The bone-based battering ram can withstand about as much damage as its wooden counterpart. The Ram serves to destroy walls for the Undead with the bodies of their victims. The Bone Ram is indistinguishable from other Undead units, held together by the forces of death. They are superior to machines in that they repair themselves after every combat by literally pulling themselves back together. But, as such, they are affected by a Cleric's Turn Undead ability.
