Berserker, Variant (5e Subclass)
From D&D Wiki
Path of the Berserker, Variant
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 after this one. When your Rage ends, you cannot take any action and your speed is reduced by half until the end of your next turn as your body is tired by the end of it.
Break and Shatter
Beginning at 10th level, While in Frenzy, you can spend a hit die to gain an additional 1d12 damage on an attack that hits. You may only spend a maximum of three hit die when using this feature.
Starting at 14th level, when you take damage from a creature that is in your reach, you can use your reaction to make a melee weapon attack against that creature.
