Enhancement success rates by grade
Success rates depend only on the grade; item level changes the cost, not the odds. Steps up to the safe level always succeed.

| Common | +5 | +5 | Always succeeds | — |
| Rare | +5 | +5 | Always succeeds | — |

Sync chances
Bind costs come straight from the client. The two Sync chances are separate client tables (item-level gap and grade pair); the data does not show how the game combines them.

Each cell is Kina plus Soul Codex (Bound); Rebind uses Soul Codex: Reset (Bound). Gear that uses each table: Common 204, Rare 519, Epic 1,246, Unique 1,118, and Heroic 2.
Sync chances
The client's item-level table is exactly linear: the chance equals the item-level gap in percent, from 0% with no gap up to 100%. The grade table gives the chance for each pair of gear grade and material grade.
| Gear grade | Common | Rare | Epic | Unique | Heroic | Mythic |
|---|---|---|---|---|---|---|
| Common | 100% | 100% | 100% | 100% | 100% | 100% |
| Rare | 10% | 100% | 100% | 100% | 100% | 100% |
| Epic | 0% | 2% | 10% | 100% | 100% | 100% |
| Unique | 0% | 0% | 0% | 100% | 100% | 100% |
| Heroic | 0% | 0% | 0% | 30% | 100% | 100% |
Reaching a 100% binding rate will unlock an additional Manastone slot. Soul Fuse becomes available upon hitting 100% Soul Binding rate
Gear Transfer (Transfer Stones)
Gear Transfer moves enhancement and Soul Binding onto another Unique item of the same slot. Normal Transfer and Superior Transfer succeed 100% of the time in the client data, cost no Kina and only use Transfer Stone (Unique) (Bound).

Soul Fuse (Philosopher's Stone)
Soul Fuse adds an extra effect slot to Soul Bound gear. 680 Unique items can use it: 2× Philosopher's Stone: Revelation (Bound) and 1,000,000 Kina per attempt, 100% success.
| Grade | Philosopher's Stone | Kina | Chance | Gear |
|---|---|---|---|---|

Adds a Soul Fuse slot and automatically binds an effect. Soul Fuse effects cannot be transferred.
Every weapon, armor piece and accessory in AION 2 can be enhanced with Kina and Enhance Stones. The success rate is fixed by grade: Unique gear is guaranteed up to +10, then drops to 65% and lower, and every failure adds +5% to the next attempt until you succeed, so bad luck is capped. Taking item level 102 Unique gear from +0 to +15 costs about 14,986,721 Kina on average. Many Unique items, crafted or dropped, can then go further with Amplified Enhancement, and every Unique weapon, guard and armor piece also has its own Potential track. This calculator reads all 75 enhancement curves straight from the global client.

AION 2 enhancement FAQ
What is the enhancement success rate in AION 2?
Unique gear always succeeds up to +10. After that the rates are 65% → 50% → 35% → 25% → 20%, and each failure adds +5% to the next try. Lower grades are fully guaranteed up to their cap.
Can gear break or lose enhancement levels in AION 2?
Not for weapons, armor or regular accessories: in the global client data a failed attempt only costs the materials. The one exception is the PvE rune, which falls back one level when an attempt fails.
How much Kina does it cost to enhance to +15?
For item level 102 Unique gear the average from +0 to +15 is about 14,986,721 Kina plus Enhance Stones. Lower item levels cost much less; the cost table above lists every item level, and the calculator shows the lucky and unlucky range.
What is Amplified Enhancement in AION 2?
It lets Unique gear with an Amplified track, crafted and dropped items alike, go past +15: up to 5 extra levels on the highest item level, using Amplify Stones and Kina. Each extra level has its own success chance and a smaller bonus per failure.
How much does Soul Binding cost in AION 2?
Heroic gear has 10 Bind steps that cost 8,435,000 Kina and 2,168× Soul Codex (Bound) in total. Rebinding costs 450,000 Kina and 5× Soul Codex: Reset (Bound). Reaching a 100% binding rate will unlock an additional Manastone slot.
How does Gear Transfer work in AION 2?
