In order to create the Custer Cuffs, you will need to morph the Arc en Ciel recipe with an Adamant.
Here are the other requirements you will need to meet:
- Synthesize the Ravage Hammer: You will need a hammer with Gathering Rank 3 to collect Adamant.
- Synthesize a Golden Axe: You will also need a Rainbow Gemstone, which requires an axe with Gathering Rank 3.
- Synthesize at least 10 Grand Orgen ingots: You will need to add Grand Orgen ingots to the Cluster Cuffs in order to stack up stats.
Obtaining the Ingredients
For this recipe, you will need a Rainbow Gemstone and Adamant. Both ingredients can be obtained from the same gathering nodes in the Underworld Orim region, simply by switching your tools around.
Rainbow Gemstone and Adamant
Fast travel to Holy Site of Urdis – Great Tree of Urdis. This area is located to the northwest of Windle.
Use the Golden Axe on the boulders around the area to obtain the Rainbow Gemstone.

Switch over to the Ravage Hammer and use it on the same boulders to obtain Adamant.

Synthesizing the Cluster Cuffs
After collecting the necessary ingredients, head back to the Atelier.
Select the Arc en Ciel recipe. Start by adding a Rainbow Gemstone in the Effect 1 loop.

Insert a Magical-category ingredient in the Effect 3 loop, which requires Ice Element level 3.

Continue to the loops on the left side. Add a Magical-category ingredient to the Quality loop, which has an Ice Element level 2 requirement.
You can use an ingredient with Effect Spread in this loop and skip the next three, which require some relatively rare ingredients. This will also allow you to add a few more Grand Orgen ingots in the final step.
However, if you do not have an ingredient with Effect Spread yet, continue along the synthesis flow.

Insert a Neutralizer-category ingredient in the Traits loop, which requires Fire Element level 3.

Add a Gold Puniball to the second Quality loop.
Gold Puniballs can only be obtained from Gold Punis in the Abandoned Village and Old Mansion areas. However, Gold Punis will only spawn if you use a Secret Key with the “Appearance of Rare Monsters” effect.

Insert a Gold Puniball in the Effect 2 loop, which has a Bolt Element level 4 requirement.

Add a Rainbow Gemstone to the second Effect 2 loop.

Insert the Adamant in the Recipe loop to complete the morph. This loop requires Ice Element level 5.

Do not synthesize the recipe yet.
Continue to the Effect 2 loop in the Cluster Cuffs recipe. Use all the remaining ingredients to add as many Grand Orgen ingots as possible.

You can now synthesize the recipe, and then add all effects later via Item Rebuild.

In order to rebuild the Cluster Cuffs with all effects, you will need the following ingredients:
- Two Grand Orgen ingots (Air Element level 4, Fire Element level 3).
- Nine Elixir-category ingredients (Air Element level 4, Bolt Element levels 3, 5, 6, 10; Fire Element levels 2, 4, and 5).
- Seven Miscellaneous-category ingredients (Air Element levels 4 and 8; Bolt Element levels 3 and 6; Ice Element level 4).
- Three Arc en Ciel units (Air Element levels 3 and 4).
You can easily fill out all loops with Philosopher’s Stones and the Arc en Ciel’s own Effect Spread.
Once all loops are maxed out, the Cluster Cuffs will have these effects:
- United Chain: raises the Tactics Level faster and boosts Fatal Drive’s damage.
- Cue for Cooperation: reduces the cooldown for Switch Skills, Order Skills grant additional AP.
- Pole of Force: increases skill damage and boosts the duration of Key Modification effects.
- Extreme Point Technique: reduces the wait time for skills and increases the success rate for Secret Key creation.

You can also use the furnace to further improve the Cluster Cuffs by adding Traits, Super Traits, and by boosting its stats up to the maximum of 999.
