World of Warcraft: Cataclysm introduces the epic new skill of Archaeology—a secondary profession that a player of any level can learn and use. Best of all, many rewards are "Bind to Account" items so they can benefit all of your characters.
Archaeology in the World of Warcraft rewards players with experience for scouting artifact fragments and with unique armor, weapons, pets, mounts, and vanity items for completing research projects. As your character gains skill levels in Archaeology it allows you to find and complete more powerful artifacts from fragments collected in all of Azeroth and the Outlands.
