How to get all 7 Orichalcum+ to synthesize the Ultima Weapon (Kingdom Hearts 3)

There are a total of 7 Orichalcum+ in Kingdom Hearts 3, and you will want to collect all 7 of them if you want to get your hands on the best Keyblade you can get; the Ultima Weapon. Not only do you get the best keyblade when you craft the Ultima Weapon, you also get an achievement or a trophy depending on your console, so it's a great thing to get for those of you who are interested in that.

Anyway, it takes all 7 Orichalcum+ to be able to craft the Ultima Weapon, and you will learn how to get all of them in this guide. Keep in mind that these are unique materials, so you can only get each of it once, and you cannot choose one of the 7 and farm that repeatedly.

Also make sure not to confuse Orichalcum with Orichalcum+; the plus version is a lot rarer than the regular one. You can obtain the Orichalcum+ in any order you like, so feel free to not follow the same order as below.

Anyway, let's get on with the guide.

Orichalcum+ #1: Loot the treasure chest in The Final World.

You unlock The Final World after you complete the main story in the game. This World is not that exciting, but it has a single chest in the middle of it. Loot this to get the Orichalcum+ that is found within in. 

You will be taken directly to The Final World after you complete the main game, but you can also return at a later time by going to the Badlands checkpoint in the Keyblade Graveyard World and enter the red battlegate located there.  

Orichalcum+ #2: Complete the 7 Flans.

There are 7 Flans called the Fantastic Seven in Kingdom Hearts 3, and each of these Flans will give you a challenge when you find them. You will need to complete the challenge with a score that gives you all 3 fruits as a reward, for all 7 Flans. Once you get 3 Fruits in all 7 challenges, you will get a Orichalcum+ for your effort.

Orichalcum+ #3: Defeat the Omega Space Ship. 

The Omega Space Ship is a Gummi Ship boss that you can access from The Eclipse Galaxy. Start by defeating all the hostile space ships in the outside section of the galaxy, which forces the Omega Machine to spawn on top of the central structure. You must then defeat this boss with your Gummi Ship to get the Orichalcum+.

Orichalcum+ #4: Get it from a Moogle Shop postcard. 

When you buy a lot of items in the Moogle Shop, you will often get a postcard that is sent to you in the mailbox in Twilight Town. So check this mailbox for a postcard that include a cool reward.

You have a small chance to get the Orichalcum+ every time you open a postcard, and this is all randomness and no strategy. You essentially have two options:

1) Keep buying stuff and cross your fingers that you eventually get the Orichalcum+.

2) Buy enough items to get a postcard, then save your game file. Now check the reward, and reload if it's not the Orichalcum+, since the reward is determined when you open the mailbox. Just keep doing this until you get the Orichalcum+. This can take a while, but it's a much cheaper way to do it!

Orichalcum+ #5: From the Frozen Slider minigame. 

You can play a Frozen Slider minigamme in Arendelle after you have beaten the world for the first time. Travel to the Mountain Ridge checkpoint be able to replay the minigame. You must collect all 10 diamonds in the mini game as well as finish it to get the Orichalcum+ as a reward.

This might sound very difficult, but the good news is that you won't have to collect all ten diamonds in a single run. So keep doing it until you get all ten of them.

If you don't get the reward upon finishing the run with the last diamond, do another run, because some players have reported not getting it until doing that.

Orichalcum+ #6: Collect 80 Lucky Emblems. 

There are a total of 90 Lucky Emblems in Kingdom Hearts 3, and you need to collect at least 80 of these if you want the Ultima Weapon. Once you get 80, you are awarded with an Orichalcum+.

You probably have some of these already, but if not, look for Micky Mouse icons scattered around in the Worlds. We recommend using a guide if you haven't already found 80 randomly.

Orichalcum+ #7: Find it in a treasure chest in The Caribbean.

There is a treasure chest that contains an Orichalcum+ on Exile Island in the Caribbean. Just fast travel to the island by looking for the big X on the world map. Go to the middle of the island and open up the treasure chest there, and you're good to go! That's the last Orichalcum+, and you're all done.

Crafting the Ultima Weapon

Now that you have all 7 Orichalcum+, you will definitely want to craft the best Keyblade in the game, Ultima Weapon. You get the recipe when you have collected all 58 different synthesis materials in the game, and crafting it requires the following:
- 7x Orichalcum+.
- 2x Wellspring Crystal
- 2x Lucid Crystal
- 2x Pulsing Crystal

Now just synthesize the Ultima Weapon from a Moogle Shop, and you are ready to keep playing with the very best keyblade you can get!
