AION 2 skin combine
Combining skins costs gold by the grade you combine (Common 600, Rare 1,000, Epic 6,000, Unique 30,000) and returns a random skin: most of the time one of the same grade, and 25% of the time one grade higher for Common, 20% of the time one grade higher for Rare, 15% of the time one grade higher for Epic. The client does not say how many skins one combine takes in.

Cost and odds by grade
SkinCombineCost (gold per combine) and SkinCombine (result rows; each row's Prob is out of 100,000,000 inside its group). A combine's two result groups are 'Base', the grade you put in, and 'High', the next grade up. Expected combines = 1 ÷ the High chance, and expected gold = that × the cost: our calculation, assuming every combine is independent.
| Skins combined | Gold per combine | Same grade | Better result | Chance | Expected combines | Expected gold |
|---|---|---|---|---|---|---|
| Common | 600 | 75% | Rare | 25% | 4 | 2,400 |
| Rare | 1,000 | 80% | Epic | 20% | 5 | 5,000 |
| Epic | 6,000 | 85% | Unique | 15% | 6.7 | 40,000 |
| Unique | 30,000 | 100% | none | — | — | — |
A grade's result rows split their chance evenly: for example Common has 60 same-grade rows and 149 better-grade rows, each worth an equal share of its group. A skin's own chance is on its page. Grades with a cost but no result rows in the client are left out. All skins
