Fighting pits, barroom brawls, and back alley scraps. All places where you thrive. You revel in the thrill of throwing punches, drinks, and maybe even the occasional chair. Monks who follow the Way of the Scrapper are almost always self-taught. When they are trained, it's never in a proper, upstanding monastery. These Monks are usually hired as extra muscle for establishments or bodyguards for those who can't afford knights in shining armor.

Barroom Brawler

Starting at 3rd level, you have advantage on athletics rolls to grapple. Furthermore, you do not suffer any penalties to attack rolls while grappling.

Additionally, improvised weapons count as Monk weapons.

Dirty Fighting

Starting at 6th level, you are no longer above hitting below the belt. When you hit another creature with a melee weapon attack, you can spend 2 ki points to hit them where it hurts. The target must succeed a Constitution saving throw or be Poisoned for a number of rounds equal to your Wisdom modifier. 

Sucker Punch

Starting at 11th level, you’ve learned to take advantage when someone's back is turned to you. Once per turn, you may spend 3 ki points to make an attack of opportunity against an enemy within 5 feet of you when they attempt to attack someone other than you. Your attack resolves before theirs does.

Furthermore, you always have advantage on attacks of opportunity.

Punch Drunk

Upon reaching 17th level, you can push past your limits to keep on swingin'. Having 0 hit points no longer renders you unconscious. You must still make a death saving throw at the start of your turn, and you suffer the normal effects of being damaged while making death saving throws.

Additionally, abilities that consume ki points have their cost reduced to 0 while you are making death saving throws.
