Jawline Sharper than Diamonds

Your character has developed an incredibly sharp jawline which is so strong that you gain the following benefits:

• Increase your Strength, Constitution or Charisma score by 1, to a maximum of 20.
• Your jawline is a natural weapon, which you can use to make unarmed strikes. If you hit with it, you deal piercing damage equal to 1d12 + your Strength modifier. You take 1d4 bludgeoning damage every time you hit an enemy with your jawline.
• You have such a mighty presence that you have advantage on all Intimidation skill checks when the targeted creature has direct line of sight to your jawline.
