After you proceed out of the Crystal Cavern, you proceed back into the Dark Valley, continuing to explore Radiant Garden. Continue fighting Heartless in the Garden Perimeter and the Bailey. Once you make your way into Town Plaza, pass Merlin’s House and arrive at the Marketplace.
Once there, Scrooge McDuck and Ludwig Von Drake are carefully surveying the area, while the Moogles are doing their own thing. You approach the Moogles, who look like they’ve got something up their sleeves. It appears they want your help with something. Now’s your chance to decide whether you want to follow through with their task. Choose very carefully. They are so happy that you’ve agreed and lead the team to a certain destination.
They head towards the Dark Valleyand lead them down the large open valley. Now, they have a little trick up their sleeves. They lead them up to a large canyon wall, where they use their Synthesis magic to make the material of the wall disappear, revealing a dark cavern. Brace yourself now, once you go in, you many not come out…The team continues into the Cavern of the Unknown: Entrance.
In the entrance area, there’s a lonesome save point in the dark cavern. After saving your game, which is a must-do, continue into the Cavern of the Unknown. Once inside, the entire area is pitch black, so you’ll have to use the map or the Auraga spell to light up the near surrounding area. However, at several points, large cliffs or boulders will block your path, without you even knowing it, so use the Aura spell every now and then.
To make matters worse, some of the most strongest Heartless that we’ve seen reappear in this cavern, traveling in the darkness, making the fighting even harder. It’d be best if you leveled up sufficiently in the game by this part of the game, even level up in the cavern because the upcoming fight IS the hardest battle in the game. So, brace yourself and get ready for the fight of your life. You should probably level up to level 99 just for the heck of it. You’d be surprised, leveling up happens much quicker in this cavern.
A mysterious noise lies ahead.
The team goes into investigate the noise and…uh-oh. A huge monster attacks. WHY WOULD THOSE CUTE, CUDDLY MOOGLES BRING US HERE!?!?
-Boss: Ultima Weapon-
This ultimate boss finally makes its way into the Kingdom Hearts series, after appearing throughout several of the Final Fantasy games, such as Final Fantasy VII and Final Fantasy X. This monster is the fiercest monster in the game, so make sure you’re at an exceptionally high level, have you’re best armor and items equipped and have the most powerful Keyblade in the game, thus far. In this area, thankfully, there are flamed torches along the wall, so you don’t have to fight the monster in the dark. Little consolation. This monster doesn’t need the darkness to destroy you.
This monster takes up a large space of the cavernous room, however, since its so big, it makes it difficult for the creature to move. You have to attack the creature’s head, so Glide and High Jump is a must for this battle. The worst part of the battle, Ultima Weapon has two invisible health bars that have to be fully destroyed before any actual damage is taken. The monster is slower than most, but it’s attack can reduce your HP by thirds, so be careful and aware of your surroundings.
He’ll attack with his claws, his jaws, as well as its wild flapping wings. The true difficulty of this battle, as with most, is trying to attack the creature without getting damaged. Four hits and you’re a goner in this battle, so you’ve got to control this battle very carefully. There’s always a certain amount of luck with winning this battle, so let’s hope the fates are on your side.
Then, Ultima Weapon will start casting a spell called Ultima, one of the strongest spells in the Kingdom Hearts Universe. This attacks casts a fleet of green mist about the area, as a large bean of energy is about to head straight for Sora. However, the attack can be dodged at the last second, when Weapon throws the beam of energy at the team. Head right for Weapon to dodge the attack. Continue the fight until Weapon falls, helplessly, to the ground.
Ultima Weapon disappears, as the cavern becomes flooded with light, revealing a Synthesis Chamber. It turns out that the Moogles have been trying to rid the Cavern of Synthesis from that haunting monster for years. Crystalline gems and diamonds line the walls, as they reflect light across the room. They explain that they are going to use this Synthesis Chamber as a way to continue their business and fund the future construction of Radiant Garden.
They couldn’t solve their problem by themselves, so they enlisted the team to help them, and they successfully accomplished that goal. They could come into the chamber anytime they’d like to receive discounted items and of course, synthesize their items. Before the team leaves, the Moogles call out to them and hand Sora the Ultima Weapon Keyblade, the ultimate weapon of the game, for defeating the ultimate boss.
Sora obtains the Moogle Army Summon. That’s right! This cute flock of small synthesis creatures may seem all but violent to the common eye, but put them in the midst of a few Heartless and they form a wall of destructive force, taking down any that lie in their path! Yes.
Sora, Donald and Goofy return to the Gummi Ship.
