Far less mystical than most monks. Brawlers are brutal fist-fighters who honed their abilities in street-fights and bar-brawls. Brawlers focus more on physical perfection than spiritual perfection. They fight with more desperation and brutality, their techniques focused on violence rather than elegance. 

Closed Fist Technique

The brawler monk focuses more on physical fitness and martial arts mastery than mystical energy. At 3rd level whenever you make a Flurry of Blows you may declare each unarmed attack in the flurry a Style Strike gaining an additional effect on a hit. 

• Elbow Strike -  Make an additional unarmed attack after this one. The additional attack cannot be declared a style strike, and the damage dice decrease by 1 size (1d10 becomes 1d8, 1d8 becomes 1d6, 1d6 becomes 1d4 and 1d4 changes to 1 damage) 
• Hammerblow - The damage for this dice increases by 1 size (1d4 becomes 1d6, 1d6 becomes 1d8, 1d8 becomes 1d10, 1d10 becomes 1d12), you must have two hands free to declare an unarmed strike a hammerblow. 
• Headbutt - The target must succeed on a Constitution saving throw (DC = 8 + Proficiency + Strength) or take a point of exhaustion. Creature must have a head to be susceptible to this effect. 

Boxing Guard

At 6th level you can use your reaction to block a melee attack. When you do so, the damage you take from the attack is reduced by your unarmed strike damage + Strength modifier + Monk Level. If you reduce the damage to 0, you may spend 1 ki point to make a single unarmed strike against that opponent as part of the same reaction, if the target is within your reach.

Break Stuff

At 11th level, your fists count as adamantine. Whenever you make Strength checks to break an object you add your full proficiency bonus to the roll.

Knockout Punch

At 17th level, when you hit someone with an unarmed strike you may spend 3 ki points to attempt to immediately knock the opponent out. The target must make a Constitution Saving throw or fall unconscious if the target succeeds they instead take 10d10 bludgeoning damage.
