Warrior of the Shapechanger

You took the idea of transformation literally. Your interest in the schools of transmutation and illusion to give yourself the ability to adapt to every situation. Many Warriors of the Shapechanger become spies, which is why many look at them with suspicion.

Once per turn when you hit a creature with an Unarmed Strike and deal damage, you can expend 1 Focus Point to transform your fists into one of the following until the end of your next turn. These do not use your Reaction:

Claws of the Beast. You transform your fists into frightening claws to Rend a target with extra Slashing damage equal to one roll of your Martial Arts die plus your Wisdom modifier. You gain advantage on Opportunity Attacks. Your allies within 5 feet of you have Advantage on attack rolls until your hand transforms. 

Toxic Vines. You transform your fists into a tangle of thorny, poisonous vines allowing you to give the target an extra Poison damage equal to one roll of your Martial Arts die plus your Wisdom modifier.
