How do I unlock the hidden chest in the Tianqiu Valley in Genshin Impact?

To unlock the hidden chest in Tianqiu Valley in Genshin Impact, you need to complete a specific puzzle involving three towers. This puzzle is part of the "Tianqiu Treasure Trail" quest, which is triggered when you interact with a stone tablet in the area. The puzzle requires you to light up three towers by solving combat challenges and activating mechanisms. Here is a detailed guide to help you complete this task.

First, locate the stone tablet in Tianqiu Valley. It is found near the center of the area, close to a large stone structure. Interacting with the tablet will start the quest and reveal the three towers you need to activate. Each tower has its own challenge, and you must complete them in a specific order. The challenges involve defeating enemies within a time limit and activating mechanisms.

The first tower is located to the east of the stone tablet. When you approach it, you will trigger a combat challenge. You need to defeat a group of enemies, including Hilichurls and an Abyss Mage, within a time limit of 60 seconds. To make this easier, use characters with strong AoE (Area of Effect) abilities, such as Diluc, Klee, or Xiangling. These characters can quickly clear groups of enemies. Make sure to dodge attacks and use elemental reactions like Vaporize or Melt to maximize damage. After defeating the enemies, interact with the mechanism to light up the first tower.

The second tower is to the west of the stone tablet. This challenge involves activating a mechanism while defending it from waves of enemies. You need to protect the mechanism from being destroyed while also defeating all enemies within the time limit. Use characters with strong crowd control abilities, such as Venti or Sucrose, to group enemies together and make them easier to defeat. Characters with shields, like Zhongli or Noelle, can also help protect the mechanism. Focus on defeating the enemies quickly while keeping an eye on the mechanism's health. Once the enemies are defeated, interact with the mechanism to light up the second tower.

The third tower is to the north of the stone tablet. This challenge requires you to solve a puzzle involving pressure plates. You need to step on the correct sequence of pressure plates to activate the mechanism. The correct sequence is indicated by the glowing symbols on the plates. Step on the plates in the order of the symbols to complete the puzzle. If you make a mistake, the puzzle will reset, and you will need to start over. Take your time and carefully follow the sequence to avoid mistakes. Once the puzzle is solved, interact with the mechanism to light up the third tower.

After lighting up all three towers, a hidden chest will appear near the stone tablet. Open the chest to receive your rewards, which include Primogems, Mora, and other valuable items. This chest is part of the "Tianqiu Treasure Trail" quest, so make sure to complete the quest to fully unlock the chest.

Here are some important tips and considerations to keep in mind while completing this puzzle. First, make sure your characters are well-leveled and equipped with appropriate artifacts and weapons. This will make the combat challenges easier to complete. Second, pay attention to the time limits and focus on defeating enemies quickly. Use elemental reactions to maximize damage and clear enemies faster. Third, take your time with the pressure plate puzzle and carefully follow the sequence to avoid mistakes.

Common mistakes to avoid include not paying attention to the time limits, which can cause you to fail the combat challenges. Also, avoid stepping on the wrong pressure plates in the puzzle, as this will reset the sequence and force you to start over. Make sure to use characters with strong AoE abilities and crowd control to make the combat challenges easier.

For team composition, consider using characters like Diluc, Klee, Xiangling, Venti, Sucrose, Zhongli, and Noelle. These characters have strong AoE abilities, crowd control, and shields, which will help you complete the challenges more easily. For artifacts, focus on increasing attack, elemental mastery, and critical rate to maximize damage. Weapons with high base attack and useful passives, such as the Wolf's Gravestone or the Skyward Atlas, are also recommended.

In summary, unlocking the hidden chest in Tianqiu Valley involves completing a series of challenges, including combat and puzzles. Use strong characters with AoE abilities and crowd control, pay attention to time limits, and carefully follow the pressure plate sequence. With the right strategy and preparation, you can successfully unlock the hidden chest and claim your rewards.
