Expoint Cost: 3
You have been blessed with an unusually thick hide which can stand up to repeated blows. In effect, this gives you a bonus to your armor score which is in addition to any manufactured armor you may be wearing. Each time you take this Trump, you may add +1 to your armor score. This bonus applies even when you wear no armor, since it is a representation of your natural toughness. It also works just fine in combination with regular armor. You may take this Trump multiple times.
