As a Bonus Action you can inspire another creature within 60 feet of yourself who can see or hear you. That creature gains one of your Bardic Inspiration dice.
A creature can have only one Bardic Inspiration die at a time.
Once within the next hour when the creature fails a D20 Test, the creature can roll the Bardic Inspiration die and add the number rolled to the d20, potentially turning the failure into a success.
A Bardic Inspiration die is expended when it's rolled.
Number of Uses - You can confer a Bardic Inspiration die a number of times equal to your Charisma modifier (minimum of once), and you regain all expended uses when you finish a Long Rest.
The Bardic Inspoiration die is a d6 at level 1, d8 at level 5, a d10 at level 10, and a d12 at level 15.
You now regain all your expended uses of Bardic Inspiration when you finish a Short or Long Rest. In addition, you can expend a spell slot (no action required) to regain one expended use of Bardic Inspiration.
You can use musical notes or words of power to disrupt mind-influencing effects. If you or a creature within 30 feet of you fails a saving throw against an effect that applies the Charmed or Frightened condition, you can take a Reaction to cause the save to be rerolled, and the new roll has Advantage.
