# Energy & Recharge

### Overview

<figure><img src="/files/pRLvHigWgl6R3VluUDCS" alt=""><figcaption><p><strong>Legend of Arcadia official marketplace website</strong></p></figcaption></figure>

When starting Legend of Arcadia, it’s essential to focus on the Adventure game mode to gain Energy and Experience (EXP). Energy is crucial for maximizing NFT hero mining efficiency and purchasing additional Arena challenge attempts. Energy can be obtained by burning NFT heroes, completing Labyrinth and Adventure rewards, Quest rewards, and winning World Boss betting rewards. Energy is used as fuel for NFT heroes during mining, purchasing extra challenges in the Fervor Arena, and placing final damage bets in World Boss challenges.

## How to acquire Energy in Legend of Arcadia?

To obtain energy, players can consume ***idle NFT heroes*** from their inventory, with different rarities providing varying energy points. It is recommended to use N-heroes to obtain energy as they provide the best cost-effectiveness. Players can also acquire a small amount of energy through Labyrinth and Achievement Rewards based on their progress. With enough energy, players can achieve maximum mining efficiency and gain more rewards in the game.

The amount of energy recharged depends on the ***rarity*** and ***additional attributes*** of the consumed hero. The higher the rarity and additional attributes of the NFT hero, the more energy recharges. Players can enhance their NFT heroes' additional attributes by upgrading them on the Legend of Arcadia official website.
