Your Armor Score includes the armor’s base value (shown in the “Base Score” column) plus any permanent bonuses your character has to their Armor Score from other abilities. When your character takes damage, you can mark one of the small shield symbols next to your Armor Score (called an Armor Slot), then reduce the severity of the damage by one threshold: Severe to Major, Major to Minor, or Minor to None. You can only mark one Armor Slot per attack, and you have a number of slots equal to your Armor Score.
