Now that StarCraft 2 has been released, we can begin to look forward to Diablo 3 with renewed fervor. Blizzard has revealed a new feature of the game today: artisans that travel with your party as you go adventuring. These artisans can level up, use materials you give them to craft new items, and will give you quests before you earn their loyalty. Want to add some sockets to your favorite weapon? Now you can.
