Brute

Though the name is often thrown out like an insult, a brute is just someone willing and able to apply force to solve their problems. The simplest solution is often a straight line and brutes are capable of breaking through their obstacles where others would have to take clever paths. Brute fighters are a blunt instrument, an unrelenting force able to smash through tricky words and brilliant strategies with a simple and elegant strike to the brainpan.

Brute Strength

At 3rd level, you gain the ability to exert extra force into your swings. Whenever you hit a creature with a melee weapon attack, you can expend exertion points to deal an extra 1d8 bludgeoning damage per exertion point spent. The maximum amount of exertion points you can spend in this way on a single attack is equal to your proficiency bonus. 

Brutish Traditions

Also at 3rd level, you gain proficiency in one of the following combat traditions of your choice: Adamant Mountain, Tempered Iron, Tooth and Claw. When you gain this feature you can choose one of the maneuvers you know and replace it with another maneuver of the same degree or lower from your newly chosen combat tradition.  

Tough as Nails

At 7th level, your overbearing strength allows you to shrug off blows. Whenever you finish a short or long rest , you gain a number of temporary hit points equal to twice your Strength modifier. When you reach 15th level, you instead gain a number of temporary hit points equal to your Strength score.

Overpowering Strike

At 10th level, your attacks literally blow your opponents away. Once per turn when you make a melee weapon attack, you may choose to have the target make a Strength saving throw (DC 8 + your proficiency bonus + your Strength modifier). On a failure, you choose whether it falls prone or is moved 5 feet away from you.

Unstoppable

At 15th level, you gain advantage on saving throws made to resist being paralyzed , petrified , knocked prone , restrained , or any spell or effect of the compulsion school.

Overwhelming Onslaught

At 18th level, when you successfully hit the same target with two or more melee attacks in a single turn, you may spend 2 exertion points to deal extra bludgeoning damage equal to 2d8 + your Strength modifier. In addition, the target makes a Constitution saving throw (DC 8 + your proficiency bonus + your Strength modifier) or becomes stunned until the end of your next turn.
