World of Warcraft is a virtual reality, massively-multiplayer online role-playing game that owes part of its complexity to players having many professions to choose from. These professions are distinguished from other skills (such utility abilities, combat skills, and spells) by their connection and contribution to the virtual economy of the game. They represent skills that provide goods and services to other players from players. There are ten primary professions from which a character can select. Every character is allowed to learn up to two of these main or primary professions and all of the three available secondary professions.
