Revision 6

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 are enhanced with other Arcana (see below). NCsoft's official Korean guidebook (Arcana page updated August 12, 2026) now lists the sets and, for each part, which divine stat a set's card grants. The set names below are provisional English renderings of the Korean names; the divine stat names are the global client's (see Character Stats).

Equipping cards of the same set adds its set effect. The guidebook gives the full Punishment, Protection and Indomitability sets as Prelude of Punishment (징벌의 서곡), Protected Soul (수호받는 영혼) and Indomitable Tenacity (불굴의 집념), again provisional renderings. When an Arcana is used from the cube, its equip effects are rolled at set chances that depend on its grade, and most Arcana come from Transcendence rewards or from synthesis.

Sets on the Korean and Taiwanese service have arrived in batches: two with the February 25, 2026 update (Frenzy and Pure Blood), 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.

Enhancing, Extraction and Synthesis

• Enhancing: other Arcana are used as material, and using copies of the same Arcana gives bonus experience. Each attempt costs Kina, and every step raises the card's effects and the experience needed for the next. The window can auto-select identical cards and enhance to the next or the maximum step. The Punishment, Protection and Indomitability cards gain +2 to their divine stat with each enhancement (May 13, 2026).

• Growth of options: according to NCsoft's probability page, when a card with skill options grows, one of its skills goes up a level, to at most level 4; when a card with stat options grows, one of its stats rises by the listed step. Which effect grows is chosen evenly among those that can still grow. A card never rolls the same option twice.

• Extraction: spare Arcana are extracted to fill a gauge from 0% to 100% according to their grade; each full gauge gives one crystal for synthesis. Since July 15, 2026 item source information lists Arcana extraction.

• Synthesis (연성): crystals and Kina let you choose two additional effects of an Arcana directly. Since June 4, 2026 the Punishment, Protection and Indomitability cards offer four selectable effects, and their Grail and Scales are synthesized with Kina and Splendent Noble Crystals.

• Presets: the guidebook describes three Arcana presets; the October 7, 2026 update raised Arcana presets to five on the Korean service.

The guidebook's synthesis cost table (crystal names are the global client's where known):

Since May 13, 2026, three Mysterious Crystals or three Harmonious Crystals can be converted into one Noble Crystal through Material Conversion. The Punishment, Protection and Indomitability cards first dropped in Mirror of Scarlet Desire or were synthesized from Noble Crystals.

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.
