World of Warcraft/Professions/Blacksmithing

In blacksmithing, a character creates weapons and armor from smelted bars of metal and in some cases the item that the blacksmith makes will also require gems or diamonds of some sort. Being a blacksmith is especially useful for a warrior or some other heavy armor wearing character. By being a blacksmith that character is able to make all their own armor and weapons. There would be nearly no practical use for a mage to be a blacksmith—since they can only wear cloth armor—except if they were to sell the products at the auction house. That is not always possible either, because certain items that a blacksmith makes in the higher levels of their craft are soulbound, meaning he cannot sell them at the auction house.
