Path of the Berserker
3rd Level: Frenzy
You can go into a frenzy in battle. If you use Reckless Attack while your Rage is active, you deal extra damage to the first target you hit on your turn with a Strength-based attack. To determine the extra damage, roll a number of d6s equal to your Rage Damage bonus, and add them together. The damage has the same type as the weapon or Unarmed Strike used for the attack.
6th Level: Mindless Rage
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.
10th Level: Retaliation
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.
14th Level: Intimidating Presence
As a 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.
