When you choose this archetype at 3rd level, you adopt a frenzied fighting style that puts you at ease when outnumbered and surrounded. You gain a +1 bonus to attack rolls for each enemy creature after the first within 5 feet of you.

Bloodthirst

At 3rd level, you begin to crave combat and bloodshed. Your first attack on each of your turns scores a critical hit on a roll of 19 or 20.

If this attack scores a critical hit, you enter a fit of rage for a number of rounds equal to your Constitution modifier (minimum of one). While enraged, your attacks deal an additional 1 damage. This increases to 2 damage at level 7, 3 damage at level 15, and 4 damage at level 18.

Titan's Grip

At 15th level, you bolster your strength and become able to wield mighty weapons with ease. You can dual wield weapons that have the two handed and heavy properties. While doing so, your speed is reduced by 10 feet and you only gain the benefit from the War Machine feature for your main handed weapon.

Carnage

At 18th level, you learn how to swiftly lash out with all of your fury. Attacks you make with weapons that have the heavy and two handed properties grant you a stack of Recklessness.

You can use this ability a number of times equal to your Constitution modifier (minimum of one). You regain all expended uses when you finish a long rest.

Revenge

At 7th level, you are able to swiftly strike foes. When you are hit by an attack, you gain a +1 bonus to the next attack you make against the attacking creature. This bonus stacks up to a maximum of +3.

Thunderclap

At 10th level, you can let out a thunderous stomp. Once per turn when you take the attack action, you can substitute one of the attacks for a Thunderclap. Enemy creatures within 5 feet of you must make a Constitution saving throw. A creature takes 2d8 thunder damage on a failed save, or half as much damage on a success.

At 15th level, creatures within 10 feet of you have disadvantage on attacks made against targets other than you. Additionally, if you are benefiting from the Dodge action, damage you take is reduced by an amount equal to you Constitution modifier.

Shield Wall

At 18th level, you can become a shining beacon of defense. When you take damage, you can use your reaction to harden your defenses. For a number of rounds equal to your Constitution modifier (minimum of one), you gain resistance to all damage.
