Once worn, the item is bound (unless the item is of grey quality), and can no longer be traded or auctioned. The only exceptions are The Staff of Roaring, Spear of Roaring, and Dagger of Roaring. These weapons are recieved from a quest in the Hanging Gardens. They are green and never bind. They are excellent for low level characters because they do not have a level requirement and hit the damage of a level 60 weapon. Save them for your toons. They also have an AH value of approximately 200 gold.
