# Training ## Overview
**Training your Genesis Heroes is the main way to earn rewards and progress in Onchain Heroes.** As Heroes level up, their base stats increase—unlocking better rewards, tougher content, and new ways to power up. *** ## Training Mechanics
Training is how Heroes level up in Onchain Heroes. To train, players choose from one of several **Trainer types**, each offering different **risk/reward profiles**. * Training costs [**$HERO tokens**](/items-and-assets/usdhero-token.md). * Increasing a hero’s level enhances their [base stats](/heroes/genesis-heroes.md#hero-stats) ( ATK and DEF) * After each training attempt, **heroes must rest for 24 hours** before they can train again > **Note:** A hero must wait 24 hours before training after its **first** battle in the season. ### How to Train 1. **Select a Trainer** – Each Trainer has unique odds and potential outcomes. Some offer safer, more consistent results, while others provide higher rewards with greater risk. 2. **Pay the Training Fee** – Training costs **$HERO** tokens, calculated using the level-up formula. 3. **Roll the Outcome** – Depending on the Trainer chosen, the training attempt may **succeed or fail**. A successful attempt increases the Hero’s level. > ⚠️ Failed attempts do **not** refund $HERO and still trigger the 24-hour cooldown. {% hint style="success" %} 💡 Strategic Trainer selection is key to efficient progression—balance risk tolerance with your long-term goals. {% endhint %} ### Training Cost Formula **$HERO Cost** = `(Level * 10000) / (69 + Level)` > eg. To level up from **10 ➝ 11**, the cost is **1265.82 $HERO**. *** ### Trainer Types **There are three unique Trainers**, each with different risk/reward dynamics:
