The exception is the Scion, formerly a locked prestige class released in 2013, which is aligned with all three attributes. Each of these classes are aligned with one or two of the three core attributes: Strength, Dexterity, or Intelligence.
Players can choose from seven available classes to play as (Duelist, Marauder, Ranger, Scion, Shadow, Templar and Witch). While all players on a single server can freely mingle in encampments, gameplay outside of encampments is highly instanced, providing every player or party with an isolated map to freely explore. All areas aside from the central encampments are randomly generated for increased re-playability.
The game borrows heavily from the Diablo series, particularly Diablo II. The player controls a single character from an overhead perspective and explores large outdoor areas and caves or dungeons, battling monsters and fulfilling quests from non-player characters (NPCs) to gain experience points and equipment.
