Forgive me if this is in the rules or the forums, but my searching hasn't turned up anything. Does equipping a shield count as armor? I know there's no "armor" keyword on the shield cards, but they are hunks of metal you put between you and the bad guys. I ask becuase Nanok of the Blade loses his Heroic Ability if he equips armor, but as a Knight most of his skills revolve around a shield. So will handing him a shield cause him to lose his Ability?
