In Genshin Impact, invisible torches in Panjwahe Ruins are part of a puzzle that allows you to remove the blue barrier, unlock the elevator and get into secret room. By solving these riddles, you can get treasure chests. In this guide, we'll tell you where the puzzle is and what you need to do to solve it.
Solving the puzzle with torches and a barrier in the ruins of Panjwahe
Location of the puzzle with phantom torches
It can be found in an underground location, which can be accessed by completing the “Dirge of Bilcis” questline. Travel to the underground teleportation point shown in the screenshots below, and then go to the ruins, the entrance to which can be seen ahead.
Going inside you will find a giant prism surrounded by four phantom torches. This is where the puzzle begins. The first step is to make the torches visible.
How to light phantom torches
Upon entering the temple, immediately turn right and pick up the primordial luminary (glowing triangle). Now go to the other side and place the pyramid on the blue platform near which you can find Chronicles of the Ancient Oasis II. This will result in a cell of truth.
Interact with the spawned device. A glowing orange diamond will appear above your character's head. Now approach the four ghostly torches to make them visible again. The screenshots below show their location. You can immediately activate them with Pyro attacks. Note that if the effect of the cell of truth disappears, then simply touch it again to recharge.
When you light all the torches, a normal chest will appear near the blue barrier, and the red barrier will disappear from the pedestal (pedestal with a book) . Interact with the console (requires Power level 4 at the Red Sands Plate) to remove the barrier and access the lift.
Fight the Ruin Thresher
Now sit in the elevator and go down. There you will find a deactivated Ruin Thresher. As soon as you approach him, he will attack you. Recall that this enemy is resistant to physical attacks, so we recommend that you deal elemental damage to him, creating various reactions. Don't forget to also hit his weak spots on his legs.
Having dealt with the robot, do not wait for a break, as you will immediately be attacked by two primordial structures. Electro and Dendro attacks work best against them, as they prevent them from becoming invisible and stun them. Destroying the last enemies will give you a rich chest.
How to get to the secret room
Return to the elevator and select a Pyro archer, such as Eimiya or Ember. Then lift the camera up – you should see a crack on the back wall, covered with vines. Shoot it with Aimed Shooting to burn the vines. Now start climbing up and crawl through this hole.
You will end up in a secret room with Stone stove IV (reading requires a fully upgraded Lilupar genie's magic lamp) and a regular chest. This concludes the solution of the puzzle.
