Barbarian: Path of the Berserker

Enrage

3rd-level Path of the Berserker feature
Your anger can be sparked by the smallest slight. You can enter a rage using a Bonus Action or a Reaction when you take damage.

Frenzy

3rd-level Path of the Berserker feature
You can go into a frenzy when you rage. If you do so, you can immediately make a single melee weapon attack, and for the duration of your rage you can make a single melee weapon attack as a Bonus Action on each of your turns.

When your rage ends, if you have gone into a frenzy twice since your last short or long rest, you gain one level of fatigue.

Mindless Rage

6th-level Path of the Berserker feature
You have immunity to the Charmed and Frightened conditions while your Rage is active. If you are Charmed or Frightened when you enter your Rage, that condition ends on you.

Retaliation

10th-level Path of the Berserker feature
When you take damage from a creature that is within 5 feet of you, you can use your Reaction to make one melee attack against that creature, using a weapon or an Unarmed Strike.

Intimidating Presence

14th-level Path of the Berserker feature
As an Bonus Action, you can strike terror into others with your menacing presence, as you swell with primal power. When you do so, each creature of your choice within 30 feet of you—or 60 feet of you if your Rage is active—must make a Wisdom saving throw (DC equal to 8 + your proficiency bonus + your Strength modifier), provided the creature isn’t behind Total Cover. On a failed save, a creature has the Frightened condition for 1 minute. At the end of each of the Frightened creature’s turns, the creature repeats the saving throw, ending the effect on itself on a successful save.

Once you use this feature, you can’t use it again until you finish a Long Rest. If you’ve run out of uses of this feature, you can expend a use of your Rage, choosing not to activate the Rage and activating Intimidating Presence instead.
