Unarmed Specialist

You’ve developed the skills necessary to hold your own in close-quarters combat when unarmed. You gain the following benefits:

• You get +1 to your strength score 
• You can attack using an unarmed attack twice with an action or 4 times with multi attack. This also applies to bonus actions.
• With the discipline you have gained from fighting with your fists so often if a creature attacks you, with your reaction you can take half damage by using your hands to defend.
