Way of the Boxer

Boxer's have a well developed constitution and are fully capable of taking punches. They are keen on targeting the opponents soft spots and throwing counter punches.

3rd: Opportunist

When a creature within 5 feet makes an attack against you and misses, they leave themselves vulnerable for a counter attack. You can use your reaction to make an unarmed strike against that creature.

Additionally, you can spend a ki point to make 2 unarmed strikes instead of 1.

3rd: Gritted Teeth

Boxers  train in throwing punches but also taking punches. When you fail a saving throw that would cause you to be stunned, incapacitated, or knocked prone, you can spend 1 ki point to reroll the saving throw.

Additionally, if you are subjected to an effect that would cause you to move against your will, you can use your reaction to stay in place.

6th: Haymaker

Your haymakers are fierce and formidable! Attacks made as bonus actions, reactions, or a stunning strike count as haymakers and briefly jar an opponent's senses. 

When you hit a creature with one of these special attacks, they cannot take reactions until the end of your next turn.

When a creature fails a saving throw against your stunning strike, they are additionally knocked prone. If they succeed a saving throw against your stunning strike, have them roll a strength saving throw against your ki save DC or be knocked prone. When you spend a ki point with the opportunist feature to make an additional attack, have the target roll the strength save or be knocked prone.

11th: Hammer Punches

You can swing at full force throwing hammer punches on creatures beneath you. When you hit a creature that is prone or at least one size smaller then you with a melee weapon attack, instead of rolling damage dice, you instead deal the maximum damage of each attack.

17th: Uppercut

When you roll a 20, you have found an opening for an uppercut! 

When you land an uppercut, the target is knocked prone and paralyzed until the end of your next turn.

If you roll a 19 you can spend 2 ki points to throw an uppercut, and if you roll an 18 you can spend 5 ki points to throw an uppercut.
