While you aren’t wearing armor or wielding a Shield, you gain the following benefits.
Dance Virtuoso. You have Advantage on any Charisma (Performance) check you make that involves you dancing.
Unarmored Defense. Your base Armor Class equals 10 plus your Dexterity and Charisma modifiers.
Agile Strikes. When you expend a use of your Bardic Inspiration as part of an action, a Bonus Action, or a Reaction, you can make one Unarmed Strike as part of that action, Bonus Action, or Reaction.
Bardic Damage. You can use Dexterity instead of Strength for the attack rolls of your Unarmed Strikes. When you deal damage with an Unarmed Strike, you can deal Bludgeoning damage equal to a roll of your Bardic Inspiration die plus your Dexterity modifier, instead of the strike’s normal damage. This roll doesn’t expend the die.
