Armor toughness is an attribute of armor defense level in Minecraft that provides the player with extra protection from strong attacks. It is an additional layer of defense against incoming damage, and only diamond and netherite armors give armor toughness. Armor toughness reduces the amount of damage taken by the player per hit, and it affects the amount of damage that is required to penetrate each armor point. With no armor toughness, it takes 2 points of damage per armor point, meaning that 10 points of damage will reduce full diamond (20 armor points) to the equivalent of full iron (15 armor points) . The toughness level acts as extended life for a player when under attack. The armor toughness is not shown as a separate bar in the game, but it can be checked for each piece of armor from the inventory.
