Limbus Company: Mirror Dungeon Event Guide

A guide on the optimal choices to choose within the Mirror Dungeon.
This guide will assume you have formed a proper team comp for the dungeon so that you will be able to clear any and all Sin Affinity checks for events.



This guide documents Mirror Dungeon events and how best to proceed with them for an optimal outcome.
I’ll only be listing the “correct” outcomes outcomes. (good or nothing happens)

BEST Events

These events are the best you can get:

  • These events offer no drawback to the reward obtained.
  • The reward provided will most likely win you the run.
  • The event does not require a Sin check, therefore you have a 100% success rate to complete.

The BAD Events

You’re straight up are doomed if you encounter this event. There is no way to avoid getting this “gift”.
Both options will force the gift on you.
Do not “wave” – this will just give the gift but also make you have to fight a battle.

This gift is horrible and you do not want it. It will make enemies unstagger on your turn while usually inflicting 6-14 bleed which is not worth stagger removal as you can easily make up for that damage.

EVEN if you fail the sin check on purpose to try to avoid the gift, instead you will take 5 Party HP damage (except gloom), and you will be FORCED to do the check again until you obtain the gift or die. So if you have the incorrect sin affinity check in your party, you will straight up lose your run 🙂

HOWEVER, there is a single method to pass this event without getting the gift, and to do so you must sacrifice one of your sinners. They will die, but you will be spared the gift.
To do this, you must “Wave Back” and engage in the combat encounter, what you need to do is send a single sinner out to the fight and have them die.
Their death will make the event fail, and as a result you will not receive the gift and be spared.

>Reach out
>Allies without Wrath affinity take 16 HP damage
>Allies without Wrath affinity receive 5 Burn every start of combat
>Positive EGO gift (Helterfly’s Dream)
(Inflicting Burn to an enemy with burn already inflicts 3 Burn to all enemies)

>Nothing happens

This event is bad because you either get a bad gift while receiving massive drawbacks, or you just leave and this ends up being an empty tile instead of gaining levels or getting better events.

>Party takes 25 HP damage, those with Pride affinity are unaffected
>Positive EGO gift (Lowest Star)
(After dealing blunt damage, deal 5 SP damage also – if skill was Pride affinity, deal 3 more SP)

>Sinner Power-Up event
>Party takes 25 HP damage (except for Pride affinity)

>Take your leave. (Nothing happens)

This event EGO gift isn’t that great, who cares about dealing SP damage when you can just kill them instead? While the Sinner Power-Up event is great, depending whether you have a form to recover HP, taking 25 HP as a party can be fatal and leave you in 1-tap stagger range.
Though at least you do have the option to simply avoid this event and leave.

Ending notes

-Guide is being updated, if you find an event which wasn’t listened then mention it in the comments and it’ll be added.

Best gifts:
  • Carmilla – Having all human battles have -20% max HP makes the mirror dungeon really easy; enemies can even start off staggered with this gift.
  • Phelobotomy Pack – Each skill that deals damage heals you 7.5% missing HP; this allows all your sinners to heal from battles and sustain themselves without the need for healing sites.
  • Lithograph – Restore 5% Max HP to lowest HP ally when an enemy is staggered, if the skill used was Gluttony, heal 10% instead. – Also another great healing gift which restores flat max HP to the ally who needs healing the most.
  • Rusty Commemorative Coin – This allows single-coin skills to be used twice if they didn’t kill; this works on EGO cards too, which makes this basically another free attack.
  • Standard-duty Battery – All skills inflict 3 Rupture – more damage for all sinners; works really well with Gregor.
  • Eclipse of Scarlet Moths – 1/2 of skill damage is deal as fixed damage to a random enemy. This has a really powerful bug where the effect carries over to multiple battles. So for example, if you use a powerful EGO card and deal 60 damage; next combat, an enemy will receive 30 damage.
Good gifts:
  • Homeward – At the start of combat, all allies heal 12% Max HP – can be useful for restoring HP without having to land attacks.
  • Child within a Flask – Starting combat with +1 EGO resource is very helpful as it can allow you to instantly prepare certain EGO cards (example, Sinclair)
  • Blue Zippo Lighter – This grants more EGO resource each turn – very helpful in helping to spam EGO attacks.

-I have no respect for gifts which require an enemy to die to receive a mediocre effect.
-Also, events which give permanent buffs i.e Speed+ are very helpful for any build.
