Limbus Company Mirror Dungeon 4: Best Builds and Fusion
Complete Limbus Company Mirror Dungeon guide: 5-floor progression, E.G.O Gift fusion odds, shop restock costs, and optimal keyword team archetypes.
Deploy your 6-Sinner combat squad, track Sin affinity resonance live, calculate E.G.O resource generation, and benchmark status archetypes across Tremor, Sinking, Rupture, and Bleed.
Deploy 6 frontline Sinners to instantly map Sin affinity pools (18 deployed slots) and calculate E.G.O skill resource generation in real time.
Benchmark your squad against the 7 core battle archetypes: Tremor (Reverb), Sinking (Deluge), Rupture (Count), Bleed, Burn, Charge, and Poise.
Direct access to Level 65 baseline metrics: maximum HP, Defense scaling, Speed ranges, coin counts, and fatal stagger thresholds.
Limbus Company is the free-to-play turn-based RPG from Project Moon, the studio behind Lobotomy Corporation and Library of Ruina. You run a bus of twelve Sinners into buried facilities in search of Golden Boughs, and every fight resolves through skill coins: units that attack each other Clash, the weaker side loses coins one at a time, and the survivor spends what it still holds on the enemy.
Identities are the loadouts you hang on those twelve characters, each with three skill lines of its own, and E.G.O supplies the extra skills that a matched lineup can activate. That makes squad work a bookkeeping problem before it is a preference problem, which is what the builder below is for.
Deploy 6 frontline and 6 reserve Identities. The tactical terminal computes 7-Sin generation, E.G.O fueling deficits, status archetype synergy, and physical damage balance in real time.
Each card counts the harvested skill lines that apply the status, so the coverage figures describe this 19-Identity sample and nothing else. The status amount column is the value the source page records for those lines, given as a range because different skills apply different amounts.

| Status | Trigger | Effect |
|---|---|---|
| Bleed | The unit tosses an attack coin | Takes fixed damage equal to Potency, then Count drops by 1, so multi-coin skills trigger it several times in one turn. |
| Rupture | The unit is hit by an attack | Takes fixed damage equal to Potency, then Count drops by 1. |
| Sinking | The unit is hit by an attack | Takes fixed Sanity damage equal to Potency; units without a Sanity meter take Gloom damage instead. |
| Burn | End of the turn | Takes fixed damage equal to Potency, then Count drops by 1. |
| Tremor | An attack that bursts Tremor lands | Raises the target's Stagger Threshold by the Tremor Potency, and Count drops by 1 at the end of the turn. |
| Charge | Held by the unit, spent by skills | A resource some skills consume for extra effects. It stacks up to 20 and loses 1 at the end of each turn, so spending it is a timing decision. |
| Poise | The unit's attack lands | Grants a Potency-based chance to turn the hit into a critical, and a critical consumes 1 Count. Critical hits deal 1.2x damage. |
A Clash starts when two units attack one another with skills. Both sides toss every coin of the colliding skills, and the side whose skill has the lower clash power loses one coin. If it still holds coins the duel runs again, and it keeps running until one side is out. That side then takes the remaining coins of the winner as a one-sided attack phase. Because Offense and Defense levels usually add clash power during a duel, a skill that wins the first exchange often wins the rest of them too.
Sanity Points sit in a range of -45 to 45, and the odds that a coin lands on Heads equal 50 plus current SP: the worked examples on the source page are 27 SP for a 50+(27)=77% chance and -33 SP for a 50+(-33)=17% chance. Cross -30 and a Sinner risks Low Morale; reach -45 and they Panic and lose the turn, or fall into E.G.O Corrosion when they are carrying a non-personal E.G.O, with SP held at -45 until the next Turn Start and reset to 0 after that turn. Sinking drives enemies down this dial by fixed Sanity damage, which is why it is the archetype that fights the meter itself.

A tier list claims to rank overall value, and overall value in Limbus Company depends on Uptie levels, E.G.O enhancement, passives that scale with other units in the same squad, and the specific encounter you bring the team to. The Identity pages we harvest publish none of those for every unit in this sample, so a composite score built on top of them would be arithmetic pretending to be judgment. What this board does publish is measurable: who is toughest, who swings hardest per coin cycle, and whose skill lines cover the most status effects.
If you want the archetype view instead, the sample splits into 17 three-star and 2 two-star Identities, added between 2023.02.27 and 2025.05.22, and Sinking is the most represented status across the 57 harvested skill lines.
12 of the 19 catalogued Identities publish all three stagger gates and the rest print only the gates the Wiki lists for them; each page gives its gates as a share of current HP, which is what Tremor play pushes against once a target's threshold rises. The same pages list how the unit takes Slash, Pierce and Blunt damage, from Fatal at double damage down to Ineff. Reading the two together tells you whether a body slot wants thickness or damage output, and the panel table above counts the Fatal weaknesses so a fragile pick is a deliberate one.

How Limbus Company teams work from harvested Identity data: clash rules, six deployed slots, Sin and damage-type coverage, and panel math you can recheck.
Select 6 frontline combat Sinners and 6 reserves to evaluate your squad. The tactical terminal calculates your deployed Sin affinities in real time, displays Sin Resonance distribution to verify E.G.O fueling, and tracks active status archetypes.
Sin Resonance activates when 2 or more skills of the same Sin affinity are chained on the combat dashboard, increasing final skill power and offense levels. Absolute Resonance (3+ consecutive identical Sins) grants massive combat multipliers and fulfills E.G.O passive conditions.
Sinking (utilizing Sinking Deluge via Spicebush Yi Sang to burst tens of thousands of damage), Tremor (utilizing Tremor - Reverb to convert stagger Potency into direct Sloth damage), and Rupture (stacking Count to trigger +99 fixed true damage per hit) dominate high-difficulty content.
Sanity Points range from -45 to +45. The probability of landing Heads on coin flips is exactly (50 + current SP)%. At maximum +45 SP, Sinners have a 95% chance to land Heads, ensuring consistent maximum clash power and skill damage.
Stats for the 19 core meta Identities reflect verified Level 65 baselines, including maximum HP, Defense level adjustments, Speed brackets, coin counts, and stagger thresholds calculated directly from official combat formulas.
19 Identity pages plus the E.G.O and template pages they depend on, parsed from the Wiki's own source text by scripts/harvest_identities.py and written into src/data/builder-data.json. Level 65 HP and Defense come from the formulas on those pages, so no figure on this site was typed in by hand.
6 E.G.O records and 4 preset squads ship with the same dataset. The rules summarised above come from the Wiki's Battles, Status Effects, Sanity, Mirror Dungeon and E.G.O Gifts articles, captured by scripts/harvest_reference_pages.py.
Every captured page is stored in this repository as a file with a SHA-256 entry in researchPack/sources_raw/manifest.json (43 verified snapshots). If a future Wiki edit changes a number, the checksum stops matching and the site's fact gate fails the build instead of shipping the stale figure.
