Immernachtreich Apokalypse Part 1 walkthrough – Genshin Impact Summertime Odyssey Fischl Mirage Chest & puzzle guide

The Golden Apple Archipelago is back for Genshin Impact's Summertime Odyssey event, which runs from July 15, 2022, to August 24, 2022. Various characters will have personalized Domains (also called Mirage) that you can clear once to loot a ton of Chests and learn more about their lore. Fischl's Mirage is the Immernachtreich Apokalypse, which is divided into three parts. In Part 1, you can loot three Chests and a Nightwatch Contract.

How to unlock the Immernachtreich Apokalypse Event Quest and Domain in Genshin Impact

You can unlock the Immernachtreich Apokalypse Event Quest after completing the following:

• The Golden Apple Vacation Returns!
• As the Courtyard in Spring Once Appeared (all three Parts of the Mirage)
• Blazin' Trails! (Event Quest only, the Mirage is optional)

After completing Blazin' Trails!, you will automatically get a prompt to change your in-game time to 6:00-24:00 of the next day and begin the Immernachtreich Apokalypse Event Quest. Much like Kazuha's segment, the Immernachtreich Apokalypse quest and Mirage are interconnected, so you'll need to complete all parts of Fischl's Domain to proceed with the rest of the event content.

All puzzle solutions and Chest locations in Immernachtreich Apokalypse Part 1

Before starting, reference the image above for two common terms used in this guide. The Gaze of the Deep is the primary puzzle mechanic across the Mirage. Meanwhile, the Elevator can be used to go up and down floors. If you left an Elevator upstairs or downstairs, step on the small platform on the side to summon it.

You need to adjust the camera angles to solve Gaze of the Deep puzzles. The directional angles need some approximating, but the camera zoom can be calculated by adjusting the zoom bar on the left. For example, if our instruction is "set the camera zoom to +4 of the minimum," we mean to set the zoom to the minimum, then click the plus sign four times.
