Armor Bonus

An armor bonus represents a protective barrier that makes attacks less likely to reach and harm a target. It applies to Armor Class and is granted by armor or by a spell or magical effect that mimics armor. Armor bonuses don’t stack with other armor bonuses, but they do stack with all other bonuses to Armor Class (such as a Dexterity bonus). Armor bonuses sometimes specify that they apply only to your Energy Armor Class (EAC) or your Kinetic Armor Class (KAC). Most suits of armor (see Chapter 7) provide armor bonuses to both EAC and KAC, though the specific armor bonuses a suit provides to each value often differ, as noted in the armor’s description. An armor bonus that doesn’t specify which Armor Class it applies to applies to both.
