AION 2 Enhancement: Rates, Costs & Pity
Enhancement mechanics from the global client: safe levels per grade, the Unique odds ladder from +11 to +15, the +5% failure bonus, and what Amplify and Potential add on top.

Quick Answer: How Does Enhancement Work?
Enhancement pushes a piece up to its grade cap. Common and Rare always succeed to +5. Epic is safe to +10. Unique is safe to +10, then rolls 65%, 50%, 35%, 25% and 20% for steps +11 through +15 — and every failure adds a +5% success bonus to the next attempt. The average Unique needs about 22 attempts on the +14 → +15 step alone.
| Step | Success Chance | Bonus Per Fail | Expected Attempts |
|---|---|---|---|
| +14 → +15 | 20% | +5% | 22.24 |
What Enhancement Costs
Attempts consume Kina and Enhance Stones, and costs scale with item level. One data point from the launch client: the +14 → +15 step on the tracked item level costs 1,860,000 Kina and 14,820 Enhance Stones per attempt at the top end. Budget by expected value, not by best case — the unlucky (90th percentile) runs cost multiples of the average.
- Enhance Stones: the core consumable — thousands per high step.
- Kina: six figures per attempt at high item levels; see the economy hub for income.
- Failure bonus: +5% success added per failure on Unique gear above the safe line — pity by another name.
Amplify: Past the +15 Cap
Many Unique items — crafted and dropped alike — can go past their normal cap with Amplify Stones. Higher item levels unlock more steps: item level 54 gear takes +1 step, item level 70 takes +3, item level 86 takes +5, with odds descending 66% → 50% → 33% → 25% → 20% and the failure bonus shrinking per step. First-step cost on those tracks is 600,000 Kina plus 6 Amplify Stones.
| Item Level | Extra Steps | Odds Per Step | First Step Cost |
|---|---|---|---|
| 54 | +1 | 66% | 600,000 Kina + 6 Amplify Stones |
| 70 | +3 | 66% → 50% → 33% | 600,000 Kina + 6 Amplify Stones |
| 86 | +5 | 66% → 50% → 33% → 25% → 20% | 600,000 Kina + 6 Amplify Stones |
Potential and Bind
Two more systems sit on top of enhancement. Potential: every Unique weapon, guard and armor piece (and nearly every accessory) has its own Potential track paid with Potential Stones and Abyss Points — every step succeeds and adds PvP damage or PvP tolerance, +2% per step at a total of 10 Potential Stones and 400,000 Abyss Points for four steps. Bind: Unique gear takes 10 Bind steps costing 2,130,000 Kina and 408 Soul Codex in total, with rebinding at 300,000 Kina and 3 reset codexes.
