Bardic Inspiration

The Zenithbard can inspire others through stirring words or music. To do so, they can use a bonus action on their turn to choose one creature other than themself within 60 feet of you who can hear you. That creature gains one Bardic Inspiration die, a d12.

Once within the next 10 minutes, the creature can roll the die and add the number rolled to one ability check, attack roll, or saving throw it makes. The creature can wait until after it rolls the d20 before deciding to use the Bardic Inspiration die, but must decide before the DM says whether the roll succeeds or fails. Once the Bardic Inspiration die is rolled, it is lost. A creature can have only one Bardic Inspiration die at a time.

The Zenithbard can use this feature 12 times. They regain any expended uses when they finish a long rest.

The zenithbard can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The zenithbard regains spent legendary actions at the start of its turn.
