synthesize minor items till you are able to cut the ingrediants in half furthermore you want to level it up all the way so S rank items are cut in half so thats 14 to 7
then the second cut to 4 and that is easy! just get chest from twilight finish 100 wood finish atlantica (might be a problem) by the time you get to max moogle level you get another orachlum+ from having at least 1 of each item! this is the fastest and best thing I could come up with. use luck luky with ability weapon and equipment with all party members to synthesis quicker

In that video, the person obtained the Ultimate Weapon by using a cheat device, most likely Gameshark, AR Max, or COdebreakers, because all the Orichalcum+ cannot be obtained until after that battle takes place

There is multiple stickied threads in this section that can assist you in creating the Ultimate Weapon, you can look at them to figure out how to get it, and obtain all the ingrediants necessary for it
