Pugilism Mastery

You've learned how to use your body effectively by putting your entire weight behind your unarmed strikes. You gain the following benefits:

• Increase your Strength or Dexterity score by 1, to a maximum of 20.
• Before you make an attack roll with an unarmed strike, you may choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the attack's damage roll.
