# Item Upgrade

### 🔨 Upgrading Items in *Eternal Odyssey*

Upgrading items is a crucial way to enhance your character's power. This system lets you improve an item’s **level**, which increases its attributes and overall effectiveness. However, it’s important to understand the limitations and costs involved.

***

### ⚠️ Upgrade Restrictions

* **You can only upgrade an item’s level.**
* **You CANNOT upgrade the item's Tier or Rarity.**
* Each item has a **level cap based on its rarity** — higher rarity items can be leveled up more times than lower rarity ones.

## Upgrade Success Rates

The success rates for upgrading items vary based on the item's rarity and level. The table below shows the success rates for upgrading items at different levels:
