Starting at 3rd level, as a bonus action, you can attempt to charm a living (not Undead or Construct) intelligent (with an Intelligence score or at least 3) creature with 60 feet of you that can see you and that you can see. The target must succeed a Charisma saving throw or be charmed by you for 1 minute. While charmed this way, a creature thinks you're the most beautiful creature they have ever seen.
You can use this feature a number of times equal to your proficiency bonus. When you finish a short rest, you regain all expended uses.
Starting at 20th level, as an action you can set yourself ablaze with otherworldly beauty. If you do, all living (not Undead or Construct) creatures that can see you within 120 feet of you, except those you specifically exclude, must make a Charisma saving throw or be charmed for 1 minute.
While charmed in this way, a creature is incapacitated staring at you adoringly. The creature can reroll its saving throw at the end of each of its turn. The charm is automatically broken if the creature takes damage, it cannot see you at the end of its turn or if you fall unconscious.
You can use this feature a number of time equal to your Bard level divided by 10 rounded down. Once you finish a long rest, you regain all expended uses.
Starting at 20th level, your Mantle of Inspiration feature now gives your target a number of temporary hit points equal to your Bard level, and double their speed until the beginning of your next turn.
