Minecraft wiki entry for Armor, associated text: In Java and Bedrock editions‌[upcoming: BE 1.18.30], armor can further protect the player through a second attribute, generic.armor_toughness. Normally, armor nullifies a lesser portion of damage from attacks that deal greater damage.[2] Armor toughness resists this effect, mitigating the power of strong attacks.[3] By default, only diamond and netherite armor provide toughness, with each piece granting +2 toughness for diamond and +3 for netherite.
