# ✨ Refining
Refining enhances equipment stats by combining two items. Any equippable item can be refined up to level 10.
## Basics
- Combine two items to increase their stats
- Requires gold for each refinement
- Use [[Charms]] to increase success chance
- The resulting stats depend on both input items' stats
- Success chance must account for number of items being refined
> 💡 Since results depend on input stats, using two items of the same level typically gives the best outcome. The community calls this "perfect refinement".
## Costs & Success Rates 💰
| Level | Gold Cost | Base Success % |
|-------|-----------|----------------|
| 2 | 250 | 100% |
| 3 | 500 | 60% |
| 4 | 750 | 30% |
| 5 | 1,000 | 20% |
| 6 | 1,250 | 10% |
| 7 | 1,500 | 5% |
| 8 | 1,750 | 3% |
| 9 | 2,000 | 1% |
| 10 | 3,000 | 0.5% |
## Multi-Refining
When refining multiple items simultaneously:
- Required success chance multiplies by number of items
- Example: Refining two Level 4 items needs 60% (30% × 2)
- Maximum items determined by available inventory
- Total gold cost multiplies by number of items
- More efficient charm usage due to precise success rates
## Stat Increases 📈
Stats increase differently based on type and level difference:
### Combat Stats (25% base) ⚔️
- Attack, Defense, HP, Speed, Luck, Mana
- Elemental Resistance
### Critical Stats (16.7% base) 🎯
- Critical Chance
- Critical Damage
### Resource Stats (12.5% base) ⛏️
- Mining Power
- Fishing Power
### Gathering Stats (6.25% base) 🍓
- Berry Encounter Chance
- Mushroom Encounter Chance
## Charm System 🍀
![[Charms]]
Multiple charms stack multiplicatively. When refining multiple items, total required success chance increases but charm effectiveness is divided by the number of items.
## Resource Requirements for Perfect Items 📊
| Level | Items | Gold |
|-------|--------|----------|
| 2 | 2 | 250 |
| 3 | 4 | 1,000 |
| 4 | 8 | 2,750 |
| 5 | 16 | 6,500 |
| 6 | 32 | 14,250 |
| 7 | 64 | 30,000 |
| 8 | 128 | 61,750 |
| 9 | 256 | 125,500 |
| 10 | 512 | 254,000 |
## Strategy Tips 💭
- **Perfect Refinement**: Always use same-level items for equipment you plan to keep
- Multi-refining saves charm usage through more precise success rates
- Early-game items with very low stats can sometimes skip perfect refinement due to the minimum +2 increase
- Consider saving materials for perfect refinement of endgame gear
