Limbus Company EGO Gift and Resonance Guide

Mirror Dungeon runs live and die on two systems: EGO Gifts and Sin Resonance. Gifts are the little trinkets you pick up as you crawl through a run, and each one nudges your team somewhere - more Burn, more Charge, more clash power, free heals. Resonance is what happens when several Sinners throw skills of the same Sin in the same turn. Get both working together and a pretty average lineup starts hitting like a truck.

The two systems feed each other, too. A surprising number of gifts only fire when you hit Absolute Resonance, so your gift picks and your skill order end up deciding each other.

How EGO Gifts Affect Sinner Builds

EGO Gifts are run-long buffs. You collect them inside the Mirror Dungeon from fights, Abnormality events, shops, and fusion, and they stay active for the rest of that run. Nothing carries over when the run ends. Story dungeons (the Canto chapters) have their own separate gift pools, mostly locked to each chapter, but the deep end of gift play is the Mirror Dungeon. The current one, Mirror of Immortality, has a pool of 319 gifts.

Every run opens with a free pick: one tier 2 gift out of ten categories. Seven categories are the Sins (Wrath, Lust, Sloth, Gluttony, Gloom, Pride, Envy) and three are damage types (Slash, Pierce, Blunt). Pick for the team you brought, not the gift that sounds coolest.

Gifts read your roster, not the other way around

Gifts rarely just say "get stronger." They check things: sin affinity, status keyword, damage type, faction, coin count, deployment slot. Phlebotomy Pack (tier 1, 142 Cost) heals 12.5% of a unit's missing HP whenever that unit lands a hit - and a full 25% if the skill used was Wrath. Short Cane Sword gives Seven Association Identities extra perks nobody else gets. Awe only applies to your #1 and #2 deployed Sinners. Rusty Commemorative Coin wants single-coin skills. Torn Bandolier wants Pierce and Ammo.

So a build isn't just "which Identities are strong." It's which gifts their skill sets actually switch on. A Seven Association team turns a 207 Cost trinket into a faction-wide weapon.

Keyword gates and team-wide payoffs

The top-end fusion gifts have entry requirements. The Burn ladder (Secret Cookbook and everything above it) sits dormant unless at least five of your deployed Identities have attack skills that apply Burn. The Bleed ladder works the same way. Bring three Burn IDs and a mixed bag, and those tier 3 and 4 gifts do absolutely nothing for you.

Keyword density is the whole game here. If you want the big status payoffs, commit - most of the team should be applying the same status, and your gift picks should follow that keyword. Half-committing is the number one way a run feels weak by floor 3.

Resource gifts count too. Coffee and Cranes (tier 2, 186 Cost) refills EGO resources for sins you didn't even use last turn, which gets EGO skills online early - and EGO skills often carry their own sin, feeding right back into resonance.

Shop actions that quietly break a build

Mirror Dungeon shops let you replace a Sinner's skills, one at a time. The wiki itself warns about the risk: replacing a skill can strip out the exact sin or keyword a gift was keyed to. If an Identity only had Gloom on the skill you just swapped away, every "Gloom allies get X" gift you own just lost a trigger. Swap carefully once your gift engine is running.

Duplicates deserve a mention too. Any copy of a gift past the first auto-converts into a fusion-only version. It won't double the effect, but it's perfect fuel for the fusion pot later in the run.

Resonance Mechanics and Stacking Rules

How the chain gets built

Each turn, every Sinner throws one picked skill. The dashboard lines everyone up by Speed, fastest on the left, with ties broken by priority number. The picked skills, read left to right, form the chain - and that chain is what resonance cares about. Speeds change turn to turn (Haste, Bind), so the order can shuffle under you mid-fight.

Normal Resonance: two is the minimum

Pick two or more skills of the same Sin anywhere on the dashboard and that Sin resonates. The skills don't need to be adjacent. The bonus scales with each skill's spot among the same-Sin picks - the first one gets nothing, the second gets a little, and the deeper you go the fatter it gets.

Absolute Resonance: three in a row

Line up three or more of the same Sin consecutively - directly next to each other in the chain - and you get Absolute Resonance (A-Reson. in the game's shorthand). Two things change. Every skill in the run gets the same bonus instead of a ramping one, and the bonus is bigger. A chain of four gives all four skills +5, while four non-adjacent same-Sin skills would only hand out +1 and +3 to the later picks.

