Earworm
Wondrous item, legendary (requires attunement by a bard)
This powerful instrument once belonged to a legendary bard. They were single handedly responsible for saving the world from the forces of darkness. However, at the climax of the final battle, the bard’s body was consumed in a magical explosion that scattered the darkness. The only thing left behind was his beautifully carved rebec.
While you are attuned to Earworm, you gain a +3 bonus to your spell attack and spell save DC. In addition, if you miss with a spell that requires an attack roll, roll a d100. On a 91 or higher, you immediately regain the spell slot.
Earworm: The rebec also has a unique feature, when it is used against a creature that is concentrating on a spell. When the creature is successfully hit with a spell attack, their mind fills with the most annoying song. The creature must make a DC 15 Wisdom saving throw or fall prey to the earworm. On a failure, the creature has disadvantage on all concentration checks for the next minute.
