This seemingly ordinary box contains one magical strumming pick. Holding this pick imbues you with the charisma of your favorite rocker. An apparition of them appears behind you and they strum a righteous tone that only you and your party can hear.  The pick then vanishes from your hand.

Notes: While holding this pick you may add your proficiency bonus to the end of any charisma check you make (this is in addition to whatever modifiers you already have). The Pick appears back in the box at dawn of the following day., BagOfHolding2025
