Path of the brawler

While forgoing armour, Other barbarians still tend to use weapons. Not you however. Far from the precise martial arts of a monk, your fighting style is scrappy and involves knocking your opponent around and using your weight and power to your advantage. 

Unarmed fighting

Starting when you take this subclass at third level you are proficiency in unarmed strikes which now deal 1d6 plus your strength score damage. Additionally, when you use your reckless attack you can use a bonus action to either shove or grapple the same creature you used your reckless attack on.

Grapple slam

At sixth level you can slam a creature you are grappling into an object or creature. If you are grappling a creature you can use that creature as an improvised weapon (add your proficiency bonus to this attack). Doing so deals 1d6 damage to both the target of your attack and the creature you are grappling. If you make this attack as a ranged attack you can use strength instead of dexterity. Once you use this feature you drop the creature you used as a weapon.

Immovable juggernaut

At 10th level you are an unstoppable tank on the battlefield. While you are raging, if you have to make a strength saving throw, you can double your strength score. If the saving throw was to avoid getting moved against your will and your fail, you reduce the distance you get moved by 5 feet.

Ultimate slam

At 14 level, you can slam both fists into the ground to hit multiple people at once. When you use your reckless attack you can expend both of your attacks. When you do so, instead of making an attack roll, any creature standing in a square you choose within 5 feet of you as well as to the sides and in front of that square must make a dexterity saving throw. On a fail they take 2d8 damage or half as much on a success.
