Just about every cool item in the game can be found in the Deep Dungeon. All "Move-Find Item" spots have two treasures that you can find, the normal item, like Phoenix Downs, and the rare items, like all of the cool equipment. The trick is to lower your character's brave(the one with Move-Find Item) real low, in the teens usually works for me. The lower the brave the better chance you have of finding the rare items. Be caueful not to lower it too low or you'll turn into a chicken. And to get a list of co-ordinates and items you can find, check out www.gamefaqs.com.
