How to solve the Guiding Light Mirror Puzzle in the ruin south of The Narrows — 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 cloaked in darkness, you can play through an array of new puzzles unique to the Three Realms Gateway Offering.

South of what would normally be The Narrows (west of the Dainichi Mikoshi), you'll find an entrance to a ruin that houses a Guiding Light Mirror puzzle. Start by heading to the area circled in the image below. The location is quite obscure—once you reach the edge of the cliff, jump down to find the entrance to the ruin.

Upon entering the narrow entrance, you'll encounter a Seelie. Let it guide you deeper into the ruin. Once it stops at a dead-end, use an archer to shoot at the Exploding Barrels to create a hole in the wall. The Seelie will guide you to a Torch, which you can light up with Pyro.

The other two Torches are located on the same platform as the Guiding Light Mirror puzzle. Light them up to obtain a Common Chest.

Meanwhile, reference the image above for a visual guideline of what the final arrangement of the Guiding Light Mirror puzzle should look like. If you haven't tinkered with the puzzle at all, follow the steps below in any order to solve it:

• Step one: Apply Hydro to Mirror #1.
• Step two: Rotate Mirror #1 twice.
• Step three: Apply Cryo to Mirror #2.
• Step four: Rotate Mirror #3 once.

Once that's done, use the Bokuso Box beside the glowing mechanism to propel a beam of light forward, which the Mirrors will guide to the floating stone. You'll be rewarded with a Precious Chest for your effort.

Solving this puzzle will also unlock the Cryo Monument in front of the locked gate on the left. Apply Cryo to it and let the Seelie guide you to the next room. There, apply Cryo to the second Monument and loot the Common Chest shrouded in darkness using the Bokuso Box.

This should allow you to exit the ruin. Outside, you'll find an Enkanomiya Phase Gate that will move you upward to the location of the Seelie Post. Once the Seelie lands on it, you'll be rewarded with another Common Chest.
