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 cloaked in darkness, you can play through an array of new puzzles unique to the Three Realms Gateway Offering.
A new puzzle mechanic is the Guiding Light Mirror puzzle, which involves guiding a beam of light from one mechanism to another with the help of Cryo and Hydro Mirrors. You'll find one such puzzle in the southeast of the western area of the Three Realms Offering Gateway, where The Narrows would normally be.
Head to the area circled in the image above to find the puzzle. You need to bring a character that can apply Cryo. Once you get there, you'll find two Hydro Mirrors and a glowing mechanism. If you already started tinkering with the puzzle, reference the image below for a visual guideline of what the final arrangement should look like.
If you're starting from scratch, follow the steps below to solve the puzzle. They can be done in any order.
- Step one: Rotate Mirror #1 once.
- Step two: Apply Cryo to Mirror #2.
After completing the steps above, use the Bokuso Box beside the glowing mechanism to prompt it to shoot a beam of light. The Mirrors will direct it toward the floating stone, completing the puzzle. You'll be rewarded an Exquisite Chest for your effort.
