Stigma System
October 2, 2026 at 03:31 AM
Added Stigma Shard conversion recipes, reset cost history and the shared skill slot change
Stigma is the layer of your skill bar that you invest in rather than simply unlock. A Stigma slot holds a skill that can be levelled well past where ordinary skills stop, and because slots are limited, what you put in them is the shape of your build.
Element | Detail |
|---|---|
Slots at launch | Four |
Slot expansion | Raised to five on March 25, 2026 (when Mastery and Stigma skills also started sharing one set of slots, except the basic attack), and to six on the Korean and Taiwanese build with the Chapter 1 update on July 1, 2026, with the sixth unlocking at level 50 |
What goes in them | Class skills, chosen per build rather than fixed |
Stigma sits alongside the rest of the loadout: twelve active skills and ten passives, allocated with Mastery Points, while Stigma levels consume Shards.
Range | Cost |
|---|---|
Up to level 20 | Ordinary Stigma progression |
Level 20 to 25 | Advanced Stigma Shards |
The cap was 20 until the Chapter 1 update raised it to 25.
Advanced Stigma Shards come from two places. You get one every time your character levels from 45 onward, and you get one the first time a Stigma skill reaches level 20. The second source is recoverable: resetting that skill returns the shard.
Up to level 20, Stigma levels use ordinary Stigma Shards. Expedition and Transcendence Odyle Energy Cubes and Abyss Commands drop Unstable Stigma Shards, which become Stigma Shards through material conversion. The recipes on the Korean and Taiwanese service since December 24, 2025:
Recipe | Materials | Chance |
|---|---|---|
Standard | 12 Unstable Stigma Shards and 250,000 Kina (was 300,000) | 25% (was 20%) |
Guaranteed | 48 Unstable Stigma Shards and 1,000,000 Kina | 100% |
The Kina cost of the conversion was lowered again on February 25, 2026, and since July 1, 2026 the conversion requires level 45. The Stigma Shard Boost-Up event from March 25, 2026 doubled Unstable Stigma Shards in Expedition and Transcendence cubes. Korean coverage of the Chapter 1 preview also reported that reaching level 25 on a Stigma skill opens an additional specialization for it.
Stigma resets cost Kina (10,000 per point from January 28, 2026, with a free week from April 22 to April 29, 2026) until the Chapter 1 update made them free on July 1, 2026. That change matters more than it sounds, because it turns Stigma from a commitment into a loadout: swapping between a dungeon build and a PvP build no longer has a price attached.
Stigma is a name carried over from the original AION, where it worked differently. Everything above describes AION 2's version. Do not import the first game's stigma stones, slot rules or skill lists; they are not this system.
Classes for what goes in the slots. Combat and Skill Chains for how skills chain. Daeva System and Daevanion Board for the parallel talent layer. Gear and Progression for equipment.