Two quirks worth knowing. Separate chains count separately: two different runs of three count as three each, not six, for anything that checks "3+ A-Resonance." And Absolute Resonance always counts as normal Resonance too, so gifts that trigger on plain Resonance still fire.

| Same-Sin skills | 1st | 2nd | 3rd | 4th | 5th | 6th | 7th | 8th | 9th | 10th | 11th+ | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | Resonance bonus | none | +1 | +3 | +3 | +5 | +5 | +7 | +7 | +9 | +9 | +11 | | Absolute bonus (chain length) | none | none | +3 | +5 | +5 | +7 | +7 | +9 | +9 | +11 | +11 |

Those numbers are Offense and Defense Level, and they cap at +11. The Absolute row reads by chain length: a chain of 5 gives every skill in it +5.

What those levels actually buy

Offense Level pumps clash power and damage. Defense Level does the soaking on the other side. The wiki's framing is on point: an underleveled Identity with big resonance bonuses can clash like a properly leveled one. In the current Mirror Dungeon everyone is pegged at level 55 anyway, so resonance is one of the few levers left for pulling ahead of the content.

One more nice edge: enemies basically can't use resonance. Only your Sinners and one late-game enemy family (the Peccatula Invidiae) get it. It's your trick.

Gifts and skills that check the chain

Plenty of gifts trigger directly off resonance, and they're the bridge between the two halves of this guide. Employee Card fires on Wrath Absolute Resonance, handing +3 Charge Count to every ally next turn. Dreaming Electric Sheep gives all allies +2 Offense Level and +2 Defense Level when you pull off Envy A-Resonance. Barbed Lasso drops Rupture on the enemy side for Lust A-Resonance, and Hellterfly's Dream sprinkles 5 Burn Potency around on Wrath A-Resonance. Some skills and passives check the chain too, and the tier 4 gift For the Capo wants 4+ Wrath Resonance before its biggest effect kicks in.

The stacking rules of thumb, then: build the team around one or two Sins, keep an eye on speed order so your same-Sin picks actually sit next to each other, and grab the gifts that reward the Sin you're already stacking. Half the roster on Gluttony and half on everything else just builds weak chains.

Best EGO Gift Combos for Support Sinners

"Support" in Limbus is less a fixed role and more a set of gifts that prop up the whole team or feed one carry. These are the pairings that do the most work per Cost.

The Envy engine

Dreaming Electric Sheep is a tier 2 starter (198 Cost) that hides a team-wide buff: when you pull off Envy Absolute Resonance, every ally gains +2 Offense Level and +2 Defense Level. An Envy-heavy lineup can fire that in nearly every fight, which is basically a permanent stat lead. Later in the run, Rules of the Middle (tier 4, from the Ricardo EXTREME boss) doubles down - with three or more Middle faction IDs fielded, every Envy Resonance grants an Attack Power Up and Protection, up to three stacks.

So who wants this? Any roster that can line up three Envy picks in a row without wrecking its skill choices. That bar is lower than it sounds with twelve Sinners available.

The Charge battery

Employee Card (tier 2 starter, 195 Cost) is silly value: activating Wrath Absolute Resonance, or just using any skill that gains or applies Charge, gives +3 Charge Count to every ally at the next Turn Start. Once per turn, every turn. Portable Battery Socket (190 Cost) drips +2 Charge to two random allies each turn, and Sloth A-Resonance squeezes out +3 more for one of them.

Charge Count caps at 20 and hungry IDs burn through it fast; this pair keeps the battery topped up without anyone wasting a skill slot.

Buff drippers and skill power

Fluorescent Lamp (tier 2 starter, 219 Cost) hands out 1 Damage Up or 1 Haste to a random ally every Turn End, and repeats the handout once per enemy carrying Rupture, plus one extra time. Five ruptured enemies means six procs a turn. Bloody Gadget (tier 1, 163 Cost) is cheap as dirt and gives 2 Damage Up per turn - 3 if it lands on a Lust user - and each Damage Up is +10% damage.

Cigarette Holder converts Poise into 1 Power Up per turn for anyone holding it, or 2 at 5+ Poise Count. Burning Intellect feeds Damage Up to two Burn allies on every Burn-flavored kill. Red Order does the same trick for Sinking teams, giving Gloom and Wrath inflictors +2 Offense Level per application, max 4 per turn.

