How Passives Work in Project Mirror Labyrinth
In the Roblox roguelite deck builder Project Mirror Labyrinth, your combat performance relies heavily on project mirror labyrinth passives. While your active deck manages your immediate attacks and blocks, your equipped passive abilities run in the background to multiply your damage, recover your Posture, and apply devastating status effects like Burn, Bleed, or Bind.

The Passive System Explained
Passives are divided into distinct categories based on how they are obtained and where they can be used. To build an effective character, you must understand how to manage your Attribution Points (ATP) and unlock slots.
| Passive Type | How to Unlock | Primary Purpose |
|---|---|---|
| Attributable Passives | Unlocked via Outfits and Defragmentation | Standard equippable passives that cost ATP to slot. |
| Killing Unlockables | Defeat specific enemy types in dungeons | Grants targeted slayer bonuses against faction enemies. |
| Quest Unlockables | Complete NPC tasks (e.g., Courier runs) | Grants specialized utility and speed passives. |
| Labyrinth Only | Found during active dungeon runs | Temporary run-specific buffs that do not persist in the lobby. |
Every standard passive requires a set amount of ATP to equip. Even if you unlock an S-tier passive, you cannot slot it unless your outfit has enough available ATP capacity. Prioritize upgrading your primary outfits to expand your ATP pool.
How to Unlock and Upgrade Passives
Unlocking the true potential of your project mirror labyrinth passives requires progressing through the game's outfit development system. You cannot simply buy passives; you must earn them by pulling Outfits from Reflections and defragmenting them.
Acquire Outfits from Reflections
Use your Fragments to pull Outfits from either Targeted or Standard Reflections. Outfits serve as the physical containers for your permanent passives.
Gather Upgrade Materials
Collect essential currencies including Condense and Seeds of Light. These are rarely awarded via active promotional codes or earned through high-tier dungeon clears.
Defragment Your Outfits
Navigate to the Outfit menu and select Defragment. Spend your Condense and Seeds of Light to upgrade the outfit, which directly unlocks its locked passive abilities.
Attribute Passives in the Lobby
Open your Passives menu in the lobby before entering a dungeon. Allocate your available ATP to equip the unlocked passives onto your active build.
Condense and Seeds of Light are highly limited resources. Do not spread your materials thin by defragmenting low-tier starter outfits. Save your upgrade materials for SR or meta-relevant outfits that offer high-value passives.
Meta Passives and Attribution Cost
To help you optimize your deck builds, we have compiled a list of the most influential permanent passives discovered in Project Mirror Labyrinth. These passives are sorted by their unlocking methods, combat utility, and ATP requirements.
Attributable & Quest Passives
| Passive Name | ATP Cost | Combat Effect | Unlock Condition |
|---|---|---|---|
| Sturdy I | 1 ATP | Max Health +7 (Does not stack) | Unlocked by default / Free. |
| Association Slayer I | 1 ATP | Deal 15% more damage against Association Fixers | Defeat Association Fixer tagged enemies 20 times. |
| Association Slayer II | 2 ATP | Gain +1 Final Power against Association Fixers | Defeat Association Fixer tagged enemies 50 times. |
| Speedy Courier | 1 ATP | Increases combat speed and action options | Complete the Speedy Delivery Quest under time limits. |
| Outstanding Courier | 2 ATP | High-tier utility and action optimization | Complete the Devyat Courier Quest in under 20 minutes. |
E.G.O. Linked Passives
E.G.O. weapons come with built-in passives that trigger automatically when the weapon's posture requirements are met during dungeon runs.
| E.G.O. Passive | Posture Cost | Affinity | Passive Combat Effect |
|---|---|---|---|
| Dimension Shredder | 15 Posture | Pride | On hit, inflict Dimensional Rift on target equal to Charge Count / 8. |
| Crow's Eye View | 12 Posture | Sloth | When damaged by an Action, gain 2 Bind and 1 Damage Up next turn. |
| Representation Emitter | 12 Posture | Pride | On Stagger, 1 ally with the lowest Posture recovers 4 Posture. |
| Screwloose Wallop | 10 Posture | Envy | Gain 1 Surgery (Surgery doubles Offensive Power Up and halves Fragility). |
| Fourth Match Flame | 20 Posture | Wrath | On a successful attack, inflict 1–2 Burn to Target and self. |
Combining E.G.O. passives with your standard attributable passives is the key to mastering high-difficulty dungeons. For example, running a Burn-focused outfit with the Fourth Match Flame passive allows you to stack massive damage over time while mitigating self-burn through defensive cards.

Frequently Asked Questions
Q: How do I get more Attribution Points (ATP) to equip more project mirror labyrinth passives?
Your available ATP is tied directly to your equipped Outfit. To increase your ATP capacity, you must pull higher-tier outfits (such as SR outfits) and use the Defragment system to upgrade them using Condense and Seeds of Light.
Q: Do Killing Unlockable passives cost ATP to equip?
No. Killing Unlockables, such as the Association Slayer series, are permanent situational buffs that automatically apply when fighting specific tagged enemies, though some advanced variations may require standard slotting depending on your current build version.
Q: Can I use multiple E.G.O. passives at the same time?
Yes. E.G.O. passives are active during dungeon runs and trigger automatically when you play the corresponding E.G.O. card and meet its Posture and Affinity requirements.
Q: What is the fastest way to get Condense and Seeds of Light for passive upgrades?
The fastest way for new players to get these materials is by redeeming active codes like 'Welcome', which grants 500 Condense and 3 Seeds of Light instantly. Beyond codes, you must farm high-level Luxcavations and dungeon runs.
