Every memory shines with a color. Learn how to match them and dominate every stage.
The Core Insight: Stellactrum matching is the single biggest damage multiplier most players ignore. A fully matched stellactrum set gives up to +60% stat bonus 閳?more than any single protocore or memory level. If you're struggling on Abyss floors, the problem isn't your gear. It's your colors.
Every Memory in Love and Deepspace has a Stellactrum color. These colors correspond to elemental affinities and resonance patterns. When you enter a combat stage, the game checks your equipped memories against the stage's color requirements.
If your colors match the requirement, your operative receives a massive stat multiplier. If they don't match, you're fighting with a severe handicap 閳?even if your memories are fully leveled.
There are six Stellactrum colors in the game. Each has a corresponding element and stat affinity:
Every stage displays its Stellactrum requirements in the top-right corner of the preparation screen. The requirement shows a pattern of 6 slots, each requiring a specific color.
Your job is to equip memories whose colors fill each required slot. The match is binary: either the color matches or it doesn't. There's no partial credit for similar colors.
Each character has a natural affinity for certain Stellactrum colors. This affects which memories are optimal for them:
This doesn't mean you should only use these colors 閳?but when building a general-purpose loadout, prioritizing a character's affinity colors gives you the most flexibility across different stages.
Let's put the Stellactrum bonus into perspective. Consider two otherwise identical setups:
That +60% is multiplicative with your protocore bonuses, memory levels, and resonance skills. It's not a separate damage bucket 閳?it's a global multiplier on your operative's base stats. In practice, this means a 6/6 match with level 50 memories can outperform a 0/6 match with level 70 memories.
Reality Check: Many players spend weeks farming protocores for a 5% damage increase, while ignoring the 60% bonus sitting right in front of them. Fix your stellactrum matching first. Then optimize protocores.
The endgame challenge is building enough depth in each color to handle any stage requirement. Here's a step-by-step strategy:
In multi-team stages (Abyss Floor 9+), you need to manage stellactrum across two or three teams simultaneously. This demands a different approach:
Pool Your Resources: Don't build memories for each character in isolation. Look at the combined color requirements across all teams. A memory that's mediocre on your main team might be the perfect color fix for your third team. Cross-team flexibility is more valuable than per-team optimization.
Swap, Don't Level: Before leveling a new memory for a specific color slot, check if you can simply swap an existing leveled memory from another character. Memory sharing between operatives is free 閳?use it aggressively.
Once you have solid color coverage, the next optimization layer is protocore synergy. Each color slot on a memory can hold a protocore of the same color for a set bonus:
The 6-piece bonus is particularly powerful. For example, a full Ruby set on Xavier grants not just +45% ATK but also a chance to trigger an additional light blade hit on crit. These set effects are often what separate a "good" build from an "S-tier" build.
Mistake #1: Leveling memories without checking their color You pulled a new 5-star memory and leveled it to 70 immediately. But its color is Garnet 閳?and you already have five Garnet memories maxed. You just wasted a week's worth of resources. Always check your color inventory first.
Mistake #2: Ignoring 4-star memories 5-star memories are better, but a 4-star memory of the right color at level 60 is far more useful than a 5-star memory of the wrong color at level 70. Don't bench your 4-stars 閳?they're your color gap fillers.
Mistake #3: Tunnel-visioning on one character Building a single perfect set for Xavier while Zayne and Rafayel have 0/6 matching is a common trap. Abyss requires three teams. Spread your resources to cover all four operatives with at least a 4/6 match each.
Mistake #4: Forgetting to re-check stage requirements The stellactrum requirement changes every Abyss rotation. Your Floor 12 setup from last month probably won't work this month. Always review the color requirements before locking in your team.
The Bottom Line: Stellactrum is the most misunderstood system in Love and Deepspace. New players ignore it. Intermediate players half-match it. Elite players build their entire roster around it. The difference between a 4/6 and a 6/6 match is a free +30% stats 閳?that's like equipping an entire extra memory on every operative. Check your colors before every stage. Build your inventory with color depth in mind. And never, ever waste resources on a memory whose color you don't need.
