Brutal Scoundrel

Other rogues are agile acrobats, cunning thieves, and skilled tricksters, but not you. You embody the more brutish side of the seedy underworld, choosing to solve your problems with your fists. To some you might be a skilled bodyguard or bouncer, to others you're a bruiser and a thug. The truth is probably somewhere in between. Whatever your reputation one thing is clear, you're not to be trifled with - at least, not if the trifler values their legs.

Threatening Disposition

When you choose this archetype at 3rd level, you gain proficiency in the Intimidation skill if you don't already have it, and your proficiency bonus is doubled for any ability check you make that uses that proficiency.

In addition, you can use a bonus action to intimidate enemies in combat instead of an action. Your DM will decide when and if it is appropriate to intimidate enemies in combat.

Iron Knuckles

Starting at 3rd level, you become as deadly with your fists as other rogues are with their weapons. You gain the Tavern Brawler feat, and can apply your Sneak Attack damage to your unarmed strikes or attacks made with improvised weapons.

Extra Attack

Starting at 9th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.

Unrelenting Assault

Starting at 13th you gain the ability to punish those who would try to escape your grasp. You gain the Sentinel feat, and whenever a creature who was previously grappled by you within the last round attempts to move outside of your reach, you have advantage on the triggering opportunity attack.

Knockout Punch

At 17th level, you gain the ability to render an enemy unconscious with a single punch. When you score a critical hit using your unarmed strike, the target creature must succeed on a Constitution saving throw (DC is 8 + your strength modifier + your proficiency bonus) or be rendered unconscious for 1 minute.
