This Aion 2 enhance stone guide covers the enhancement system, which the game calls Enhancement, not enchanting. NC has not published odds, pity or costs. The numbers below come from client data read by MetaBot and Wikily, and other sites match them. Treat them as client data, not as an NC promise.
Enhancement success rates by grade
| Grade | Always succeeds | Cap |
|---|---|---|
| Common and Rare | +1 to +5 | +5 |
| Epic | +1 to +10 | +10 |
| Unique | +1 to +10 | +15 |
Observed 2026-10-14 Source Four sources list the same caps and odds: MetaBot, Wikily, AllThings and Fextralife. They may share the same client tables.
| Step | Base success |
|---|---|
| +10 to +11 | 65% |
| +11 to +12 | 50% |
| +12 to +13 | 35% |
| +13 to +14 | 25% |
| +14 to +15 | 20% |
A failure on weapons, guards, armor and normal accessories costs materials only. You do not lose a level. Observed 2026-10-14 Source
Item level never changes your odds. It changes only the price. Client-data 2026-10-14 Source
For gear grades and item levels, see the gear guide.
Pity and maximum attempts
Client-data 2026-10-14 Source
Each failure at a level adds 5% to your next attempt at that same level. A success resets the next level to its base rate. One source flagged the pity formula as not confirmed by in-game testing.
| Step | Max attempts | Expected attempts |
|---|---|---|
| +10 to +11 | 8 | 1.49 |
| +11 to +12 | 11 | 1.86 |
| +12 to +13 | 14 | 2.44 |
| +13 to +14 | 16 | 3.03 |
| +14 to +15 | 17 | 3.42 |
Client-data 2026-10-14 Source Expected attempts are MetaBot's own calculation, not a game value.
Enhancement costs in Kinah and stones
Client-data 2026-10-14 Source
| Step | Kinah | Enhance Stones |
|---|---|---|
| +0 to +1 | 12,800 | 510 |
| +10 to +11 | 360,000 | 9,310 |
| +11 to +12 | 540,000 | 10,610 |
| +12 to +13 | 860,000 | 11,960 |
| +13 to +14 | 1,340,000 | 13,360 |
| +14 to +15 | 1,860,000 | 14,820 |
Client-data 2026-10-14 Source MetaBot and AllThings agree on the +10 to +11 and +14 to +15 rows, but both likely come from the same client data.
| Item level | Fixed cost, +0 to +10 | Average to +15 | Worst case from +10 |
|---|---|---|---|
| 36 | 325,400 Kinah, 12,960 stones | about 5.31M Kinah, 67,300 stones | 26.2M Kinah |
| 70 | 632,050 Kinah, 25,180 stones | about 10.3M Kinah, 130,900 stones | 50.8M Kinah |
| 86 | 775,100 Kinah, 30,920 stones | about 12.6M Kinah, 160,800 stones | 62.3M Kinah |
| 102 | 920,400 Kinah, 36,680 stones | about 15.0M Kinah, 190,700 stones | 73.9M Kinah |
Client-data 2026-10-14 Source Average and worst case are MetaBot calculations. Extraction refunds only Enhance Stones, not Kinah, manastones or Theostones.
For scale, a +15 Ludra's Blade of Extinction adds +174 min and max Attack on a base of 446 to 604. That weapon is not obtainable until Ludra returns on Nov 4. See the gear guide and the Ludra Awakens guide.
Cheaper +15: enhance an item level 36 Unique, then transfer
Editorial 2026-10-20
A route shared on r/Aion2 on 18 October: get an item level 36 Unique piece, Soul Bind it until the stat lines suit your class, enhance it to +15, then move it onto your item level 86 piece with Transfer Stones. It works because item level changes the price of each attempt but not the odds, so the risky +11 to +15 steps cost far less on the low piece.
| Item level | Average Kinah | Average Enhance Stones |
|---|---|---|
| 36 | about 5.31M | about 67,300 |
| 86 | about 12.6M | about 160,800 |
Client-data 2026-10-14 Source Same MetaBot averages as the table above. The gap, about 7.3M Kinah and 93,500 Enhance Stones per piece, is our subtraction.
The route only pays if that 7.3M gap is larger than what you spend on the item level 36 piece plus the Transfer Stones. The post quoted about 300,000 Kinah per piece on the Market. Replies a few days later put the price at 0.8M to 2M depending on the server, so check yours first. Replies say Market access needs a membership, and they also mention item level 36 Uniques from Shugo Festival, early dungeons and field drops, and those cost nothing but time.
Limits that come from the item data
- Item level 36 Uniques stop at +15 and have no Amplified Enhancement. Do any Amplified steps on the item level 86 piece after the transfer.
- A Transfer Stone (Unique) moves the power of a Soul Bound Unique piece to another Unique piece, never to a lower grade.
