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.
Increasing a hero’s level enhances their base 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
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.
Pay the Training Fee – Training costs $HERO tokens, calculated using the level-up formula.
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.
💡 Strategic Trainer selection is key to efficient progression—balance risk tolerance with your long-term goals.
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:
