Revised Path of the Berserker

(This is an attempt to fix the Berserker barbarian, y'know, the one from the PHB that nobody ever picks because totem warrior exists.)

For some barbarians, rage is but a means to an end - that end being when your enemies' insides are on the outside. The Path of the Berserker is for those wanting to get stuck in the fight, kick tail and take names and you're all out of names.

Frenzy

Starting when you choose this path at 3rd level, you can go into a frenzy when you rage. If you do so, for the duration of your rage you can make a single melee weapon attack as a bonus action, however when you hit an enemy with a melee weapon attack as your bonus action, the enemy you hit with said attack must use their reaction to make a single melee weapon attack against you.

Mindless Rage

Beginning at 6th level, you can’t be charmed or frightened while raging. If you are charmed or frightened when you enter your rage, the effect is suspended for the duration of the rage.

Mighty Presence

Beginning at 10th level, you can use your action to frighten or challenge someone with your presence. When you do so, choose one creature that you can see within 60 feet of you. If the creature can see or hear you, it must succeed on a Wisdom saving throw (DC = 8 + your proficiency bonus + your Strength modifier) and either be frightened of you for 1 minute. Or you can instead begin to insult, mock and/or taunt the chosen target into an enraged state for 1 minute, during this state the target can only use it's actions on each of it's turns to get within 5 feet of you via the most direct path possible and make as many melee weapon attacks against you as it can, the creature also cannot willingly move away from you for the duration. Both these effects end early when you become incapacitated or drop to 0 hit points, additionally, only one creature can be frightened of you and only one creature can be enraged by you at a time.

Retaliation

Starting at 14th level, when you take damage from a creature that is within 5 feet of you, you can use your reaction to make a melee weapon attack against that creature.
