Path of the Berserker (Improved)

Berserker but better.

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.

Berserker's Rage

At 3rd level, you stride into battle with fearless fury. When you enter a rage and on subsequent turns after entering a rage, you can make a single melee attack or an improvised action involving a Strength check as a bonus action on each of your turns for the duration of your rage. You can’t be Charmed or Frightened while raging. If you're Charmed or Frightened when you enter a rage, the effect is suspended for the duration of your rage.

Shivers

At 6th level, you perceive your surroundings as much with your instincts as you do with your other senses. You gain a bonus to your Passive Perception and your Perception(Wisdom) checks equal to half your Barbarian level(rounded down). Due to the extent that you've accepted instinct into your psyche, you also gain resistance to Psychic damage.

Unbound

At 10th level, pain doesn't matter anymore; you're no longer hindered by the feeble limitations of your body. You can add your rage damage bonus to Strength checks and saving throws while raging. If you gain levels of Exhaustion while raging, the effect is suspended for the duration of your rage. If you have any levels of Exhaustion when you enter a rage, the effect is suspended for the duration of your rage.

Fanatic

Starting at 14th level, your reflexes are sharpened by your ravenous appetite for battle. When you take damage from a creature that is within your reach, you can use your reaction to make a melee attack against that creature.
