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 east of the area where The Serpent’s Heart normally would be, you’ll find a Guiding Light Mirror puzzle. The objective is to guide the light from the glowing mechanism to the floating stone. Start by heading to the area circled in the image below.

You need to bring a character that can apply Pyro with you to complete the puzzle. If you already started tinkering with the rotations, reference the image below for a visual guide of what the final puzzle should look like. Otherwise, read on to find out how to solve it from scratch.

Assuming you have not moved anything, follow the steps below to complete the puzzle. They can be done in any order.

  • Step one: Apply Pyro to Mirror #1. Step two: Rotate Mirror #1 once. Step three: Apply Pyro to Mirror #2.

Once those are done, use the Bokuso Box beside the glowing mechanism to release a beam of light that the Mirrors will guide to the floating stone, completing the puzzle. You’ll be rewarded with a Common Chest.
