Rougish Profession- Bruiser

You focus more on thuggish, brute force tactics. You are the reason people don't like taking back alleys.

Thuggish

Starting at 3rd level you gain proficiency with Charisma(Intimidation) if you don’t already have it. Your proficiency bonus is doubled for any ability check you make that uses this proficiency.

Fighting Dirty

At 3rd level when you take this subclass the idea of a fair fight is a joke to you. You can use your Cunning Action to apply a poison to one weapon, make a grapple check or attempt to knock a Medium or smaller creature prone.

Sucker Punch

At 3rd level when you take this subclass you become proficient with Unarmed Strikes, hereafter referred to as Sucker Punch, they are stronger (1d4 + Strength modifier) and increase in power as you level up in this class. You can use your Cunning Action to make a Sucker Punch after you take the Attack Action. Sucker Punch increases to 1d6 at 5th level, 1d8 at 11th level and 1d10 at 17th level.

You cannot apply Sneak Attack to any attack other than a Sucker Punch but Sucker Punch always gains Sneak Attack unless you have disadvantage on the attack roll.

Haymaker

At 9th level you can now use your Cunning Action to make two Sucker Punches instead of one, but only the first one benefits from your Sneak Attack.

Mobbing and Mugging

Starting at 13th level while you have a Medium or smaller creature grappled, if an ally attacks the creature you are grappling you can grant their first attack your Sneak Attack as your Reaction. If an enemy, other than the creature you have grappled attacks you, you can use your Reaction to make a Strength check versus the grappled creatures Strength. If you succeed you have the attack target the creature you're grappling instead of you. If you fail the attack still targets you and you lose the grapple.

Additionally, while you have a Medium or smaller creature grappled, you have advantage on Dexterity(Sleight of Hand) checks made to plant or pickpocket something on them.

Thick Necked

At 17th level you gain resistance to bludgeoning, piercing, and slashing damage. Additionally in the event you are reduced to 0 hit points, you can drop to 1 hit point instead. You can’t use this feature again until you finish a long rest.
