The way of the scumbag focus's only on getting the upperhand. They are creative and fight very dirty. 

Dirty Tricks

Starting when you choose this tradition at 3rd level, you have abandoned all honor with your attack style. Whenever you hit a creature with one of the attacks granted by your Flurry of Blows, you can impose one of the following effects on that target:

• It must succeed on a Dexterity saving throw or be knocked prone.
• It must succeed on a Constituion saving throw or be blinded blinded.

Rough and Tumble

At 3rd level you know that choking out your opponent is a common method in the streets and you are proficient. You can use your Dexterity (Acrobatics) check instead of a Strength (Athletics) check when you grapple an opponent. Additionally, when you hit a creature with an unarmed strike or an improvised weapon on your turn, you can use a bonus action to attempt to grapple the target. 

Creative Weapons

At 6th level you have learned to use the environment when you fight. You gain profiency in improvised weapons and you can use them as monk weapons. 

Quick Hands

At 6th level your time on the streets has taught how to take from others while fighting. You gain profiency in the slight of hand skill. Additionally, as a bonus action you can make a sleight of hand check to take something your opponent has on them. 

Taunt

At 11th level, you've learned to make fun of you're opponent while in battle. As a bonus action, you can make a Charisma (Persuasion) check contested by a creature’s Wisdom (Insight) check. The creature must be able to hear you, and the two of you must share a language.

If you succeed on the check , it has disadvantage on attack rolls against targets other than you and can’t make opportunity attacks against targets other than you. This effect lasts for 1 minute, until one of your companions attacks the target or affects it with a spell, or until you and the target are more than 60 feet apart.

First Hit

You hit when least expected. At 17th level, other creatures provoke an opportunity attack from you when they enter your reach.
