How do I unlock the hidden domain in Yashiori Island in Genshin Impact?

To unlock the hidden domain in Yashiori Island in Genshin Impact, you need to complete a series of tasks that involve solving puzzles and interacting with the environment. The domain is called the "Moshiri Kara" domain, and it is located on the northeastern part of Yashiori Island. The process to unlock it is tied to the "Moshiri Ceremony" world quest, which involves several steps and requires careful attention to detail. Here is a detailed guide to help you through the process.

First, you need to start the "Moshiri Ceremony" quest. This quest is given by an NPC named Kama near the Fort Fujitou area on Yashiori Island. Kama will ask you to investigate the strange phenomena happening around the island, which involves dealing with the Balethunder effect and solving puzzles. The Balethunder effect is a unique environmental hazard in Yashiori Island that continuously drains your characters' HP unless you have a way to mitigate it. To deal with this, you can use characters like Barbara or Qiqi who can provide consistent healing, or you can use the Electrogranum from the nearby Statue of the Seven to protect yourself from the Balethunder.

Once you have accepted the quest, Kama will guide you to several locations where you need to interact with Electro pillars and solve puzzles. The first step is to activate three Electro pillars near the quest marker. These pillars are scattered around the area, and you need to use an Electro character like Fischl, Keqing, or the Traveler (Electro) to activate them. After activating all three pillars, a cutscene will trigger, and a new area will open up.

Next, you need to head to the newly revealed area and interact with the large stone slab. This will start a puzzle where you need to rotate the stone slabs to match the pattern shown on the ground. The puzzle involves rotating the slabs in a specific order to align the symbols correctly. If you make a mistake, you can reset the puzzle by interacting with the central mechanism. Once the puzzle is solved, a chest will appear, and you will need to defeat a group of enemies that spawn nearby.

After defeating the enemies, you will need to interact with the stone slab again to reveal the entrance to the Moshiri Kara domain. However, before you can enter the domain, you need to complete one final task. Kama will ask you to collect three "Moshiri Kara" items that are scattered around the area. These items are hidden in small caves and require you to solve minor puzzles or defeat enemies to obtain them. Once you have collected all three items, return to Kama to complete the quest and unlock the domain.

When entering the domain, it is important to have a well-balanced team that can handle both combat and puzzle-solving. A recommended team composition includes a main DPS character like Diluc or Ganyu, a sub-DPS character like Fischl or Xingqiu, a healer like Barbara or Bennett, and a support character like Venti or Sucrose for crowd control. This team will allow you to deal with the enemies inside the domain while also providing the necessary utility to solve any puzzles you encounter.

For artifacts and weapons, focus on maximizing your DPS characters' damage output. For example, Diluc benefits greatly from the Crimson Witch of Flames artifact set, which increases Pyro damage and enhances elemental reactions. Ganyu, on the other hand, works well with the Blizzard Strayer set, which boosts Cryo damage and increases critical rate against frozen enemies. For weapons, prioritize those with high base attack and useful secondary stats, such as the Wolf's Gravestone for Diluc or the Amos' Bow for Ganyu.

One common mistake to avoid is neglecting the Balethunder effect. If you do not have a way to mitigate the continuous HP drain, your characters will quickly fall in battle. Always make sure to have a healer or the Electrogranum active when exploring Yashiori Island. Additionally, do not rush through the puzzles. Take your time to observe the patterns and think through the solutions to avoid unnecessary mistakes.

Advanced techniques include using elemental reactions to your advantage. For example, combining Hydro and Electro attacks can create the Electro-Charged reaction, which deals continuous damage to enemies. Similarly, using Cryo and Electro attacks can trigger the Superconduct reaction, which reduces the enemy's physical resistance and makes them easier to defeat. These reactions can be particularly useful in the Moshiri Kara domain, where you will face multiple waves of enemies.

In summary, unlocking the hidden domain in Yashiori Island requires completing the "Moshiri Ceremony" quest, solving puzzles, and dealing with the Balethunder effect. By following the steps outlined above and using a well-balanced team with optimized artifacts and weapons, you can successfully unlock the Moshiri Kara domain and reap the rewards it offers. Remember to take your time, pay attention to the environment, and use elemental reactions to your advantage to make the process smoother and more enjoyable.
