Arcane Band

You call forth a spectral band of your choosing within the radius of the spell focusing on the caster as the center of the spell. While within that radius you gain advantage on performance checks during the duration of the spell. If the caster leaves the radius the spell ends. The arcane band can not make their own instruments therefore any you carry on your person are used for the band members. When the spell ends they will return the items to your storage. They are intangible to attacks and cannot attack themselves. When casting at a higher level for every additional level above 1 double the radius of effect to summon more band members. They only respond to the casters will and their instrument.
