Blood Drinking: A blood drinking weapon must have a ruby embedded along its surface. In response to a mental command, it can store the bloodtrace of the next creature that it injures; see detect bloodtraces for more information on this effect. By touching it to an existing bloodstone, you can draw the imprint out of the other stone and into the weapon. A blood drinking weapon is considered to be a bloodstone for purposes of detect bloodtraces and follow the bloody trail. It can only store one trace at a time, but you may overwrite the existing trace as many times as you wish.
