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

To unlock the hidden domain in Tsurumi Island in Genshin Impact, you need to complete a series of tasks that are part of the "Through the Mists" world questline. This questline is essential for unlocking the domain, as it involves clearing the persistent fog that covers the island and solving various puzzles. Here is a detailed guide to help you through the process.

First, you need to start the "Through the Mists" questline. This quest becomes available after you have completed the "Seirai Stormchasers" quest and have reached Adventure Rank 30 or higher. To begin, head to the Adventurers' Guild in Inazuma City and speak with Katheryne. She will direct you to Tsurumi Island, where you will meet a character named Ruu. Ruu will guide you through the initial steps of the questline, which involve interacting with various objects and NPCs on the island.

The main mechanic involved in this questline is the use of the Peculiar Pinion gadget. This gadget is essential for interacting with the Thunderbird statues scattered across Tsurumi Island. You will receive the Peculiar Pinion during the questline, and it allows you to reveal hidden objects and activate mechanisms that are otherwise invisible. Make sure to equip the Peculiar Pinion in your gadget slot, as you will need to use it frequently.

The first major task is to clear the fog from Tsurumi Island. This involves completing a series of sub-quests that require you to interact with Thunderbird statues and solve puzzles. Each sub-quest will guide you to a different part of the island, where you will need to use the Peculiar Pinion to reveal hidden mechanisms and activate them. These mechanisms often involve aligning symbols or activating elemental totems, so be prepared to use characters with different elemental abilities.

One important tip is to bring a well-rounded team that can handle various elemental reactions. A team with Pyro, Electro, and Anemo characters is recommended, as these elements are often required to solve puzzles and defeat enemies. For example, a team consisting of Diluc or Hu Tao for Pyro, Fischl or Raiden Shogun for Electro, and Venti or Sucrose for Anemo can be very effective. Additionally, having a healer like Bennett or Jean can help sustain your team during combat encounters.

As you progress through the questline, you will encounter several combat scenarios. These battles can be challenging, so make sure your characters are well-equipped with appropriate artifacts and weapons. For DPS characters, artifacts like Crimson Witch of Flames for Pyro characters or Thundering Fury for Electro characters are ideal. For support characters, Noblesse Oblige or Viridescent Venerer sets can provide valuable buffs and debuffs. Weapons should be chosen based on the character's role, with a focus on increasing attack power, elemental mastery, or energy recharge.

Once you have completed the "Through the Mists" questline and cleared the fog from Tsurumi Island, the hidden domain, known as the Moshiri Kara domain, will become accessible. The domain is located in the northeastern part of the island, near the Moshiri Ceremonial Site. To unlock the domain, you will need to solve a final puzzle involving Thunderbird statues and the Peculiar Pinion. Use the gadget to reveal hidden mechanisms and activate them in the correct order to unlock the domain.

A common mistake to avoid is rushing through the questline without paying attention to the details. The puzzles and mechanisms on Tsurumi Island can be complex, and missing a step can lead to confusion and delays. Take your time to explore each area thoroughly and interact with all available objects. Additionally, make sure to keep your team's health and energy levels high, as some combat encounters can be unexpectedly difficult.

Advanced techniques include using elemental reactions to your advantage during combat and puzzle-solving. For example, using Electro-Charged reactions can deal continuous damage to enemies, while Overloaded reactions can break through shields. In puzzles, combining elements like Pyro and Electro can activate multiple mechanisms simultaneously, saving time and effort.

In summary, unlocking the hidden domain in Tsurumi Island requires completing the "Through the Mists" questline, using the Peculiar Pinion gadget, and solving various puzzles and combat scenarios. A well-rounded team with strong elemental synergy, appropriate artifacts, and weapons is essential for success. Take your time to explore and interact with the environment, and use elemental reactions to your advantage. By following these steps and tips, you will be able to unlock the Moshiri Kara domain and continue your exploration of Tsurumi Island.