And then there's Sunshower (tier 3, 252 Cost), probably the strongest straight support pick in the pool: activate Sloth Absolute Resonance or use any skill with 2+ Atk Weight (meaning it swings at multiple targets), and all allies gain +2 Skill Power. Skill Power boosts are rare and expensive. This one asks almost nothing.

Sustain and resources

Phlebotomy Pack keeps a frontline alive all run for 142 Cost - missing-HP healing means the beat-up units benefit most. The Family's Resentment (tier 4, La Manchaland-flavored) turns Bleed skills into life steal, healing 30% of damage dealt. Coffee and Cranes refills EGO resources for sins you didn't touch last turn, so your EGO skills come out early and often. On the debuff side, Melted Spring strips 3 Offense and Defense Level from every enemy carrying Sinking, every turn, which is support by another name.

Park your carry in deployment slot 1 or 2 when you're leaning on these. Several of the best gifts (Awe, Sour Liquor Aroma, Grandeur) only look at the first two slots, and buffs that pick "a random ally" get a lot less random when half your team is hurting.

Best EGO Gift Combos for Damage Dealers

The Burn engine

Fiery Down (tier 2 starter, 203 Cost) is the spark: every hit with a Lust skill or any Burn-applying skill adds 3 Burn Potency, and at Turn Start any enemy sitting on 20+ Burn gets its stack doubled. Doubling is the good stuff - that's exponential, not linear. Decamillennial Stewpot (tier 2, 208 Cost) adds +1 Clash Power to every Burn skill so you win the coin fights that apply the Burn in the first place. Dust to Dust (tier 3, 231 Cost) opens each wave with 5 Burn Potency and +3 Count on everything, plus another 3 and +2 whenever Sloth A-Resonance goes off.

Fuse the ladder up and it ends at Soothe the Dead (tier 4, 421 Cost): +6 Burn Count to all enemies and 15 random Burn Potency per wave, plus Final Power, Coin Power, and extra Burn on every plus-coin Burn skill. Remember the gate - five or more IDs with Burn attack skills, or it's a paperweight.

The Bleed engine

Wound Clerid (tier 2 starter) adds 4 Bleed Potency whenever a hit already inflicts Bleed. Little and To-be-Naughty Plushie (207 Cost) gives +10% damage into Bleeding enemies and -20% damage taken from them, and Pride IDs get the doubled version: +20% and -30%. Awe (also a tier 2 starter, slots 1-2 only) adds +10% damage against targets holding 7+ Bleed Count. Millarca (204 Cost) is the Bleed mirror of Stewpot, +1 Clash Power on Bleed skills.

The fusion ladder here ends at Bloody Mist (tier 4, 418 Cost): double Bleed Potency and Count from skill effects, and your top-deployed ally gets Coin Power +2 and +100% damage on plus-coin Bleed skills. Everyone else still gets +30%. That's a nuke with a team attached.

Slot one carries

Some of the spiciest gifts only work on the #1 and #2 deployed Sinners, so park your main attacker there and hand them the keys. Sour Liquor Aroma (185 Cost) gives Tremor-applying skills +2 Offense Level and bonus damage that scales with the target's Stagger Level. Grandeur (215 Cost) does the Sinking version, dumping extra Potency and Count on targets holding 10+ Sinking.

Rusty Commemorative Coin (tier 3, 270 Cost) is a personal favorite for single-coin nukers: the first single-coin attack skill each fight repeats if it doesn't kill - a free second swing at a boss - and kills grant +1 Skill Power next turn. Eclipse of Scarlet Moths (220 Cost) echoes the first attack each turn as half its damage in fixed damage onto another enemy, or two enemies if the skill was Lust.

Pierce, Ammo, and Wrath

Torn Bandolier (tier 2 starter, 190 Cost) is the Ammo pick: +1 Clash Power on Pierce skills, bonus damage on Ammo skills that scales on coin count, and 2 Ammo back the turn after you run dry. For the Capo (tier 4, from the Lei Heng EXTREME boss) is the Wrath Resonance payoff - at 4+ Wrath Resonance, Wrath skills gain Coin Power +2 and +30% damage on hits that spent Ammo. Blunt teams should grab Temporal Bridle (212 Cost), which hands +1 Offense Level per turn to anyone holding a Blunt skill, and more for units with two or three.

