Primal Path: Path of the Brute

Diogenes's Base Idea The Brute, a Barbarian dedicated to raw physical power and unarmed combat. He can kill a lion with his teeth and radiates an aura of alpha power. Men want to be him and women name their vibrators after him. The kind of character that wrestles bears, punches out dragons and blows out the Lich's eye-lights before kicking him down the stairs. Whenever he kicks ass, which he dishes out in significant portions, he grants his allies inspiration and leaves his enemies quaking in fear.

Raging Fist

Starting when you choose this path at 3rd level, when you are raging and hit with an unarmed strike, your rage damage is doubled.

Your unarmed strike deals 1d4 bludgeoning damage, and at 6th level onwards count as magical for the purpose of overcoming resistances and immunity to nonmagical attacks and damage.

Brutish Grappler

Also at 3rd level, when you attack a target whom you are grappling, your melee attacks are made at advantage. Additionally, if your attack is unarmed and if it crits when you hit an enemy you are grappling any static numbers such as your bonus rage damage is doubled.

When you have grappled a creature, your movement speed is not halved if they are one or more sizes smaller than you. When you reach 6th level, your movement speed is not halved if they are the same size or smaller than you. Lastly, when you reach 10th level your movement speed is also not halved if they are one size larger than you.

Bulging Charisma

At 6th level, your bulging... muscles add to the general aura that surrounds your every movement. When you make a Charisma (Intimidation), Charisma (Persuasion), or Charisma (Performance) skill check, add your Strength modifier to the roll. This doesn't apply if the target of the skill check can't see you.

Aura of the Alpha

Also at 6th level, you generate an aura of raw power and aggression. Enemies within 15 feet of you have disadvantage when making Charisma saving throws or when trying to make Charisma (Intimidation) checks.

Throw Attack

Beginning at 10th level, when you are grappling a creature, you can use one of your attack actions to throw the creature. It travels a number of feet equal to your Strength ability score, or double that if you are raging. When it hits an object or lands, can make a Dexterity saving throw to land in a way favorable to it. The DC is equal to 8 + your proficiency bonus + your Strength modifier. If they fail, they land prone and take bludgeoning damage equal to your Strength score, or twice that if you were raging when you threw them.

Brutality

From 14th level on, every time you kill a creature it's a spectacle. When you kill a creature, you can use your bonus action to do so in a particularly brutal way. Allies that can see this event make their next attack roll or saving throw with advantage, and enemies that see this event must make a Charisma saving throw with a DC equal to a Charisma (Intimidation) check that you roll as part of this bonus action. If they fail, they are frightened of you for 1 minute unless you drop to 0 hit points during that minute.
