Build-Your-Own Guide, Not a Copied Tier List
Other sites publish a single "best build" per combatant — that's someone else's opinion, and we're not copying it. Instead, this page explains what each piece of a build actually is and does, then shows you how to reason your way to a Memory Fragment set choice using your combatant's Attribute and the set's own effect text.
Start with the 6 pieces below to understand what you're assembling. Then use the Attribute table to see which Memory Fragment sets explicitly boost your combatant's damage type — every match is backed by a quote from the set's own effect, not a guess. Class-based gear advice is intentionally left out; see why in that section.
The 6 Pieces of a Build
A finished build combines six separate systems. Tap any card to open that system's own page.
Every combatant fights with a deck of cards — the core of combat. Card pool, rarity and how to browse them all live on the Cards page.
A companion unit collected separately from combatants that supports whoever you attach it to. Compare options on the Partners list.
The base gear system — 3 slots, dropped directly in Chaos, deterministic stats by star rank and rarity. Full mechanics are on the Equipment page.
The second gear system — 6 slots, farmed via Simulation or crafted, with 2-piece/4-piece set bonuses. Sub-stat ranges and a score calculator live on the Memory Fragment Scorer.
A card-upgrade mechanic that strengthens an existing card in your deck rather than adding a new one. See the full term in the Glossary.
An effect layer tied to Persona Cards and season-limited equipment. We've only confirmed a partial picture of how it works — see the Glossary entry for what's verified so far.
Picking a Memory Fragment Set by Attribute
Every combatant carries exactly one of 5 Attributes. Some Memory Fragment set bonuses explicitly boost damage of one Attribute — we only list a set here when its own effect text names that Attribute outright, not because the set's name sounds related.
| Attribute | Matching sets | Why (quoted from the set's own effect) |
|---|---|---|
Passion
|
Spark of Passion Prelude to a Hero |
Spark of Passion: 4-piece: after upgrading a card 5 times, Passion damage rises 20%.
Prelude to a Hero: 4-piece: discarding a Passion or Void Attack card grants +15% Crit Chance for 1 turn (caps at 15%).
|
Void
|
Offering of the Void Orb of Inhibition Prelude to a Hero |
Offering of the Void: 4-piece: after an Exhaust effect, Void damage rises 20% for 1 turn.
Orb of Inhibition: 4-piece: Void cards that hit 2 or more times deal 30% more damage.
Prelude to a Hero: 4-piece: discarding a Passion or Void Attack card grants +15% Crit Chance for 1 turn (caps at 15%).

Instinct
|
Instinctual Growth Judgment's Flames |
Instinctual Growth: 4-piece: once you've played 4 or more cards, Instinct damage rises 20%.
Judgment's Flames: 4-piece: Instinct damage against Ravaged enemies rises 50%.
|
Order
|
Bullet of Order Beast's Yearning |
Bullet of Order: 4-piece: after an Attack card, Order damage rises 10%, stacking up to twice.
Beast's Yearning: 4-piece: Justice and Order Attack cards deal 30% more damage, capped at 5 stacks per turn.

Justice
|
Beast's Yearning |
Beast's Yearning: 4-piece: Justice and Order Attack cards deal 30% more damage, capped at 5 stacks per turn.

This table only covers Memory Fragments. The base Weapon/Armor/Accessory system has no Attribute-specific bonuses in what we found — its effects trigger on conditions like card cost or Shield state instead. Full mechanics: Equipment
Which Sub-Stats to Prioritize
Not every sub-stat is worth the same. The full weight table already runs on the Memory Fragment Score Calculator — summarized here into 3 priority tiers so you know what to farm first. Gear Score
Flat ATK · ATK% · Critical Chance% · Critical Damage% · Extra Damage% · Damage over Time%
HP%
Flat HP · Flat DEF · DEF% · Ego Recovery
2-Piece Fallback When You Don't Have the Best 4-Piece Set
If the Attribute table above has no 4-piece set matching your combatant (or you haven't farmed enough pieces yet), these 6 two-piece sets require no specific Attribute — usable on anyone while you farm something better.
Level Unlock Milestone
A fact, not an opinion — taken straight from the Memory Fragment page:
Community sources disagree on the unlock level (25 or 40) — no official confirmation, so we won't lock in a number. What is confirmed: Legendary pieces drop at Difficulty 5 of Simulation, and Difficulty 5 unlocks at Captain Level 40. Upgrading needs Multidimensional Alignment Material, exchangeable at the Zeronium Shop.
About Class
We deliberately do not recommend gear by Class here. Our own glossary already flags that the exact combat role of each of the 6 Classes (tank, DPS, support, etc.) hasn't been independently verified — so any "Class X should use gear Y" advice would be a guess dressed up as a rule. Class is shown below for identification only; use it together with Attribute when planning a squad.

What's Missing Here (On Purpose)
We don't publish a "best build for character X" list — that's an opinion call other sites make by copying each other, and errors compound the same way. We also don't recommend gear by Class, since the exact role of each Class isn't independently confirmed yet. What you get instead is the mechanics of each piece and an Attribute-based reasoning path you can apply to any combatant yourself.

Sources: our own site data (Character roster, attributes and classes) and resources/czn-sets.php (19 Memory Fragment set bonuses, cross-checked between two independent community sources — already in use on the Memory Fragment Scorer and wiki pages). Attribute-set matches are computed directly from each set's own effect text, not hand-picked.
Builds FAQ
No — on purpose. We explain what each piece of a build does and show you a data-backed way to pick a Memory Fragment set based on your combatant's Attribute, instead of copying a "best build" opinion from another site.
Because we can't independently confirm the exact combat role of each of the 6 Classes yet. Recommending gear by Class without that confirmation would just be a guess — we'd rather show you the Attribute-based reasoning that we can back with a quote from the game's own set effects.
By checking whether a set's own effect text names an Attribute's damage type outright (e.g. "Instinct damage rises 20%"). A set's name alone was never enough — several sets are named after an Attribute but their effect doesn't actually boost that Attribute's damage, so they're correctly left out.
