It seems I am in possession of many finger bones. I will spare you their 'proper' anatomical names, as educating you in the structure of the hand is neither my purpose nor my job. However, as a Rogue yourself, perhaps you should study... yet—never mind. We are veering off-topic.
As I told you before, Don Julio managed to teach me his craft of the Bonescythe Armor, which I will provide to you—for a price. Should you come across anything resembling a ring while fighting, not only for your survival but for the rest of us, bring it to me. I will ensure it is adorned with these finger bones, which, in turn, will complete your set of armor.
