Mirror Dungeon

**A GUIDE ON HOW TO SURVIVE IN THE MIRROR DUNGEON**

## Overview

The Mirror Dungeon is a secondary game mode in which the player traverses a randomly generated dungeon with only a limited group of Sinners at their disposal to reach the end and claim its rewards. There are several Mirror Dungeons available, with more released as time goes on. Each has different E.G.O Gifts, lengths, and number of floors available within them.

Entry to Mirror Dungeons is free. However, redeeming their prize requires at least 3 Enkephalin Modules. Currently, Mirror of the Beginning requires 3 Enkephalin Modules, whereas Mirror of Mirrors require 5-6 Enkephalin Modules.

Sin Resources persist in the Dungeon between Encounters, allowing you to save up resources where it is required.

The player can obtain Cost in Mirror Dungeons. These can be exchanged for Identity replacement, Sinner healing, E.G.O Gifts, and more whenever they land at Shop marks.

## List of Mirror Dungeons

Every Season, starting from Season 3, the previous Mirror Dungeon is replaced with a new Mirror Dungeon based on the current Season and its respective Canto. Any Starlight and progression with Starter Buffs are reset, requiring them to be reobtained with the new Mirror Dungeon.

## Mechanics

Mirror Dungeons functions differently compared to most other stages.

* Upon beginning a Mirror Dungeon run, the manager must choose 5 Sinners (alongside an Identity and any available E.G.O that the manager owns for each Risk Level) to start out with. This cannot be changed once the decision has been made, but they can be replaced or added at Shop encounters.
	+ The actual Uptie level for Identities and Threadspin for E.G.Os are used. Moreover, all Identity levels are fixed based on the dungeon max level (Unless the difficulty is higher than Normal)
	+ In Normal Mode, all Identities and E.G.Os are free of charge. At difficulties past Normal, managers are given a fixed amount of Cost to assemble a team. Currently, only 000 Identities require Cost at starting a run.

Then, the player will need to choose from a series of nodes from a map. It is not possible to backtrack, unlike Story Mode dungeons. These are the current known nodes:

#### Encounters

Mirror Dungeon enemy encounters are randomly chosen from the various enemy groups from the Story Mode, including bosses.

All combat encounter will have an attack type weakness below them. For Abnormality Encounters/Focused Encounters, Sin type weakness will be next to it. If the Boss encounter is an abnormality, both the **attack type and sin type** weakness will be displayed.

In **Hard Mode**, the node generation cannot be seen past the next jump. Moreover, all enemies are buffed at every floor.

*Exclusive to Hard Mode:*

```
"Thick Rumbling Hum" Shop Node will appear at the first node of every even numbered floor (i.e: Floor 2, Floor 4) and the last floor. Another will appear before the final boss node of the last floor.
"Dense Quietness" Rest Node will appear at the last node of Floors 1 and 5, and at the first node of Floor 3.
Floor 5's hostile encounter are always in waves of 2, excluding boss battle.

```

#### Removed Encounters

These encounters no longer exists as of 29th June 2023 update as they became obsolete with changes to the Mirror Dungeon.

### Cost

Each enemy encounter the player successfully defeats allows the manager to earn some Cost. Normal encounters give 40 Cost on clearance, Focused Encounters give 60, and Risky Encounters give 80. Floor Boss Encounters give a variable amount of Cost upon clearance, ranging from 100 on Floor 1 to 150 on Floor 3. Certain Abnormality Encounters also may give Cost as a result of certain choices.

Cost is also gained upon initial entry of the Mirror Dungeon; the exact amount of starting Cost depends on the team the manager assembled, with each 3-Star Identity in the team giving 25 starting Cost, and each 2-Star or 1-Star Identity giving 50. The 'Worthy Prize' Starter Buff and its secondary buffs also gives 50 starting Cost each, and the 'Triumphant Return' one-time Starter Buff gives 250 starting Cost.