- Soul Binding unlocks 3 to 5 random stats in the client data on our gear guide. The post says four, so expect your roll count to vary.
| Item | The r/Aion2 route post says | Replies and gear sites says |
|---|---|---|
| Enhancement level | Carries over, the +15 lands on the 86 piece | One gear site lists enhancement and breakthrough as carried, another lists only stat lines |
| Soul Binding stat lines | Carry over | Both gear sites list them as carried |
| Soul Binding level | Not mentioned | One player reports it reset after the transfer, and the Soul Codex spent on it was lost |
| Engraved manastones | Not mentioned | Both gear sites say they do not carry |
| Stones for a 36 to 86 transfer | 2 Transfer Stones (Unique), always succeeds | No second source found |
Amplified Enhancement past +15
Amplified Enhancement starts at 66% and falls to 20% by +5. A failure does not lower the level. The cap is up to +5, depending on the item. Observed 2026-10-14 Source
| Step | Success | Pity per fail | Cost per attempt | Max attempts |
|---|---|---|---|---|
| +1 | 66% | +5% | 600,000 Kinah, 6 Amplify Stones | 8 |
| +2 | 50% | +4% | 900,000 Kinah, 9 Amplify Stones | 14 |
| +3 | 33% | +3% | 1,400,000 Kinah, 12 Amplify Stones | 24 |
| +4 | 25% | +2% | 2,000,000 Kinah, 15 Amplify Stones | 39 |
| +5 | 20% | +1% | 3,000,000 Kinah, 20 Amplify Stones | 81 |
Client-data 2026-10-14 Source Average to +5 is about 26.2M Kinah and 196 Amplify Stones.
| Item level | Amplified cap |
|---|---|
| 36 to 51 | None |
| 54, 56, 62 | +1 |
| 70 | +3 (Splendent +1) |
| 78 | +3 |
| 86 | +5 (Splendent +3) |
| 94 and 102 | +5 |
Client-data 2026-10-14 Source
Amplify Stone Fragment (Unique) drops from Normal Expedition runs such as Urugugu Canyon, from Transcendence dungeons and from the Ludra raid. It converts through Substance Morph. Client-data 2026-10-14 Source
Amplify Stone (Unique) is a Transcendence leaderboard prize: x30 for the top 10 and x15 for ranks 11 to 50. Amplify Stone Fragment (Unique) (Bound) appears in Daeva Pass rewards. Official 2026-10-14 Source
Where to get Enhance Stones
Quests are the biggest source: 342 quests list Enhance Stone rewards. Other sources are Expedition dungeons (Krao Cave, Fire Temple), Enhance Stone Chests, achievements, attendance and the battle pass. Client-data 2026-10-14 Source
Since the 21 Oct patch, each Ariel Fragment from Expedition (Hard) can be morphed into 5 Enhance Stones under Substance Morph > Special > Consumables, with no limit. Official 2026-10-21 Source
The Substance Morph that turns Sealed Wings into Enhance Stones now has a weekly limit of 20 morphs per server (patch of 6 and 7 October). Official 2026-10-14 Source
Bulk rewards in NC notices include Twitch Drops (5,000 Enhancement Stone tiers) and the Transcendence leaderboard (35,000 for the top 10, 12,000 for ranks 11 to 50). Official 2026-10-14 Source
Sealed dungeon clears and the Daily Dungeon also pay stones. See the dungeons guide and the daily and weekly checklist. Burning Odyle is a gathering item, not an enhancement material. Client-data 2026-10-14 Source
Amulets, belts, Clash Rune, Potential and Arcana
Client-data 2026-10-14 Source
- Amulets and belts: +1 to +10 always succeed at every grade, but each attempt needs one bound enhance scroll, such as the Noble Belt scroll.
- Clash Rune: cap +10. A failure drops one level, and there is no pity. It needs a Clash Rune Enhance Scroll per attempt. One source says the drop goes "past +1", so check before you push high.
- Potential: always succeeds on Soul Bound gear. Each level costs 1 Potential Stone: Abyss (Unique) plus 100,000 Abyss Points. Levels +1 to +4 give 0.5%, 1.0%, 1.5% and 2.0% PvP Damage Boost (weapons, accessories) or PvP Damage Tolerance (armor, bracelets). All four cost 10 stones and 400,000 Abyss Points. Stones drop in Chaotic Lower Reshanta.
- Arcana: these use an EXP bar with no failure, so this guide's odds do not apply. See the Arcana guide.
Not confirmed yet
These points have no reliable Global source yet. Do not plan around them.
- NC has not published enhancement rates, pity or costs.
- Whether the +5% pity works in the live game as modeled. One source flagged it as not tested in game.
- Cost tables for item levels other than 36, 70, 86 and 102.
- What a Battle Enhance Scroll (Bound) does. The item name appears in rewards, but no mechanic was found.
- Exactly what a Transfer Stone carries over and how many stones each item level gap needs. The cheaper +15 route above rests on player reports, not on NC.
- Whether Korean Unique +11 to +15 odds match Global.
