Path of the Frenzied Berserker

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 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 on each of your turns. You can use this feature a number of times equal to your strength modifier ( minimum of 1). At 14th level you can make two melee weapon attacks instead of one.

Devastating Blow

You channel your rage into massive blow pouring your own vitality into the attack with reckless abandon. At 3rd level, while you are raging, once per turn you make a melee weapon attack dealing 2x weapon damage + 1d10 damage when you sacrifice one hit die. You can add an extra hit die to the attack at 6th, 9th, 12th and 15th level. You can use this feature a number of times equal to your strength modifier (minimum of 1) once you expended all uses of this feature, you can’t use it again until you finish a long rest.

Mindless Rage

Beginning at 6th level, you mind has become so chaotic that it has projection against mind altering effects, whether you are raging or not.

• 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. 
• You have advantage on Wisdom saving throws against charmed or frightened
• You gain resistance to Psychic damage.

Retaliation

Starting at 6th 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.

Savage Bulwark

Using the strength granted to you by your rage you charge to the defence off your allies sacrificing your own vitality before attacking your enemy. When you reach 10th level, when you see an ally creature take melee weapon damage within 30ft, you can use your reaction to move into that creatures space and take the incoming damage instead and then make a melee weapon attack against that creature. You gain a bonus to the attack that is equals to half the damage that was dealt to you.

Mighty Frenzy

Your frenzy increases in power, you can now make a two melee weapon attack as a bonus action on each of your turns after this one. You can use this feature a number of times equal to your strength modifier ( minimum of 1).
