A slender wand of dark ebony wood, capped with a silver tip on either end.
When you cast spells through this wand, it sounds as if you are conducting an invisible orchestra. You have full control over the melody, harmony, and timbre of the music. You can make the music audible between 30 and 300 feet.
While holding this wand, you can cast Thunderwave at will at a level equal to half your proficiency bonus (round up), and spells that deal thunder damage cast through this wand deal additional damage equal to your spellcasting modifier.
