You can spend Gems to purchase Hero Chests and items from the Black Market. You can also use Gems to refresh the Black Market instantly and to exchange for Coins. If you run out of energy while playing Forged Fantasy, Gems may also be used to purchase additional stamina.

You can buy Gems through in-app purchases in the Store. Gems are also awarded when leveling up or earning achievements. Gems are also available to be claimed on certain days in the Daily Log in calendar, and through Daily Quests.
