Welcome, this guide is going to be very extensive and detailed so be ready for some reading. Also, there is a video to follow if you wish to go that route which will show more detailed gameplay on the points that I make here.

If you're a new player to the Kingdom Hearts franchise than you'll probably be wondering what the Ultima Weapon is. Well, in every Kingdom Hearts since 2003, it has been the ULTIMATE endgame weapon that provides a massive strength and magic boost over every other keyblade. Kingdom Hearts 3 follows the same route that Kingdom Hearts 1 and Kingdom Hearts 2 did by requiring that you farm for specific materials to craft it, except it is much easier this time around.

Step 1: Unlock The Recipe
There are a few hoops that you need to jump through to even get its recipe which will require you to find and return 58 different Synthesis items to the shop moogle. This might sound a little daunting at first but it will only take you a few hours since you need only 1 of each item.

NOTE - You should only go for this weapon after you complete the main story of the game so battle portals can spawn. Be sure to consult your Adversaries section of your Gummiphone.

Sinister Shard, Stone, Gem & Crystal - Door Vault Service Area (Turtle Toads) (Monstropolis)
Note: You should kill the 4 toads in this area just before the elevator save point then teleport away and teleport back.

Soothing Shard, Stone, Gem & Crystal - Battle Portal 10 (The Carribean)

Wellspring Shard, Stone and Gem - Battle Portal 10 (The Carribean)

Hungry Crystal - Battle Portal 12 (San Fransokyo)

Orichalcum - World Chests and The Eclipses Asteroids
Electrum - The Eclipses Asteroids and Blue Crystals
Evanescent Crystal - 1-time reward from Battle Gates
Illusory Crystal - 2-time reward from Battle Gates

Step 2: Find 7 Orichalcum+
This will be a much simpler task than step one was so for this one, you can either watch the video below (Incoming) or you can read this guide.

#1 - After you have returned from the Final World, you can return to it by interacting with the pink crystal in the keyblade graveyard. When you get here, open the chest for the item.

#2 - Found inside a chest in The Carribean on Exile Island.

#3 - Get the high score for each of the Flantastic Seven for the Orichalcum+. Generally, you want to aim for 5-10,000 points over the 20,000 marks each time. You'll know if you've succeeded because you'll be given 3 Fruits, a skill and the Flan will bounce up and down.

#4 - You must find 80 of the 90 lucky emblems. Follow my guide over at the Hidden Kings achievement for videos on all worlds lucky emblems.

#5 - Collect all 10 treasures on the Frozen Slider mini-game which can be started by speaking with Goofy at Elsa's Palace. You'll basically need to take all 10 different paths in the level, requiring up to at least 9 runs.
{Video Guide Incoming}

#6 - Simply buy enough items from the Moogle Post Shop in Twilight Town and you'll get a postcard. Save your game first then post the card in the mailbox for an item. If it's not an orichalcum+ you should reload the save and try again.

#7 - Kill the secret Eclipse Galaxy Boss. You can make this boss spawn to fight you by killing the 3 enemies around the ship you come out of and the one underneath the ship. Head up to the top and fight a big pink boss and it will drop it.
