The Brute

Unlike other rogues, they are often willing to forgo subtlety for brute force in the pursuit of their goals. Where other rogues prefer to rely on precise weaponry, a Brute can deliver equally devastating blows with a club, mace, or sword once they get their hands on an enemy. Any street urchin knows that ending up in a Brute's grip can be as dangerous as running into an assassin in a dark alley.

Brute Force

Starting at 3rd level, you gain proficiency with medium armor and Athletics. You can add double your proficiency bonus to any ability check you make in Athletics, and when you make a Charisma (Intimidation) check, you can use your Strength modifier instead of Charisma if your Strength is higher.

In addition, you can make Sneak Attacks with any melee weapon with which you are proficient unless it has the heavy or special property.

Shakedown

Also at 3rd level, you can use your Cunning Action to attempt to grapple a creature, and you gain an additional way to use your Sneak Attack; you don't need advantage on the attack roll to use your Sneak Attack against a creature you are grappling if you don't have disadvantage on the attack roll. All the other rules for Sneak Attack still apply to you.

Beatdown

Beginning at 9th level, when you deal Sneak Attack damage to a creature you are not grappling with a melee attack, you can attempt to knock the target prone. The target must make a Strength saving throw (DC = 8 + your Strength modifier + your proficiency bonus) or be knocked prone. A Huge or larger creature makes the saving throw at advantage. On a failure, it is knocked prone.

You can do this a number of times equal to your proficiency bonus, and regain all uses when you finish a long rest.

Forced Cover

Also at 9th level, you know how to keep a body between yourself and a threat. While you are grappling a Medium or Small creature, you have half cover against attacks from other creatures. If an attack misses you due to the +2 bonus to your armor class offered by half cover, you can use your reaction to force the attack to hit the creature you are grappling.

I'll Hold 'Em For You

By 13th level, you are used to working with others to beat down the opposition. A creature you are grappling has disadvantage on attack rolls against creatures other than you, and when an ally makes a melee attack against a creature you are grappling, you can use your reaction to grant that ally advantage on the attack roll.

Brutalize

At 17th level, your attacks are most fearsome against vulnerable opponents. Your Sneak Attacks deal an additional 3d6 damage against creatures that are grappled or prone.
