This fighter has an object designed to be worn over their knuckles for the purpose of increasing the force of their unarmed strikes; though this type of item is often referred to as 'brass knuckles' they can be made of a variety of materials. They improve the unarmed attacks of a fighter wearing them.
Unarmed: Close combat attacks made with this weapon are considered to be unarmed.
Melee: Attacks with this trait can be used during close combat without penalty.
Pulverize: After making an Injury roll for a successful attack that has this trait, the attacking player can roll a D6. If the result is equal to or higher than the target's unmodified Toughness, or is a natural 6, they can change one Injury dice from a Flesh Wound result to a Serious Injury result.
