Kingdom Hearts 3D: Dream Drop Distance/The World That Never Was

Dive Boss: Queen Buzzerfly
In what should be his final dive, Sora faces off against Queen Buzzerfly. This Nightmare should be a breeze by this point. Dodge the attacks of its little helper bees (they will usually attempt to circle in on Sora with their stingers, but can also team up to create lasers that can act as a trap) and attack them once the targets deem them accessible. It only takes one attack to knock a bee out, so press repeatedly and Sora will move between the targets, taking out up to three bees in one go. Repeat the dodging process until all bees are knocked out, in which case you can move onto Buzzerfly. Attack its head until it turns around, revealing the vulnerable spheres on its back. Eventually, it will turn around and once again summon smaller bees, forcing Sora to repeat the process before he gets a shot at Buzzerfly again. Destroy all spheres on its back to complete the battle.

Main
Upon Sora's arrival, he is attacked by Xigbar, who subsequently explains what has really been going on for the entirety of the game. After this long series of cutscenes, Sora faces a mandatory drop, and the game will switch you back to Riku. Once you drop back to Sora, he'll face some puzzling mirages from his past. You start off in front of a Save Point and a Moogle Shop. Do whatever is necessary here before moving on. Follow the path into a group of some powerful Nightmares. Defeat them and continue to the dead end. Use Flowmotion to climb the building to the left, then turn back and jump onto the higher building. A chest at the edge of it contains a Dulcet Fantasy. Drop back down to the previous building and take note of the lower roof to the north. Jump across to it and use Flowmotion to climb the building directly to the left. It's a long climb, but at the top of it is a large chest containing Salvation. Drop back down and jump to an adjacent rooftop; at the edge of it is a Shield Cookie 3. Drop down past the chest to land on a staircase. At the top of it you should find a Water Barrel. From here, jump up so that Sora is directly in front of the building with the white marks on it. Enter Reality Shift and slash the chains at the bright white areas with the stylus. Follow the newly-cut up buildings upward, using any buildings with blue marks on them as catapults to the next, until you reach a building with a chest at the corner. Open it for a Savage Fantasy.

Drop back down to the ground and follow the mist to its source. In a large open area, a group of Nightmares should spawn. Take your time defeating them and open the large chest for a Drak Quack Recipe. Continue following the source of the mist by using Flowmotion to climb to the top of the building. Drop off the other side of it and take out the Nightmares. A chest to the right holds an Elixir. Press forward and continue to stay on the offensive with the Nightmares. A chest to the left holds a Dream Candy. Continue following the path right to enter a new area.

Contorted City
After the scene, open the chest up to the left for Block-it Chocolate 3. Move forward a bit and Sora will stop to observe the strange movements of the buildings. Head to the blue mark in the center and stay there until you're catapulted up to the building to the right. From here, move to the white-marked buildings that pop up. Use Reality Shift to slash them out of your way. Once that's done, some Nightmares will spawn, and as soon as they're taken out, even more Nightmares will spawn, until finally you can climb the steps to the left. At the top is Ars Arcanum. Continue forward, but stick to the left of the path to find an Elixir. Jump back onto the main path and, again, make use of Reality Shift.

Jump onto the slashed building and drop off to the right twice. Turn back the second time to find a chest containing a Shield Cookie 3. Use Flowmotion to ride the rail up ahead into a group of Nightmares. Continue on the path and some more Nightmares will spawn on higher ground. Jump up to the left for a chest containing Confetti Candy 3. Move forward and you should spot another rail to the right; ride it and you should see some Nightmares spawning in the far distance. The set of rails to the right are not only a good means of quick transportation to them but also makes the battle a bit easier by giving Sora the ability to heavily rely on Flowmotion attacks. If that isn't enough, linking with your Spirits is always an option in rough times. At the fork in the road, take whichever path you want. They both lead into a group of Nightmares, and a chest off to the right corner containing a Wondrous Fantasy. Use Flowmotion to climb up and continue forward.

