Where is the shrine that requires a specific treasure chest to be opened to unlock in The Legend of Zelda: Breath of the Wild?

The shrine you are referring to is the "Tahno O'ah Shrine," which is located in the Lanayru region of Hyrule. This shrine is unique because it requires you to open a specific treasure chest to unlock it. The treasure chest is hidden underwater, and you need to use the Cryonis rune to access it. Here is a detailed guide on how to find and unlock this shrine.

To begin, you need to travel to the Lanayru region, specifically to the area near the Lanayru Road - East Gate. The shrine is located in a small pond just east of the gate. When you arrive at the pond, you will notice that the shrine is not immediately visible. This is because the shrine is hidden and will only appear once you open the specific treasure chest.

The first step is to use your Sheikah Sensor to detect the treasure chest. If you have not already done so, you can set your Sheikah Sensor to detect treasure chests by speaking to Purah at the Hateno Ancient Tech Lab. Once your sensor is set to detect treasure chests, it will start beeping as you approach the pond. This indicates that the chest is nearby.

Next, you need to locate the treasure chest. The chest is submerged underwater in the pond. To access it, you will need to use the Cryonis rune, which allows you to create ice blocks from water. Stand near the edge of the pond and use the Cryonis rune to create an ice block in the water. Climb onto the ice block and look down into the water. You should be able to see the treasure chest beneath the surface.

Now, you need to use the Cryonis rune again to lift the treasure chest out of the water. Position yourself directly above the chest and create another ice block. This will cause the chest to rise to the surface. Once the chest is on the surface, you can open it to reveal a Ruby. As soon as you open the chest, the Tahno O'ah Shrine will emerge from the ground nearby.

It is important to note that you must open the specific treasure chest in the pond to unlock the shrine. If you open any other chest, the shrine will not appear. This is why it is crucial to use the Sheikah Sensor to ensure you are targeting the correct chest.

One common mistake players make is not using the Cryonis rune correctly. If you do not position the ice block directly above the chest, it may not lift the chest out of the water. Make sure to take your time and align the ice block properly. Additionally, some players may overlook the importance of setting the Sheikah Sensor to detect treasure chests. Without this, it can be difficult to locate the chest in the pond.

In terms of preparation, you do not need any special items or equipment to unlock this shrine. However, having a good supply of stamina can be helpful, as you may need to swim or climb to reach the pond. If you have the Zora Armor, it can make swimming easier and faster.

An alternative approach to finding the shrine is to explore the area thoroughly and look for clues. The pond is relatively small, so it should not take long to locate the treasure chest. If you are having trouble finding the chest, try using the Magnesis rune to scan the area for metal objects. This can help you pinpoint the chest's location.

In summary, the Tahno O'ah Shrine is unlocked by opening a specific treasure chest submerged in a pond near the Lanayru Road - East Gate. Use the Cryonis rune to lift the chest out of the water and open it to reveal a Ruby. Once the chest is opened, the shrine will appear. Make sure to use the Sheikah Sensor to detect the chest and position the ice block correctly. With these steps, you should be able to unlock the shrine and earn a Spirit Orb.
