You may need an extra item or so. Just check to make sure that you do.
If you got an item earlier in the game without having the recipe of ultimate weapon
you might have sold an item which you can not get again.
such as a mythril crystal or oriculam + or oriculam.
Maybe that is what happened.
or you forgot to get the recipe.
The Mythril Gem recipe isn't something you can find in the game Kingdom Hearts 2. It is automatically unlocked when you reach Moogle Synthesis level 8 under Free Development. To level up your Moogle Synthesis, create different items and using Bright materials (like Bright Shard, Bright Stone, Bright Gem, and Bright Crystal) will double the EXP when creating an item.
To unlock Sora's ultimate weapon, the Ultima Weapon, in Kingdom Hearts II, you need to collect all the synthesis materials. Specifically, you must gather 13 different synthesis materials, including the "Orichalcum" items, which are found in various locations, such as treasure chests and by defeating certain enemies. Additionally, you need to complete all synthesis recipes at the Moogle shop. Once you've gathered the necessary materials, you can synthesize the Ultima Weapon.
First, you have to get the Ultima Weapon recipe from the basement on the way to the room where Sora wakes up after Roxas finds him, then take it to a moogle. You have to have given the moogle every kind of material and have all the ingredients for the weapon. Also, you need the ingredient that halves the amount of an ingredient needed, so you can have all the orichalcum+ ( i think its orichalcum+)
Amateur Moogle - Recipe and Free Development items can be created.Novice Moogle - Brightness or Energy Materials can be used in recipes.Junior Moogle - Serenity Materials can be used.Skilled Moogle - Two kinds of special materials can be selected at a time.Senior Moogle - Rank C items are at half-cost.Artisan Moogle - Rank B items are at half-cost.Master Moogle - Rank A items are at half-cost.Superior Moogle - The strongest items in Free Development are unlocked.Primo Moogle - Rank S items are at half-cost.
you need to get the 7 orichalcum+s, and all the other ingredients and some bright or energy shards. you need to get the ultimate recipe you can't buy it you find it at where Donald and goofy were sleeping when you found them as Roxas but know you have to find the pods Donald and goofy were sleeping in as Sora
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!

well first of all its called orichalcum. these you can easily get from the vending machine heartless. there's one at beasts castle in the west wing. Orichalcum +'s on the other hand are hidden in chests in various worlds. if you are trying to synthezize the ultimate weapon (a very nice keyblade i might add) it says you need 13. however, if you lvl up your moogle enough, you only need 7. trust me I've done it.
Itd best to save those until you make the ultimate weapon but there are 6 you can find and you get one when you obtain all synthesis material types
This depends on whether you have KH or KH2. If you have KH2, you must get all the crystals, an Orachilum, and all 13 Orachilum+, and the Ultima Recipie. Then go to a Moogle and Synthisize. In KH1, you need 5 lucid Gems, 5 Thunder Gems, 5 Power Gems, 3 Mystery Goo and 3 Gale.
with the key to rewards and the moogle shop
In all of the armored cores, I'd say Armored core V is the best because aside from its amazing mech customization its weapons are also update and there is another genre of weapons called Ultimate Weapon. Although Ultimate Weapon can only be used once it can have devastating damage or effects to your enemies.
