Powerful Fist

You know how to wield your fists as deadly weapons. The damage die for your fist changes to 1d6 instead of
1d4. Most people take a –2 circumstance penalty when making a lethal attack with nonlethal unarmed attacks,
because they find it hard to use their fists with deadly force. You don’t take this penalty when making a lethal attack with your fist or any other unarmed attacks.
