Your bow is not broken but you've run out of arrows. How can you fake being a bard?
Degolar is a Bard, so there is no need to fake it. But he's a multi-class Sorcerer and prestige class Sublime Chord, so he'd probably use spells over arrows. And he's a percussionist, which means he can make his music just by clapping his hands and stomping his feet and doesn't need tools when they're not at hand.
