Martial practitioners of the Way of the Fist are the ultimate masters of unarmed martial arts combat.
As their close brethren the monks they also make careful study of a magical energy called Ki.

Ki is an element of the magic that suffuses the multiverse—specifically, the element that flows through living bodies.
Students of the Way of the Fist harness this power within themselves to create magical effects, and exceed their bodies physical capabilities.
some of their special attacks can hinder the flow of ki in their opponents, or even outright kill them in one hit. 
Using this energy, Way of the Fist practitioners channel uncanny speed and strength into their unarmed strikes.

As they gain experience, their martial training and their mastery of ki gives them more power over their bodies and the bodies of their foes.
Because of their rigorous unarmed and Ki trainings, they don't have the time to get higher than proficient in their weapon of choice, after all their bodies are their greatest weapon.
There's another reason why they shy away from weapons, their internal Ki is enhanced in a way that causes it to negate magic, which means that students of the way of the fist cannot use any and all magical items.

Way of the Fist practitioners can be of any alignment, they are encouraged to find their own way in the world,
and at the age of 16 they no longer allowed to train with their masters, and encouraged to go outside and wander the world,
hopefully to learn about themselves and find an expression to their talent, may it be neutral, lawful or chaotic.
