Natural Weapon Master

Your extensive training gives you both control and the confidence to relinquish that control. You gain the following benefits:

• Your unarmed and natural weapon attacks score a critical hit on a roll of 19 or 20.
• Before you make a melee attack unarmed or with a natural weapon that you are proficient with, you can choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the attack's damage.
