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.
At Higher Levels: Your Bardic Inspiration die changes when you reach certain Bard levels. The die becomes a d8 at level 5, a d10 at level 10, and a d12 at level 15.
