Bard's Lute

An instrument of the bards is an exquisite example of its kind, superior to an ordinary instrument in every way. It is commonly used among bards to cast their spells without exhausting spell slots

The spell, Strum, uses your spellcasting ability and spell save DC.

You can play the instrument while casting a spell that causes any of its targets to be charmed on a failed saving throw, thereby imposing disadvantage on the save. This effect applies only if the spell has a somatic or a material component.
