Metal Eraser

Metal Eraser is a golem type monster in The World with a stone ball as body and two arms made from stone pillars, which are not connected with the body. It uses either one of them to damage the party with a simple punch (it can use its right arm as well as its left one), or both at once by slashing them together three times to crush a single target. Despite the fact that a Metal Eraser can levitate while hitting the party, it will use its arms as legs for walking around.
