As the first expansion for Guild Wars 2 (released 2015), Heart of Thorns requires the base game to access its content, significantly enhancing the Role-Playing Game experience. You journey into the vertical, multi-layered Heart of Maguuma jungle to confront the Elder Dragon Mordremoth. Key additions include the entirely new Revenant profession, account-wide Mastery progression for new abilities, and Elite Specializations that overhaul existing classes with new skills and weapons, deepening character customization within the existing level structure.
