NOTE:
-The Ultimate Recipe is in the old mansion. Go to the room where Goofy
and Donald slept in one of the pods in the under ground computer room. There
you will see beside a small chest, that's where you will see the ultimate
recipe.

- In the recipe its says that you need 13 orichalum+, don't bother
finding the 13 orichalum+ because there's only 7 orichalum+ in the game. So
only get all 7 orichalum+ for the Ultima Weapon.
