Bruiser

While most of your ilk are subtle and rely on their wiles, they are still vulnerable to the threat of overwhelming physical force...which is why even the most insidious viper will always make sure to keep some muscle close by at all times

Disclaimer: I did not make this subclass. I only moved it from a google doc to beyond. I don't take credit for it.

Ruffian’s Armament

You use your sneak attack to strike at vitals and become a potential threat on the battlefield, and can use less-refined weaponry to do so as well. Starting at level 3, you find new ways to utilize your Sneak Attack. Any weapon wielded in one hand is considered to have the finesse property while you use it.

 

In addition, you can use the alarming appearance of certain weapons to trigger your sneak attack. Any weapon with both the Heavy and Two-handed property that lacks the Special property can trigger Sneak Attack. Save for this lifted weapon restriction, you follow all the other rules for Sneak Attacks.

Two Man Con

Starting at level 3, you can cause yourself to occupy your opponent’s focus, allowing allies to slip in and exploit their distraction. After you land a strike on a target, they have disadvantage on perception checks to spot your allies until the end of your next turn.

Exposure

Starting at level 9, you can aid your allies with a sudden motion or warning. When an ally attacks an enemy within five feet of you, you can use your reaction to grant the first attack roll advantage. Also, when an attacker that you can see hits an ally within 5 feet of you with an attack, you can use your reaction to halve the attack's damage against them.

Bruiser

Your physical presence becomes imposing. At 13th level, you gain proficiency in the Intimidation skill. If you are already proficient in it, you gain proficiency in one of the following skills of your choice: Athletics, Deception, Perception, Sleight of Hand.

 

Your proficiency bonus is doubled for any ability check you make that uses Intimidation. You receive this benefit regardless of the skill proficiency you gain from this feature.

 

Additionally, when you take the Help action to assist in a check that you add double your proficiency bonus to, instead of granting advantage you can choose to consider any roll of 9 or lower as a 10.

Alleycat Reflexes

At level 17, when you pass a dexterity save two creatures of your choice within 5 ft automatically succeed on that save as well.
