The College of the Opera archetype for the Bard class is everything a subclass should be. It is flavorful, concise, it adds something missing from the core system, and doesn't break the game with its new mechanics. I love it.
The voice is clearly an instrument that was ignored by the core PHB. With this sub-class it is now also a potent weapon! I hope you enjoy this sublcass as much as I have.
