TL;DR

TL;DR: Memories are support pieces, not your first place to overspend. Fill the slots you unlock, match colors when the bonus is worth it, and only rank up a Memory line when it actually supports the weapon and class shell you are using.

Quick Answer

Quick Answer

The official English site says Memories are items dropped by monsters or found during expeditions, each with unique stats and abilities that can even change how you approach a fight. Game8 and Gamerch add the practical rules new players need most: characters can equip multiple Memories, colored slots matter, and not every Memory deserves early upgrade materials. The clean rule is simple: equip broad-value Memories first, chase color matches second, and save rank-up resources for the line that actually supports your main weapon.

What Matters First

Fill slots as they open

Even a modest stat Memory is useful if the slot would otherwise stay empty. Get coverage first, then optimize later.

Respect the color bonus, but do not worship it

Game8 reports a 1.2x bonus when a Memory matches its slot color. That is strong, but a weak Memory in the right color can still be worse than a better Memory in a neutral slot.

Upgrade by build lane, not by rarity panic

Gamerch notes that gray Memories can rank up with candy, while higher-quality Memory lines ask for duplicates. That makes blind upgrading expensive very quickly.

Memory Slot Roadmap

MilestoneWhat changesWhy it matters
Base loadoutYou start with the first slot and can begin patching core stats immediatelyGood enough for basic early support
Adventure Rank 4Gamerch says an extra slot opensFirst meaningful jump in build flexibility
Adventure Rank 8Another slot opensColor planning starts mattering more
Adventure Rank 15Fourth slot opensReal Memory optimization becomes worth thinking about

Game8 and Gamerch both describe a more flexible rainbow-style slot in the setup, which is why broad-value Memories stay useful even before your color puzzle is solved.

Safe Early Upgrade Rules

  1. Weapon first, Memory second: if your main weapon is not carrying yet, Memory upgrades will not save the build.
  2. Rank up the lane you actually use: avoid splitting candy and duplicates across multiple half-built Memory lines.
  3. Keep this page at the system level: this guide is for the core decision, not for pretending we already have a complete public item database.

FAQ

Should I wait for perfect Memories before equipping anything?

No. Fill the slots with useful stats or effects first. Empty optimization slots are worse than slightly imperfect support in the early game.

How important is the color match bonus?

Important enough to care about, not important enough to force a bad Memory. Use it as a tiebreaker and a later optimization target, especially once more slots open.

Should I rank up every good-looking green Memory?

Usually no. Gamerch’s duplicate rule for higher-quality lines means upgrades can get expensive fast, so tie them to your actual core build before committing.
