▣ Hero ExchangeGame Guide
- The Hero Exchange becomes available when the Hero Hall reaches Lv.10, and as the level of the Hero Hall goes up, the number of heroes you can sell increases. - You can trade heroes at the Hero Exchange. - The trades are made exclusively by mileages. ※ You can obtain mileages by using gems. > 1 mileage per 100 free gems spent > 1 mileage per 10 paid gems spent > If you spend less than 10 paid gems or 100 free gems at purchase, you will not obtain any mileages. > Please be cautious that using paid gems in place of free gems will give you the mileage equivalent to those when you spend free gems. ※ The images of this guide may not be those of the latest version due to updated progress.
