Once players wear their equipment items, it is bound (unless it has grey quality), and after that players can’t trade or auction it. The only equipment items that don’t go by this rule are Dagger of Roaring, The Staff of Roaring and Spear of Roaring. Players can receive these weapons on a quest in the Hanging Gardens. They are of green quality and can never be bound. They are great if you are a low level character because they deal the damage of a level 60 weapon and don’t have a level requirement. You should save them for your toons. Their AH value is around 200 gold.
