Here a couple more features I have been debating about including to enhance the flavor. What do you all think?


Furious Challenge
Starting at 6th / 14th level, whenever you are raging, you can let out a furious challenge that calls an opponent to arms as an action. Choose a creatures within 30 feet of you that can see and hear you. Each creature must make a Wisdom saving throw with a DC equal to 8 + your proficiency bonus + your Charisma modifier. One a failed save, any attacks that do not include you as a target are made with disadvantage and cannot willingly move away from you. This effect ends whenever you stop raging or if you willingly move more than 30 feet away from the target.


Words of the Victor
Starting at 10th level, you fighting prowess and reputation begins to give you an edge in diplomacy and negotiation. After you finish raging, you have advantage on all Charisma (Intimidation) and Charisma (Persuasion) checks you make until you complete a short or long rest.
