This is a stout leather gauntlet with a well-forged metal weight sewn into it over the knuckles. A strike with a ward cestus is considered an unarmed attack. If you take an All-Out Defense action, you gain an additional +1 deflection bonus to your AC, representing blows you block with the back of your protected hand. Your opponent cannot disarm you of a ward cestus. The cost and weight are for a single ward cestus.
