So I am working on the plans for an arcane archer for PFS and I am planning on going the bard route with the arcane duelist archetype. That would give him the arcane bond at level 5. The arcane bond says that you can add magical abilities to the item, but can you make it a specific magical item? For instance, this character would have a bonded longbow so could he make it into an Oathbow if he had the requisite fame and gold?
If there isn't some specific PFS ruling for named items, then you should be able to craft an Oathbow as your Arcane Bond in the same way you could create a +3 Longbow.
The description of Arcane Bond tells us that "adding additional magic abilities" is done as if you had the required item creation feat. And you can definitely craft an Oathbow if you had Craft Magic Arms and Armor.
