Proof of the bow

Although this map doesn't look like anything important, it actually hides a big secret. It shows the location of an item that is very meaningful to us archers. What item is it? It is the Proof of Bow, an item that is passed down and when the truly exceptional archers have it, it shines. Since there is no record of it ever having been used, it seems like it only has a symbolic meaning. Whatever the truth may be, as long as one has this, wouldn't it at least be proof that you are a first-class archer? That is why I really want to have it. Fortunately, the approximate location is indicated on this map. I am hoping that you'll find it for me because I cannot leave this place. Please find Proof of Bow at the Expedition Camp Site. I ask you to do this.

This is the Proof of Bow. I cannot definitively feel a special power, therefore it seems that possess nothing except symbolic meaning. Still, there should be a definite difference between having this and not having it. Ah, I should write a thank-you letter to Reduros.
