Would you ant to allow song of the heart, special instruments, or any inspire courage boosters to affect the troubadour's aura? Obviously it doesn't as written and I suspect that is intentional, though I could see perhaps allowing certain instruments to give a bonus (if you tie up a hand or hands to play, you are paying a mechanical price for the bonus as you aren't using those hands for fighting).

I can understand, fluff-wise, why the various abilities only apply to social skill uses, not the in-combat applications, but it seems that a buff to feinting wouldn't be over-powered or out of character for a troubador. I am not aware of any in-combat uses for diplomacy or gather information and intimidate isn't on the list, so it seems like a small boost for a niche combat option. Would it weight the class too heavily toward assassins and their sneak attack?
