Martial Arts Adept

As a Martial Arts Adept, you use your natural skill and use your body as a weapon to skillfully take down the mightiest of foes in battle with nothing but your fists.

Unarmed Strike

When you choose this subclass at 3rd level, your unarmed strikes now deal 1d4 + your strength or dexterity score. You can attack with these as an action. You can make one more unarmed strike as part of your action when you reach 9th level, 13th level, and 17th level. 

Nimble

Starting at 9th level, when you use the disengage action as a bonus action or action, add your proficiency bonus to your AC. Additionally, your movement speed is increased by 10 ft. If a creature makes an attack of opportunity against you in combat, you may make a melee attack against that creature.

Throw

Starting at 13th level, when a creature of the same size as you or smaller makes a melee weapon attack against you, you can use your reaction to reduce the damage done to you by as many d10's as your dexterity modifier + your dexterity modifier. If the damage is reduced to 0, make a contested Acrobatics check. On a success, the creature is knocked prone and loses all extra attacks and any actions or bonus actions.

Incapacitating Blow

Starting at 17th level, when you make a melee unarmed strike and hit, you can make a dexterity (sleight of hand) check to attempt to place your shot skillfully. The DC equals the target's AC + 2. On a success, the target is knocked unconscious for 1d4 hours unless somehow woken by another creature.
