

In Korea (level cap 55 since 11 Nov), the "Chapter 1, second story" update renamed daily dungeons to Growth Dungeons (성장 던전). The Ascension Trial moved in, with a new challenge: 9 attempts a week, now shared per server, up from 3. Instant clear comes with it, after a first successful run, and costs one attempt plus one ticket (Korean notes).

For the Base and Odylium, Korea's 11 Nov notes only give the new name: no change to their counter is listed, so check in game. Nothing like it has been announced for Global as of 13 Nov; the full list of version differences is in our Global vs Korea comparison.