Cost can be used for Sinner skill replacement, healing, purchasing or boosting E.G.O Gifts, or Team adjustment at either the Shops or Rest Stops

##### Gift Enhance Costs

 **III** | 125
 **IV** | 160

##### Gift Fusion Details

**Note: Only gifts of Tier** III **or lower may be fused.**

Fusing multiple E.G.O Gifts with identical Sin Affinities gives a higher chance to produce an E.G.O Gift of a specific Status Effect category:

Certain combinations of E.G.O Gifts would also produce specific Tier **IV** E.G.O Gifts:

### E.G.O. Gift

There are a total of 83 E.G.O. Gifts that you may encounter during an initial Mirror of the Lake run, and a further 17 E.G.O Gifts are unlockable through Starter Buffs. In all difficulties, you will start off with a Gift picked from 8 categories, 1 for each major Status Effect category and 1 that is completely random. This can be eventually upgraded to choosing 2 Gifts from a choice of 3 in each category, with the player only being able to choose from one category in every Mirror Dungeon run.

Battle Encounters has a certain chance of letting you pick another upon beating them: 5% for Normal Encounters, 70% for Abnormality/Focused Encounters, 35% for Risky Encounters, and guaranteed for Boss Encounters. Boss Encounters offers you to pick 1 Gift out of 3 while the rest only offers 1 choice of Gift. Having the Gift Tomorrow's Fortune increase the choices available by 1 in both cases. In addition, you can also reject any E.G.O Gifts offered if they do not suit your current run.

"Indistinguishable Space" Abnormality encounters may also give you their relevant E.G.O. Gift depending on the chosen decision. Gifts earned in this manner cannot be rejected. You will not encounter these events if you already own their E.G.O. Gift.

### Abnormality Encounters

In Abnormality Encounters, a random Abnormality whose E.G.O. Gifts you have not obtained from the Shop or via other means will appear. Abnormalities that appear in previous dungeons may appear in newer dungeons.

For an idea on what answers leads to what results, check their respective information page or their originated Mirror Dungeon page.

### Starlight

Starlight is an unique reward only obtainable in dungeons past Mirror of the Beginning. These are stored by dungeon individually , and are used to provide "Starter Buffs". These can only be used for said dungeons which has Starter Buffs, and only that dungeon. (Other dungeons are not affected by the specific dungeon's Starter Buffs.)

### Rewards

Depending on the difficulty of the type of Mirror Dungeons, managers who manages to clear them will be able to claim Lunacy and Limbus pass XP for Battle Pass with specific Enkephalin Modules.

Theres a weekly bonus limit of 3 clears before the rewards are reduced. For **Hard Mode**, you can only do one weekly bonus limit.

All Weekly Bonus limit will include 250 Free Lunacy.

## Tips:

* It is highly recommended to achieve Uptie 3+ for any Identities you plan on using. Not only can you utilize their Sin-Resonated passives, be it combat or standby, a fully uptied Identity has access to higher stats and skills only available for 00 and 000 Identity.
	+ A team consisting of the default identities of Faust, Ryoshu, and Rodion is a powerful basic team that can carry you through the first Mirror Dungeon quite easily. Ryoshu and Rodion provide Bleed, while Faust's passive increases the damage she deals for every status ailment on an enemy.
* It is recommended to do the dungeon mission during the start of a new day due to the cost of Enkephalin required to forge Enkephalin Modules required for redeeming the rewards after a run. Any Enkephalin used will slowly regenerate, even while a Mirror Dungeon or Story Dungeon is in progress.
	+ A common strategy as of now is to do daily missions that include missions (as the dungeon does not count as one), then turn all remaining entry into Modules, and run though the dungeon twice, and another using the modules gained from turning remaining energy into Modules.
	+ One Enkephalin box gives just enough for one Mirror Dungeon reward claim of the lowest difficulty.
* Be mindful of the ZAYIN E.G.O. and identity picked for each sinner, especially if there is a section of Sin or damage type that are fatal to them, as those that were not initially picked will not be usable until you buy them from Shop during the run.
* Before tackling Hard Mode Mirror Dungeons, it is advised to cap out the level of sinners and the identities you intend to (or later on) bring over to the dungeon, alongside with capping out the Starter Buffs and all E.G.O and Identities Uptie/Threadspin to their max whereby possible due to the spiked difficulty of the battles.
