Weightstones are items that will enchant or buff a weapon (a blunt weapon) to increase the damage that the weapon does. Sharp items takes Sharpening Stones and not weightstones. Some weightstones will also increase critical strikes. These buffs will last an hour from the time of application and it will have a special icon on the top right side of your screen to indicate how much longer the buff will be on your weapon.
These items are made from blacksmiths of varying degree of skill and can be found from them via guilds and the auction house on the server of your choice. It’s a nice little way to pack a little extra punch to your fight and well worth the small price it is should you find yourself having to pay for them. Most of the time a friend in the game will give them to you prior to battle, especially if you are in a raid group.
