Like normal objects, an animated blade has Hardness. This Hardness reduces any damage the blade takes by an amount equal to the Hardness. Once an animated blade is reduced to fewer than half its Hit Points, or immediately upon being damaged by a critical hit, its construct armor breaks, and its Armor Class is reduced to 14.
