How to Craft Memory Fragments

Inside a Character's Memory Fragments or Storage

Chaos Zero Nightmare - Storage Craft
You can access crafting by going to any character's memory fragment page where the button to navigate to crafting is located on the bottom left of the screen or inside the storage.

Use Traces of Memory to Craft Memory Fragments

Effect Cost
Craft a random part of a specific Memory Fragment Set
Craft a chosen part of a specific Memory Fragment Set
Craft a chosen part with a selected main stat of a specific Memory Fragment Set

When crafting a memory fragment, it costs Traces of Memory to make one. Cost increaes based on how much you want to control the randomization of how you're memory fragment will turn out with the best one where you can choose what part it is and specify what main stat it will contain at the cost of 1 Multidimensional Alignment Material.

However, you cannot choose what substat a memory fragment will get after crafting and will always be randomized.

What Are Memory Fragments?

Equipment Set with Bonus Effects

Memory Fragments Equipped
Memory Fragments are equipment sets exclusive to combatants that provide various stat bonuses when equipped. Each set contains 6 types of Memory Fragment pieces and equipping a combination of the set can activate Set Effects based on the required number of pieces. Since you have 6 slots in total, you can also mix pieces from different sets to gain multiple bonus effects.

Upgrading Memory Fragments

Upgrading Memory Fragment
Each Memory Fragment piece can be upgraded to further enhance its stat bonuses. Upgrading a piece may roll a new stat, randomly selected from a pool of possible stats. These Memory Fragments have both a main stat and substats. the main stat gains the largest boost from upgrades, while the substats are randomly determined from the available pool.

Memory Fragments Upgrade Mechanics

Rarity Max Level No. of Substats to Unlock
Legendary 5 1
Rare 4 2
Uncommon 3 3

Legendary Memory Fragments, which you’ll start obtaining at Difficulty 5 and above, already have three substats unlocked. You can upgrade them up to level 5. The first upgrade unlocks the fourth substat, and each subsequent upgrade increases the value of one of the existing substats. Do note that each upgrade, regardless of rarity, also increases the value of the Memory Fragment’s main stat.

Rare Memory Fragments start with two substats, and upgrading them twice unlocks the remaining two. However, since they can only be upgraded to level 4, you’ll have only two additional opportunities to increase their substat values. Uncommon Memory Fragments can only be upgraded to level 3 and start with one substat, which means that upgrading them to their max level will unlock all remaining substats without giving you any chance to increase the value of an existing substat.
