Synthesis Recipes

Item Synthesis is unlocked after Sora gains the ability to use the Green Trinity. Enter the Accessory Shop in Traverse Town and use the Green Trinity on the floor to drop a ladder that leads to the second floor.

At first only six recipes are available. The more recipes you successfully create (or MIX as the game says) the more will be unlocked.

Blazing Stone

EnemyChimeraLocationHalloween Town# Required7What you needNothing specific

Unfortunately, there is no quick place to land. Start from Guillotine Gate, and work your way through the level back to the Manor Ruins, where Sora fought Oogie Boogie. Drop down off the bridge to the ground below, where enemies immediately appear.

In order to see if the Chimera has spawned, look at the fence for the Red Trinity symbol. If you already have the item from this Trinity, but the symbol has reappeared, then the Chimera will spawn. If you have the treasure and the symbol is not there, you will need to leave and re-enter the Manor Ruins until it does.

You will have to defeat a handful of Wight Knights before the Chimera appears. Attack it normally until it jumps up onto a nearby boulder. The Chimera will summon four gargoyles, but they are fairly easy to defeat.

Several times throughout this fight, the Chimera will enter a phase where it shoots out colored orbs of light. You want to hit these back at the Chimera to earn some bonus experience, but they also increase the chance of extra Blazing Stones being dropped at the end of the fight. I can’t confirm it, but it appears as though having Aerora/ga active during this phase automatically sends the light orbs back.

Dark Matter

Dark Matter is one of the rarest synthesis items. 11 can be found in a handful of places, but the final three must be synthesized.

Energy Stone

EnemyStealth SoldierLocationHollow BastionItems Required6What you needStop

There are two rooms where Stealth Soldier can spawn: the Entrance, and the Grand Hall.


The best way to grind here is to warp to the Library and exit either of the doors to the Entrance. Approach the main fountain to spawn the initial wave of enemies. If you see 2 Wizards and 2 Large Bodies, leave and re-enter. If you see 2 Wizards and 1 Large Body, a Stealth Soldier has also spawned.

Once you defeat this wave of enemies, head up the staircase. Another Stealth Soldier will spawn with this group of enemies.

Finally, use the elevators to get to the second floor, and find a third and final Stealth Soldier here.

Grand Hall (Recommended)

Warp to the Castle Chapel, and head through the Lift Stop to get to the Grand Hall. The first group of enemies should spawn a Stealth Soldier in the second wave, alongside 2 Large Bodies. If you see 4 regular Soldiers, leave and re-enter to try again. Be careful, as this Steath Soldier tends to disappear once the Large Bodies are gone.

Head up the stairs to where Sora had his solo duel with Riku. Another 2 Stealth Soldiers will appear during wave 3.

Despite being invisible, Sora can lock-on to the Stealth Soldiers just like any other enemy. Dealing enough damage to them will temporarily dispel their invisibility, but the easiest way to fight them is to cast Stop. This effect lasts for an extremely short amount of time, but it is useful to get in close and deal some damage.

Lucid Shard

These are regularly dropped from Shadows, which can be found everywhere. This is best combined with searching farming Gigas Shadows. 19 Lucid Shards are required to make other items, but you need an additional 18 in order to craft two extra Dark Matters.

Power Stone

EnemySniperwildLocationTraverse Town# Required5What you needStopra/ga

Sniperwilds begin spawning as soon as the 2nd Visit to Traverse Town, but I recommend waiting until Stopra or Stopga is unlocked.

Fly to Traverse Town and land at the Accessory Shop. Leave through the door (or climb to the Synthesis Shop and leave from there) and move through the doors to the 2nd District. The Sniperwilds appear fairly regularly in the middle area in front of the fountain.

Initially, only one Sniperwild appears. After defeating it, two more appear. With those two taken out, three more of the Heartless will spawn in. This cycle repeats a total of five times before ending. Each time a Sniperwild is defeated, the experience is increased by 10p, and the chance for a Power Stone dropping is increased.

If Sora is seen by a Sniperwild, it will sound the alarm. At this point, more Sniperwilds will begin to spawn, making unavoidable ranged attacks at Sora. These Sniperwilds will not drop experience or items, so do not waste time fighting them. Exit via the nearest door, and come back to try again.

There is a very short window of time where Sora can attack and defeat the Sniperwild before the alarm goes off. While this is helpful, the best tactic is to wait for one of them to move away from the others and cast Stop. Sora should be more than able to deal enough damage to defeat the Sniperwild before Stop wears off.

Serenity Power

EnemyPink AgaricusLocationDeep Jungle, Tree HouseItems Required7What you needAerora/ga, Stopra/ga, a low Strength/high MP Keyblade

Equip a Keyblade with the lowest increase to Strength, and the highest increase to maximum MP. The best Keyblade for this is the Diamond Dust, which is awarded to Sora after completing the Gold Match at Olympus Coliseum. Additional accessories that raise MP, such as the Atlas Armlet and Cosmic Arts, are extremely useful.

If you haven’t unlocked the Diamond Dust yet, the Lady Luck is a decent substitute.

Fly to Deep Jungle, and land at the Jungle: Tunnel. Jump up the platforms and move through the Treetop and Climbing Trees to the Tree House. Upon entering the area, you are looking for a White Mushroom directly ahead on the path. If no White Mushroom is present, leave and re-enter the screen until they do. See the first picture below.

These White Mushrooms are slightly different in that they only want you to cast Stop. There are three White Mushrooms to cast Stop on, and the other two are hidden throughout the area.

Once all three White Mushrooms have been Stopped, the Pink Agaricus will spawn inside the Tree House. See the second picture below.

Do not engage the Pink Agaricus right away. Instead, cast Aero on Sora, then Stop on the Heartless. Lock-on to the Pink Agaricus, then attack the head. The goal here is to get as significant a hit combo as possible. Once Stop wears off, a hit counter will appear in the form of experience. The higher the combo, the better chance that the Pink Agaricus will drop a Serenity Power.

I have seen several people online recommend equipping the Ragnarok Ability for this fight, and using it to get even higher scores. In my experience, it didn’t trigger often enough to be worth it.

What you should see when you enter the Tree House. The Pink Agaricus inside the Tree House.

Stormy Stone

EnemyNeoshadowLocationEnd of the WorldItems Required4What you needAerora/ga

This enemy only appears in the final world, the End of the World, and is a rare enemy in the last area of the map. Aerora is sufficient, but Aeroga is better.

Fly to the End of the World, and choose to land at the Final Rest. Use the heart-shaped door to enter the Linked Worlds area. There are three potential enemy spawns here: a group of Invisibles and Angel Stars, several White Mushrooms, or eight Neoshadows.

The Neoshadows work similarly to the Gigas Shadows from Wonderland. As soon as they start to spawn, cast Aero on Sora. As stronger Shadows, they have the same annoying tactic, in that they can merge with the ground and avoid attacks. They teleport around a lot, and will occasionally burst out of the ground to grab at Sora’s feet.

With Aero up, attack the Neoshadows as normal. Aero will deal constant damage (assuming it is upgraded to Aerora or Aeroga), and protect Sora from damage. Only the final Neoshadow will drop an item, but the Stormy Stone has a significant drop chance assuming you defeat all eight.
