In-game Explanation for Arrows

[Anonymoose]

So probably a really big and really sharp broad head arrow that causes a big flesh wound?

I reckon.

As for the broader topic of the thread at large, I once imagined that we'd be able to swap out quivers for extra effects, but the skills themselves seem to allow us to do that on their own just fine. I like to imagine that, as Andaeron said, we just don't see people refilling their quivers every now and again (the same way we don't see them hit the outhouse or apply ointment to the various rashes that I assume are prevalent in Eorzea). Likewise I imagine that the archer/bard in question has a few types of arrows in the quiver and a few phials of applicants that we just don't see made discrete.
