Rhythm Maker's Drum +1

Uncommon

While holding this drum, you gain a +1 bonus to spell attack rolls and to the saving throw DCs of your bard spells. As an action, you can play the drum to regain one use of your Bardic Inspiration feature. This property of the drum can't be used again until the next dawn. If you have proficiency with a given musical instrument, you can add your proficiency bonus to any ability checks you make to play music with the instrument. A bard can use a musical instrument as a spellcasting focus, substituting it for any material component that does not list a cost. Each type of musical instrument requires a separate proficiency.
