Ilia, I found a guide for you on Gamefaqs:
http://db.gamefaqs.com/console/psx/f...ics_relics.txt
It's by a guy named "Elmor the Elf", and is a pretty complete guide. You'll find info on all of the special items that aren't in stores, including how to get them: either by stealing, move-find-item, Secret hunt, etc. Good Luck, there are a LOT of special items!!

And, BG-57, I am going to try that Ninja/Mime throwing trick, it sounds plausible. Although, I'm wondering if the mime would just throw the original sword a second time and thus not make a duplicate.

P.S. Big Congratulations on completing the Lands/Treasures list!!!!!
