When you make a Charisma (Performance) check, you can treat any roll lower than your bard level as your bard level.
When you use your Inspiration feature, you can grant your Inspiration Die to two creatures, instead of only one, or three creatures as a level 14 bard.
When you cast a level 1 bard spell or higher, you can expend one use of your Inspiration feature to grant your Inspiration Die to each target of the spell, to a maximum number of targets equal to your Charisma modifier.
When a creature adds your Inspiration Die to a d20 test and the roll fails, you regain one expended use of your Inspiration feature.
When a creature rolls your Inspiration Die, you can grant an Inspiration Die to a friendly creature within 30 feet of it, provided the creature can hear you.
A creature that adds your Inspiration Die to a saving throw against an enchantment or illusion spell or magical effect also has advantage on the save.