Nightmares spawn continuously here, and as difficult as they may be as a group, it is recommended to stick around and defeat them all in preparation for Sora's final boss. At another fork, take the raised right path to an Ice Dream Cone 3. Continue forward into the Nightmarish Abyss.

Final Boss: Xemnas
Save and organize your deck appropriately before moving on to face Xemnas. Equip strong attacks aimed at a single target, such as the always-useful Sonic Blade and the recently acquired but equally as useful Ars Arcanum. You should also have a couple of Curaga spells in your deck. When facing off against one of Xehanort's forms, there is no such thing as too much caution.

The battle begins with Xemnas off to the other side of the map, throwing buildings at Sora. Dodging these is possible but a bit difficult; nevertheless, they don't deal too much damage, and you always have a break between buildings to cure if it becomes too much. Survive through this exchange and Xemnas will drop down to Sora's level, making him vulnerable to attacks but also giving him the ability to unleash a multitude of powerful attacks on his own. Xemnas is quick and unpredictable in his attack patterns. If you stray too far from him, he may either teleport to your location or dash toward you with a pair of glowing red swords. Getting caught in any one of his combos is an enormous risk, so dodge until he gives a pause. However brief it may be, this is an opening to unleash Sonic Blade, Ars Arcanum, a link attack with either one of or both of your spirits, or any other powerful attack which will get the job done.

Occasionally, Xemnas will form a box around Sora and shoot flares at the easy target. This is escapable by simply jumping out of the box, though you can form this into a Flowmotion attack by bouncing off the wall. Xemnas also has something of an instant KO in his arsenal, in the form of a circle of flares which he forms around Sora. Once you see this, jump up and dash away as far as you can get, as staying in his sights will only lead to certain death. A while into the battle, after you've knocked off enough of Xemnas' health, he'll halt the battle to toss buildings again. Dodge them and, from the force of one of Xemnas' buildings on Sora's floating platform, he will be catapulted into the air. All you can do here is trigger Reality Shift as soon as you see the pink target and slash the chains. While this isn't necessary, it will result in a great advantage, leaving Xemnas temporarily stunned and vulnerable to a barrage of attacks.

Defeat Xemnas to obtain two Glossary entries: Recusant's Sigil and Hearts Tied to Sora.

Riku
As soon as Riku lands in a world unknown to him, he immediately senses that something is up. Use the Moogle Shop to stock up on Curaga and any strong attacks you might need, though you should have plenty to choose from if you've been scouting out treasure chests, such as Ice Barrage and Shadow Breaker. Don't forget to save at the Save Point before moving forward. Open the chest on the ledge by the ramp for a Dream Candy and test out any new commands on the group of Nightmares. Up the ramp, a line of Nightmares will spawn in front of a large, spinning sphere. Attack it to gain access to Reality Shift, and slash the chains with your stylus to open up a path. Head down it to a room where a machine sporadically shoots lasers all over the place. Past it, to the north of the map, is a chest containing Curaga. Head down the path to the left.

Defeat the Nightmares and use Flowmotion to glide on the first pipe. To the right of it is a ledge with a chest containing Confetti Candy 3. Where the Nightmares spawn, use Flowmotion to climb up the wall to the east for a Keeba Tiger Recipe and an Elixir. Drop back down and continue down this path and open the chest by the wall at the end of it for another Elixir. Now walk into the beam of light and execute Reality Shift again. Drop down and open the chest for Doubleflight. Perform Reality Shift on the laser-shooting machine to finally destroy it. Head up the newly-formed path and, at the top, follow the path to the left. Some Nightmares will spawn along the way, along with a large group in the open room. Once they're done with, turn to the red wall with the moving ledges. Unfortunately, Flowmotion cannot be used to climb this wall, making the chests that much harder to obtain. Follow the ledges to the right up until you can jump up to an opening, where you'll find a chest containing an Elixir. There's also an opening to the left, with a chest containing a Dulcet Fantasy. You can use Flowmotion off the side of the ledges for easier access, especially for the opening in the middle, where a large chest holds Dark Splicer. Once done in this room, drop back down and return to the fork, going the opposite direction this time. Open the chest for a Dream Candy and exit to the next area.
