The Wild Ones Sick Jam

You sing or preform music to create a series of floating notes that fly towards a creature you can see within range. Alternatively you  can utter the name of a creature, if the creature named is within range they become the target even if they are unseen by you. The target must make a Intelligence saving throw, on a failure the target takes 6d6 psychic damage and has disadvantage on attacks rolls and saving throws until the start of your next turn. On a successful saving throw the target takes half damage and is otherwise unaffected.  If the spell is cast using a spell slot of 4th level or higher the damage is increases by 1d6 for every level above 3rd used.
