HeroPoints are HeroMart's special in-game currency that lets you unlock exclusive gear in several of Artix Entertainment's games, including AdventureQuest Worlds, DragonFable and EpicDuel, when you purchase specific HeroMart products!
HeroPoints do not replace in-game codes, they are a separate reward received for specific products. Certain HeroMart products will always receive in-game codes with specific in game items, such as calendars.
