# Leveling

### **Advancing Levels:** 

Elevating a hero's level enhances their Attack, Defense, and Health indices. It's important to highlight that while leveling up boosts a hero's power, it doesn't transform them into a higher-tier hero. You can increase your hero's level by utilizing GEMS tokens, with the cost escalating after each level-up.

Hero can advance to the next stage once they reach the pinnacle level of the previous stage. Utilizing $GEMS tokens for this advancement consistently enhances the hero's special skills and boosts their stats.
