As I implied earlier, there is no weapon called the "Javelin II," just as there is no shield called the "Escutcheon II." To differentiate between the weak and strong versions of each item, some people have taken to qualifying the superior spear and shield with "II." Similarly, many people call the enhanced version of the Masamune (Grand Lion) in Chrono Trigger the "Masamune II." These designations are inaccurate, however, and confusing to someone in your position. To clarify, you will never find a "Javelin II" or "Javelin 2 (or Escutcheon II/2)," no matter how hard you try. You can find, however, a "Javelin" and an "Escutcheon" that are FAR more powerful than the normal versions of those pieces of equipment. Refer to my initial post for advice on how to obtain that weapon and that shield.
