Unarmed Strike Master

Years of training with your fists have allowed you to become swift and deadly fighter in combat. 

- When you use the Attack action with an unarmed strike or a natural weapon on your turn, you can make an additional attack as a bonus action, assuming you are using no shield and wielding no weapon

- While you are fighting with unarmed strikes or natural weapons, other creatures provoke an opportunity attack from you when they enter the reach you have with that attack.
