Path of the Berserker (Rework)

For some barbarians, rage is a means to an end—that end being violence. The Path of the Berserker is a path of untrammeled fury, slick with blood. As you enter the berserker's rage, you thrill in the chaos of battle, heedless of your own health or well-being.

Frenzy

Starting when you choose this path at 3rd level, you go into a frenzy when you rage. For the duration of your rage you can make a single melee weapon attack as a bonus action, however the attacked creature can make a melee attack against you as a reaction. 

Impetuous Attacker

Beginning at 3rd level, when you activate you reckless attack feature you can choose to empower it. When you do so, all attacks made in that turn receive a damage increase equal to half you barbarian levels (rounded up). You can use this feature a number of times equal to your proficiency bonus. You regain any expended uses when you finish a long rest.

Intimidating Presence

Beginning at 6th level, when you take the Attack action on your turn, you can replace one of your attacks. When you do so, choose one creature that you can see within 30 feet of you. If the creature can see or hear you, it must succeed on a Wisdom saving throw (DC equal to 8 + your proficiency bonus + your Strength modifier) or be frightened of you until the end of your next turn. 

If the creature succeeds on its saving throw, it has advantage on all saving throws against this ability for the next hour.

Retaliation

Starting at 10th level, when you take damage from a creature that is within your reach, you can use your reaction to make a melee weapon attack against that creature.

Whirlwind Attack

Starting at 14th level, you can use your action to make a melee attack against any number of creatures within your weapon reach, with a separate attack roll for each target.
