Tinker's tosser

The tinker's tosser is yet another in a long line of mechanical arms, this one a sizeable model attached to a backpack containing its phlogiston power source. A hand mounted in the end of the arm can hold anything from a rock to a dagger, while crosshairs hanging in front of the wearer's eye allow him to select a target. Properly loaded and aimed, the tosser throws its payload at the target.
