Drop the Bass

With the scream of a power chord, two fiery portals open within 60 feet of the caster, summoning two speakers the size of the caster. The speakers have a fly speed of 30 feet and can hover. The speakers give advantage on any Performance check (electric guitar) and allows the caster to add their proficiency bonus to any Persuasion or charmed attempt using the guitar as a medium. Alternatively, the speakers allow the caster to send out 15 feet cones of sound with their vicious licks to deal 1d8 thunder damage to an enemy.
