Path of Battle Dancing

Not all rage comes from a place of hatred.  Some, like the rage of the followers of the god of wine and ecstasy, comes from a sense of twisted revelry.  An emotion like this is even more dangerous than the fury of your standard barbarian. because when rage and pleasure become entwined it becomes something that can no longer be reasoned with.

Bonus Profiency

When you choose this primal path at 3rd level, you gain proficiency in the Performance skill. If you are already proficient in it, you gain proficiency in one of the following skills of your choice: Animal Handling, Athletics, Intimidation or Survival.

Battle Anthem

Also at 3rd level, your rage is empowered by the spirits of savage music.  When you begin a rage, or as a bonus action while you are raging, you can activate your Battle Anthem.  Until your rage ends, the rage changes in the following ways:

• You gain temporary hit points equal to your Charisma modifier + your barbarian level.  These temporary hit points disappear when your rage ends.
• If you are not wearing armor, your Armor Class becomes 10+ your Dexterity modifier + your Charisma modifier.
• You add your Charisma modifier to Dexterity saving throws.
• You gain the deafened condition.  Music radiates out fro you, which can easily be heard by any creature within 300 feet.

Warrior's Tempo

At 6th level, if you are using your Strength score to attack with light or finesse weapons, you can forgo dealing the standard range damage and instead deal 1d4 thunder damage on every hit as powerful chords reverberate out of your weapon.  The damage increases to 1d6 thunder damage at 14th level.  Additionally, when you take the attack action while fighting with a weapon in both hands, you may attack an additional time on a turn that you use your bonus action to rage or activate your Battle Anthem.

Raucous Trance

At 10th level, you have advantage on Performance checks while raging.  Your rage doesn't end early from not taking damage or making an attack, so long as you use your action to make a Performance check.  You can extend the duration of your rage to 1 hour, so long as the only action you take is to perform.  If you take any other action, your rage ends.

Mosh!

At 14th level while your Battle Anthem is active, you can overwhelm creatures with the brutal beat.  As a bonus action you can force all creatures within 30 feet of you to make a Wisdom saving throw (DC8 + your proficiency bonus + Charisma modifier).  On a failure, the creature must use movement and take the attack action to attack an enemy creature on their turn, or use the dash action to get closer to an enemy if none are in reach.  Affected creatures have advantage on all attack rolls they make, but attacks against them have advantage until the start of your next turn.  A creature can choose to fail this saving throw.
