How to solve the Guiding Light Mirror puzzle northeast of the Three Realms Gateway Offering in Genshin Impact

The Three Realms Gateway Offering is a 40-day event that runs from Feb. 17, 2022, to Mar. 30, 2022. Within this limited-time version of Enkanomiya, you can play through an array of new puzzles unique to the Three Realms Gateway Offering.

In the northeast of the region, where the Evernight Temple would normally be, you'll find a new two-part puzzle that involves switching and rotating Mirrors between Cryo and Hydro states in order to guide light to its designated location. To prepare, bring a Cryo and Pyro applicator—archers are the easiest to use.

Start by heading to the clearing circled in the image above. You'll find four Mirrors and a glowing mechanism. The glowing mechanism can be activated using the Bokuso Box. Upon activation, it will shoot out a beam of light that will be guided by the Mirrors, with the goal of lighting up floating stones in the area.

How to Solve the Puzzle

Assuming that the glowing mechanism is behind you and the puzzle is in its original state, follow these steps to solve it:

• Step one: Apply Pyro to Mirror #1.
• Step two: Apply Pyro to Mirror #3.
• Step three: Activate the Bokuso Box beside the glowing mechanism.

This will guide the light to the floating stone in front, completing the first part of the puzzle. You'll be rewarded with an Exquisite Chest. Without tampering with the puzzle, proceed by doing the following:

• Step one: Rotate Mirror #4 three times.
• Step two: Apply Cryo to Mirror #3.
• Step three: Activate the Bokuso Box beside the glowing mechanism.

This will guide the light to the floating stone on the right, completing the second half of the puzzle. You'll be rewarded with a Precious Chest.
