A brick. Maybe the model of a 2x4 brick? But, it does 20 damage, has a small "splash" effect which breaks into parts of brick(maybe make the explode/fragments look like 1x1s? Lol) the splash damage is 5 each hit. It charges like a spear. If thrown at any brick smaller than 2x4, the brick with fakekill, like the brick knocked the brick out of place.