The common thread: clash power first, then damage. Offense Level from resonance plus the +1 Clash Power gifts is what keeps your attacker actually landing hits.

Farming and Crafting Rare EGO Gifts

Where gifts actually drop

The full spread of sources in a Mirror Dungeon run:

• Starter pick - one free tier 2 gift from ten keyword categories, right at the start.
• Post-battle drops - about 5% after Normal encounters, 35% after Risky ones, 70% after Abnormality and Focused encounters, and guaranteed after Bosses. Bosses let you pick 1 of 3 gifts on Normal, or 2 of 4 on Hard.
• Abnormality events - picking the right option in an Abnormality event can hand you its themed gift. These can't be refused, so sometimes you eat a dud.
• Shops - every floor has one before the boss node. Gifts run 140 to 600 Cost, a Refresh is 15 Cost plus 15 more each time, and the 90 Cost Keyword Refresh biases the pool toward a keyword you choose.

Duplicates past the first copy auto-convert to fusion-only versions.

Gift Search: the deterministic pull

After the starter pick, Gift Search lets you buy chosen gifts straight up with Starlight: 70 for one, 160 for two, 270 for three. Anything tier 3 or lower is fair game, including gifts locked behind specific theme packs - but not recipe-only fusion results. This is how you force Sunshower or Rusty Commemorative Coin into a run instead of praying to the drop rates. Starlight comes in around 60 per run plus bonuses for Hard floors and Rest Bonus charges, so it piles up across a week.

Fusion math

Fusion at a shop is free. You pick a keyword category, toss gifts in the pot, and see what comes out.

| Gifts fused | 2 | 3 | 4 or more | | --- | --- | --- | --- | | Base chance of the chosen keyword | 60% | 90% | 99% | | With Wishmaking (5 Starlight) | 90% | 99% | 99.99% |

The result's tier comes from a points system: tier 1 gifts are worth 3 points, tier 2 is 6, tier 3 is 10, tier 4 is 15, and the rarest slot is 30. Up to 10 total points spits out a tier 1, 11 to 16 gets tier 2, 17 to 24 gets tier 3, and 25 or more gets tier 4. Rule of thumb: the result is about the average tier of what you threw in, rounded down.

Certain fixed recipes produce exclusive gifts you can't buy or pull any other way. That's the crafting system, really - the Burn ladder climbs through Secret Cookbook to Soothe the Dead (421 Cost), the Bleed ladder climbs to Bloody Mist (418), and Purloined Flame (404) sits at the top of its own chain. Super Shops, which only spawn on Hard floors, fuse up to 5 gifts at once with slightly friendlier tier thresholds.

Enhance, sell, or feed the pot

Enhancing is the other half of crafting. Not every gift can be enhanced, but the ones that can take two levels: 50 then 100 Cost for a tier 1, 60 then 120 for tier 2, 75 then 150 for tier 3, and 100 then 200 for tier 4. Enhancing a gift you're keeping all run is almost always worth it - a strengthened engine gift pays for itself by floor 3.

Hard mode and the EXTREME bosses

Hard floors pay more Cost per fight (85 versus 75 on normal encounters, 250+ versus 200+ on floor bosses), and only Hard floors can roll Super Shops - the odds start at 3% and climb 1% for every 20 Cost you've spent at shops, so big spenders get rewarded. Clearing all five floors on Hard unlocks Parallel Superposition, which stretches the run to 10 floors, and since September 2025 clearing floor 10 of that opens EXTREME, which goes to 15.

EXTREME is where the rarest trinkets live. Around 10% of non-boss, non-shop nodes turn into hidden boss fights, and beating one pays out an exclusive tier 4 gift, 1000 Cost, and a full team heal. In the current pool those bosses are Don Quixote, Ricardo, Lei Heng, and Kkomi and Vergilius. Fair warning: you can't forfeit once you step into one of those nodes, so go in with a real build.

One EXTREME boss kill hands you a tier 4 gift plus 1000 Cost - more spending money than most full runs ever see. And those duplicate gifts you kept? That's exactly what the fusion pot wants.
