The Perilous Island is part of the temporary area in Genshin Impact. There is a chest near its shores that you can open after solving the fire and ice totem puzzle. 

You will notice a chest standing on a rock near the island. When you approach it, you will see two figures underwater, one on each side of the chest. To save you the trouble of trying to find the solution, we have already done it for you and are happy to share the results. Let's go!

How to Solve the Fire and Ice Totem Puzzle on the Perilous Island

You can tackle this puzzle after lighting up all three devices on the Golden Apple Archipelago. If you have already found this chest, then take a close look around. You will see two totems underwater: one depicting the Fire symbol and the other depicting the Ice symbol.

To open this exquisite chest, you need to activate both totems. Naturally, the Fire Totem can be activated with fire attacks, and the Ice Totem can be activated with ice attacks. 

Select a character with Cryo elemental abilities. Kaeya or Eula are good choices since they both have ground-based AoE Cryo attacks. 

A glowing ice symbol will appear above the Ice Totem when you activate it. The same principle applies to the Fire Totem. 

Now, choose a Pyro character. For example, Amber has a long-range fire attack, but you need to aim carefully from her bow to activate the totem. Otherwise, her arrows will land in the water and not reach the totem. 

If you don't have a Pyro archer, don't worry. Simply create a Hydro path with a Hydro character and quickly switch to Pyro. Run swiftly along the ice path and ignite the totem.

Congratulations, you have activated both totems and opened the chest on the Perilous Island. Approach it to open it and claim your reward.
