Short Sword of Backstabbing: The Shadow's Blade +2
The Shadow's Blade was created to be the perfect assassin's tool. It is highly sought after by any who settle differences with a blade, and many that possess it do not do so for long. In the hands of any character this is a +2 magical weapon, but in the hands of a thief it is especially potent. When a thief makes a backstab attempt with this short sword, it allows him to attack as if four levels higher than his actual experience level, with corresponding improvements in THAC0, and damage multiplier on a successful hit.
