Bard class
As a bonus action, you can choose one creature other than yourself within 30 feet of you who can see and hear you. That creature gains a +1 bonus to hit on their next attack roll within the next minute. This bonus cannot be combined with a Bardic Inspiration die. If you give this bonus to another creature and the previous bonus is unused, the previous bonus expires. You can use this feature a number of times equal to your proficiency bonus and regain all expended uses after a long rest.
