### Overview

In Legend of Arcadia, NFT heroes can be strengthened through NFT Hero Upgrade. By consuming idle NFT Heroes of the same rarity from the inventory, players can enhance the target NFT **Hero Attribute**. There are two types of NFT Hero Upgrades:

### Upgrade

By consuming other idle NFT heroes with the same rarity from the inventory, players can enhance their ***Hero Attribute*** with a randomly generated value within the [***Boost Range***](#boost-range)***.***

### Power Upgrade

| Rarity | Cost for Power Upgrade |
| ------ | ---------------------- |
| N      | 16.67 ARCA             |
| R      | 33.33 ARCA             |
| SR     | 125 ARCA               |
| SSR    | 250 ARCA               |

Players can enhance their NFT ***Hero Attribute*** to the maximum value from the [***Boost Range***](#boost-range). This requires a cost of $ARCA when consuming idle NFT Heroes with the same rarity from their inventory.

It is important to note that the rarities of the NFT Heroes consumed as materials must match the rarity of the targeted NFT Hero.

### **Hero Data -**  Upper Cap of Each Hero A**ttribute**&#x20;

Additionally, each Hero Attribute has an upper cap. When an NFT hero is minted, their initial Hero Attributes are set to 0%. Through NFT Hero Upgrade, players can enhance their NFT Hero Attributes up to a certain limit.

<table><thead><tr><th width="256">Hero Attribute</th><th>N</th><th>R</th><th>SR</th><th>SSR</th><th data-hidden></th><th data-hidden></th></tr></thead><tbody><tr><td>Health</td><td>4%</td><td>8%</td><td>30%</td><td>55%</td><td></td><td></td></tr><tr><td>Attack/Magic Attack</td><td>4%</td><td>8%</td><td>30%</td><td>55%</td><td></td><td></td></tr><tr><td>Defense</td><td>4%</td><td>8%</td><td>25%</td><td>55%</td><td></td><td></td></tr><tr><td>Magic Defense</td><td>4%</td><td>8%</td><td>25%</td><td>55%</td><td></td><td></td></tr><tr><td>Critical Rate</td><td>1%</td><td>2%</td><td>10%</td><td>20%</td><td></td><td></td></tr><tr><td>Block Rate</td><td>1%</td><td>2%</td><td>10%</td><td>20%</td><td></td><td></td></tr><tr><td>Hit Rate</td><td>1%</td><td>2%</td><td>10%</td><td>20%</td><td></td><td></td></tr><tr><td>Dodge Rate</td><td>1%</td><td>2%</td><td>10%</td><td>20%</td><td></td><td></td></tr></tbody></table>

{% hint style="warning" %}
Each Hero Attribute has its own upper cap. Once an NFT Hero reaches this cap, it cannot be further improved. Also, any gear and constellations equipped by the consumed NFT Heroes will be returned to your inventory.
{% endhint %}

### Boost Range

Each NFT hero offers a unique set of values that contribute to the ***Boost Range*** when consumed. These values determine the ***Minimum*** and ***Maximum*** values within which the NFT Hero Attributes can be enhanced through NFT Upgrades. When upgrading a desired NFT hero, a random value is selected from the ***Boost Range***, and the Hero Attributes are enhanced accordingly.

| Rarity | Minimum | Maximum |
| ------ | ------- | ------- |
| N      | 0.33%   | 0.67%   |
| R      | 0.67%   | 1.33%   |
| SR     | 2.50%   | 5.00%   |
| SSR    | 5.00%   | 10.00%  |

Once you complete the NFT Hero Upgrade, any heroes you consume will add to the ***Upgrade Level***. When the Upgrade Level hits Lv5, Lv10, Lv15, Lv20, Lv25, and Lv30, the target NFT hero will receive extra upgrades to their ***Hero Attribute*** and ***Mining Bonus***. The higher the Upgrade Level, the more significant the hero attribute enhancements, improved mining efficiency, and increased combat ability.
