Go to the mansion in Twilight Town and go to the room where Donald and Goofy were sleeping in their pods when you were playing as Roxas at the beginning of the game. You can find it next to Donald's pod. Once you have it, go to a Moogle Shop and you can synthesize the weapon.
You need to collect all the synthesis materials necesary and also the recipe.
utima weapon you mean you just kep mixing thing at cid's top floor and you will see it
You have to mix all the items, then you would get the Ultima Weapon recipe.
In Kingdom Hearts 2 there are 2 kinds of "Special" Keyblades. The first kind is the Ultima weapon which is a Synthesis item. The recipe can be found in the Mansion at Twilight Town. The second is the Fenrir Keyblade. This Keyblade is obtained after defeating Sephiroth in Hollow Bastion or Radient Gardens. He can be found past the spot called "Crystal Fissure"
You have to mix all of the items and then you'll get the Ultima Weapon recipe.
mate there is no recipe just make everything then you will see it on the list
You'll have to mix all the items then you'll get the Ultima Weapon recipe.
this is not my answer i fount it You must get the Ultima Recipe in the basement of the mansion in Twilight Town. After this, you'll be able to use the Moogle Shops to synthesize the keychain
You need the ultima recipe from the mansion in twilight town. Once you have it, collect all the necessary ingredients and synthesize them with a moogle.
you always start with same key blade but to get max stats at start pick shield and destroy sword
You can get its recipe about the end of the game. When you go to twilight town to the old mansion where you fix the computer enter Roxases town (just go through the portal) and from there go to the place where you fought Axel with Roxas. From there go to the room where those pads are and between Goofys and Donalds pad there is the Ultima recipe. But its actually hard to make because you'll need 7 Orachilum+ -_-" Well good luck anyway :)
First if you havent figured it out already you first have to find the ultimate weapon recipe and your moogle lvl has to be high then you need 8 orichulum+'s im not sure what else but if you find the recipe and moogle you'll know and 1 little secret you can get orichulum+'s from those candy machines that are random events. Hope this helps!
