New Content - Mirror of Names and Spiders EXTREME Mode · Mirror Projection / Achievements

March 11, 2026

Greetings, Dear Manager.

New Content <Mirror of Names and Spiders EXTREME Mode · Achievements> will be added to the game with the Mar. 12th, 2026 (KST) Scheduled Update.

※ For the Mirror of Names and Spiders EXTREME Mode and Achievements implementation, Mirror Dungeon entry will be blocked for the following period: 2026. 03. 12 06:00 ~ 10:00 (KST). Please note this information for your gameplay plans.

<Description>

- Once you reach Floor 10 via the Parallel Superposition Mode in Mirror of Names and Spiders, the “EXTREME” mode, which unlocks Floors up to 15, will be unlocked.

- Mounting Trials and Adversities will greatly empower the enemies compared to Parallel Superposition; the higher your Floor, the more Starlight and Projection you will obtain.

- You can increase your Projection rate by attaining Mirror Dungeon Achievements. Every time your Mirror Dungeon Projection levels up, you will be able to obtain Projection Level rewards.

- Several Quality-of-Life improvements have been applied to the Mirror Dungeon content.

- For more information, please refer to the [QoL Improvements] section on the last page of this notice.

※ With the Mar. 12th EXTREME Mode update, 14 Theme Packs, which were selectable in the Mirror of Immortality EXTREME Mode, will be made available. Additional updates to the new EXTREME Mode will include its own new selectable Theme Packs.

※ The Mar. 12th EXTREME Mode update also brings 4 Hidden Bosses encountered in the Mirror of Immortality EXTREME Mode. Additional updates on new Hidden Bosses will convert existing Hidden Bosses into EXTREME-exclusive Theme Pack Encounters.

※ The 4 E.G.O Gifts obtainable from existing Hidden Bosses will remain obtainable by winning those Encounters. However, please note that they will not be added to the E.G.O Gift Compendium, and will not count towards the tally of certain “collection” Achievements.

Adversities

- For Parallel Superposition EXTREME, in addition to Mounting Trials applicable when entering Floor 11, you will have an option to set “Adversities” for yourself.

- Starting from Floor 11, up to 5 Adversities can be selected on each Floor. Just like Mounting Trials, Adversities will continue to compound instead of going away.

- Selecting more Adversities will net more Adversity rewards; you will gain additional Starlight & Projection based on your cumulative Adversity Score.

- Please note that Mirror of Immortality Achievement EXP can be gained only until the update of the next Mirror Dungeon.

※ Adversities aren’t mandatory; you can reach Floor 15 without setting any Adversities, which may still be a good way to experience the dungeon.

Selecting Theme Packs

- You can select among 14 Theme Packs unique to Parallel Superposition EXTREME for your progression.

- Mounting Trials & Floor Clear Rewards are the same as they are in HARD mode: 2 Reward E.G.O Gifts and 2 Mounting Trials attached to each Gift.

※ Please note that Theme Pack Search will be disabled past Floor 11.

Hidden Bosses

- From Floor 11 onward, there is a set probability that a Hidden Boss will appear before entering any node, excluding Shop and Boss nodes.

- You may choose to either engage the intruding Hidden Boss or withdraw from the encounter.

- If you withdraw from the Encounter, the Hidden Boss Battle will not take place, and you may proceed to the next node.

- Upon defeating the Hidden Boss, you may obtain the corresponding E.G.O Gift.

※ Even if a Hidden Boss is defeated on Floor 11, another Hidden Boss may appear again on Floor 12.

※ Mirror Dungeon cannot be progressed until the Hidden Boss Encounter is resolved. If the battle becomes too difficult due to accumulated Mounting Trials and Adversities, withdrawing from the Encounter may be a viable strategy.

※ The Mar. 12th EXTREME Mode update brings 4 Hidden Bosses encountered in the Mirror of Immortality EXTREME Mode. Additional updates on new Hidden Bosses will convert existing Hidden Bosses into EXTREME-exclusive Theme Pack Encounters.

Weekly Projection Cap

- Clearing Mirror Dungeon Exploration will yield additional Projection Rate.

- Clearing higher Floors with higher Adversity Scores will yield more Starlight and Projection Rate.

- You can earn up to 1,000 Projection Rate per week; any Projection Rate gained past 1,000 will be lost.

- The Weekly Projection Rate Cap's reset period is the same as the reset period for Weekly Bonuses.

※ Up to 60 levels' worth of Projection Rate can be obtained via completing Achievements. Any Projection Rate obtained via completing Achievements does not count toward the Weekly Projection Rate Cap.

※ If you find it difficult to clear the Achievements, you can gain weekly Projection Rate to obtain Projection Rate rewards instead.

※ Please note that playing through the Mirror Dungeon prior to the Mar. 12th Scheduled Update and claiming the rewards after the Mar. 12th Scheduled Update will not yield any Weekly Projection Rate Rewards.

Mirror Projection / Achievements

- You can gain Mirror Projection by clearing Mirror Dungeon achievements.

- Mirror Dungeon floors are counted as 'cleared' only when the player consumes Enkephalin Modules in the Reward Claim window. Please note this information before attempting to complete an Achievement tied to clearing the Mirror Dungeon.

- Please note that future updates will bring even more Achievements to the game.

- Please note that Mirror of Names and Spiders Achievements & Achievement Reward claims are available only until the update for the next new Mirror Dungeon.

- By meeting the Achievement conditions, you can still attain Achievements and increase Projection even if you clear the Mirror Dungeon with Rental Teams.

※ Please note that Rental Teams will be unable to attain forthcoming Team-related Achievements.

- Obtain various rewards based on your Mirror Projection level.

- Achievements to be added in the future will bring additional rewards.

QoL Improvements

With the Mirror of Names and Spiders EXTREME Mode update, the following improvements will be added to the game.

- A feature will be added to the “Fuse E.G.O Gift” screen, allowing you to immediately select all lower-tier E.G.O Gift materials owned for an E.G.O Gift Fusion.

- A feature will be added to allow E.G.O Gifts to be directly enhanced to “++” level.

- A filter function will be added to the E.G.O Gift Compendium to allow sorting by keywords, acquisition status, and other criteria.

- The sorting of E.G.O Gifts displayed in the Theme Pack Compendium will be improved.
