# Refinement System
## Refinement System
The Refinement System allows players to upgrade equipment using ores and refined materials at the Hollgrehenn NPC. Normal ores like Phracon, Emveretarcon, Oridecon, and Elunium are used for basic refinements with associated Zeny costs.
### Items Used for Refinement
Normal ores are required for different equipment levels, with Zeny costs scaling by level.
| Type | Required Ore | Zeny Cost |
| ----------- | ------------ | ----------- |
| Weapon Lv.1 | Phracon | 5,000 Zeny |
| Weapon Lv.2 | Emveretarcon | 10,000 Zeny |
| Weapon Lv.3 | Oridecon | 15,000 Zeny |
| Weapon Lv.4 | Oridecon | 20,000 Zeny |
| Armor | Elunium | 20,000 Zeny |
### Enriched Ores
Enriched ores provide higher success rates for specific equipment types.
| Enriched Ore | Equipment Type |
| ----------------- | -------------- |
| Enriched Elunium | Armors |
| Enriched Oridecon | Weapons |
### Refinement Usables
Protect equipment during refinement failures with special scrolls.
* **Scroll of Protection**: Downgrades equipment instead of destroying it on failure; works only with Hollgrehenn NPC and consumes one per attempt.
### Success Chances:
Success rates decrease at higher levels, varying by weapon level and armor.
