Tsubute

The opposite of shuriken in many ways, tsubute are small, blunt, disc-shaped stones that have been ground down deliberately to be used as thrown weapons. Ninja skilled in the use of the tsubute can easily improvise a substitute if the weapon is not available; any round st0ne will suffice. Tsubute have very little value as offensive weapons and are used more as a tool for distraction and harassment. Because of their small size. tsubute do not add the wielder's Strength to their DR when used as ranged weapons, and their damage dice do not explode.
