How much bashing can undead flesh take?
Most forms of bashing attacks simply do not affect vampires, at least not in the same way as mortals. The impacts from a baseball bat still hurt, and the body can ache for hours until healed. However, vampires simply DO NOT suffer additional health effects of collapsed lungs, a stunned heart, internal bleeding, or a punch to the kidney. Since bashing is not very effective on dead flesh, vampires only take half damage (rounding down).
