[[Artisans]]: "Vendors 2.0," these NPCs are merchants, quest-givers, and information sources. They follow the player throughout the game, traveling in a [[caravan]] between the acts, and in addition to the standard item buying and selling, they can [[craft]] new semi-random items from special [[recipes]], as well as [[enchant]], [[socket]], and [[repair]] items . Artisans can even be [[trained]] up to higher levels, giving them better skills.
