Thug

You fight dirty - like, really dirty. You never learned how to fight properly, and you never saw the value of fighting fairly, anyway. Honor can't help you if you're crumpled on the ground getting your face bashed in, so you might as well be the one doing the face bashing. In the streets, only the strongest survive, and you're not looking to die anytime soon.

Bludgeoning Expert

When you choose this archetype at 3rd level, you gain proficiency with Flails, Mauls, Warhammers, and Medium Armor.

In addition, you learn how to get the most out of the dullest weapons - you can make a melee attack with a weapon that deals bludgeoning damage instead of a finesse or ranged weapon for your Sneak Attack feature.

Bully

Starting at 3rd level, you gain a penchant for fighting dirty. You can use the Bonus Action granted to you by your Cunning Action to grapple a creature.

You also gain an additional way to use your Sneak Attack - you don't need Advantage on the attack roll to use your Sneak Attack on a creature that is grappled, as long as you don't have Disadvantage on the attack roll. All other rules for Sneak Attack still apply to you. 

At 9th level, you can use the Bonus Action granted by your Cunning Action to shove a creature.

Truth By Terror

At 9th level, you can instill fear into the minds of your enemies to make them panic.

When you hit an attack against a creature that is Grappled, Prone, or Restrained, you can make a Charisma (Intimidation) check against the target, contested by its Wisdom (Insight) check. You automatically fail if the creature cannot be Frightened.

If you succeed, the target has Disadvantage on ability checks - this effect lasts for 1 minute, until you successfully use this feature against a different target, or until the target is no longer grappled, prone, or restrained.

Experienced Mobster

At 13th level, you become the monster that other monsters fear. You cannot be Frightened.

Coup De Grâce

At 17th level, you can finish off your victims while they are most vulnerable.

When you hit a creature that is Prone with a melee weapon attack, you can choose to score a critical hit instead. Once you do, you cannot use this feature again until you finish a short or long rest.
