Kingdom Hearts II Ultima Weapon

How the heck do I get Ultima Weapon??? I'm almost at the end of the game and I want to know how to get it

ps: I'm at Xigbar Battle

 

Beat Alantica fully, beat some cups at Underworld, beat 100 acre woods fully, and some other stuff I forgot.

 

you need to beat atlantica and 100 acre wood to get two orchum +'s. to get another one, beat the goddes of fate cup. you also need to get one of every item (ie, gem, crystal, stone, ect.) in the game and you'll get another. i forgot what else you need to do.

 

I tink you find one in a treasure chest in twilight town. Oh yeah, go to the place where Goofy and Donald were sleeping then get the treasure chest, inside will be the recipe.

 

I'll PM you the list of ingredients. :)

 

It's impossable for you at the moment (unless you're in FM+ and talking about data Xiggy) because one of the orchialcum+ s is from beating the Goddes of Fate cupunlocked when you beat Xemnas at the Alter of Naught. Also keep in mind that the recipe says 13 but the game has 7. That's because you need to use an energy crystal to cut the price in half.

 

um... I guess I'll just start a new file and do watever I need to do, since its impossible. *starts playstation*

 

Just beat Xigibar and Xemnas *first fight* and you can do everything that the above post have made.

 

There's no need for that, just advance a little bit further in the game.
