Revision 3

Arcana is the card layer of character progression, and it is the longest track in the game. Cards drop from Transcendence dungeons, slot into a small number of fixed slots, and level individually, but the payoff is the completed set rather than any single card.

Slots

Chapter 1 added four slots at once on July 1, 2026: Key, Hourglass, Dice and Lantern. Key and Hourglass Arcana could drop immediately, while Dice and Lantern followed on August 12, 2026. Korean coverage calls these Chapter 1 parts stat Arcana. All Arcana part names on this page are provisional English translations.

Cards and Sets

Cards level to five. Set names circulating in English coverage of the Korean and Taiwanese build include Libra variants, a frenzy set, a pure-blood set, a punishment set, a guardian set and a resolve set; the renderings differ between sources, and NCsoft has not published an English set list, so this page does not fix one.

Sets on the Korean and Taiwanese service have arrived in batches: two with the February 25, 2026 update (provisionally Frenzy and Purity), three with the May 13, 2026 update (provisionally Punishment, Protection and Indomitability), and Chapter 1 added new pieces for those last three sets that can be fused for 500,000 Kina and a Pure Crystal (Bound), fixing one option.

The Dice and Lantern slots that arrived in August 2026 brought their own option pools: offensive options covering perfection, critical rating, multi-hit and impact-type accuracy, and defensive options covering regeneration, an iron-wall effect, critical resistance and impact-type resistance. Forging a single option costs Kina plus a crystal material.

Holding and Enhancing

Cards are enhanced with Training Arcana materials in Lower, Intermediate and Superior grades (provisional names). On the Korean and Taiwanese service, on February 25, 2026 the number of Training Arcana usable in one go rose from 10 to 100 and the cooldown on Arcana fusion was removed. The number of Arcana a character can hold rose to 800 on March 18, 2026 and to 1,100 on September 23, 2026. Events on the Korean service have sold Training Arcana for Kina in the Wind Breeze Merchants shop and added them to Transcendence rewards.

Why It Is the Slow Track

Three things compound. Cards only drop from one content tier, the set bonus is all-or-nothing, and once you have a set you still want a better copy of each card with the right sub-bonuses. Long-form guidance on the Korean and Taiwanese build is consistent on the same advice: start it early, because it is the track that cannot be rushed at the end.

The AI Disclosure

Arcana is also the part of AION 2 covered by NCsoft's own generative-AI disclosure. The publisher states that some in-game assets were created with the assistance of AI tools, and identifies Arcana card designs and some icons as those assets. That disclosure covers the artwork, not the system.
