Music buff skill...

To fully train Playing Instrument, I need to learn a music buff skill. The problem is to learn music buff skills, I need to learn Playing Instrument first! Has anyone who has Playing Instrument novice fully trained theirs?

You don't need to use music buff skills to complete rank Novice. Just play any default song and you can advance it.

Thanks, I just advanced it without fully training.

O-o Why the hell is it a requirement for Novice when you actually can't learn one at that point?

Because Nexon is good at what they do.
