Construct Armor (Hardness 10) Like normal objects, an animated furnace has Hardness. This Hardness reduces any damage the furnace takes by an amount equal to the Hardness. Once an animated furnace is reduced to fewer than half its Hit Points, or immediately upon being damaged by a critical hit, its construct armor breaks, removing the Hardness and reducing its Armor Class to 26.
