Boxing (fighting style)

Boxing is a fighting style. While you have this style, you gain these benefits:
     You have deliberately trained with unarmed strikes, gaining several benefits:

• Your unarmed strike can deal bludgeoning damage equal to 1d6 + your Strength modifier.
• If you make an unarmed strike as part of your Attack action and are not wielding any shield or weapon, you can make an extra unarmed strike as part of that same action. You don't add any ability modifier to the damage roll of this extra strike.
• At the start of your turn, any one creature you are grappling takes 1d6 bludgeoning damage if your hands are otherwise empty.
