Reaper: Thanks, but i've saw that dig site, yet when i dig it nothing was there, well whatever.
About Orichalcon it's because it's kind of confusing, there's this other synthesis item called elemental sword or smth, that says it needs the orb of magic too, but i think the requirements are wrong, and no you can't make excalibur from the orb of magic and another item, the item would be elemental orb and i've already tried, they are just good items that can be ingredients for better items(and perphaps one of these better items can be part of the excalibur set?). Well, just make orichalcon if you feel like it, it won't be a problem.
