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 related to the island's unique mechanics and questline. The hidden domain is called the Moshiri Kara domain, and it is tied to the "A Particularly Particular Author" world quest. This quest is part of the larger Tsurumi Island storyline, which involves solving puzzles, interacting with the environment, and dealing with the island's fog mechanics. Here is a detailed guide on how to unlock the domain.

First, you need to start the "A Particularly Particular Author" quest. This quest becomes available after completing the "Through the Mists" questline, which is the main storyline for Tsurumi Island. The "Through the Mists" questline involves multiple days of exploration and interaction with the island's fog, so make sure you have completed it before attempting to unlock the hidden domain. Once you have finished the "Through the Mists" questline, you can find the "A Particularly Particular Author" quest by speaking to Sumida in Inazuma City. She will ask you to investigate Tsurumi Island further, which leads you to the hidden domain.

The next step is to head to Tsurumi Island and locate the Moshiri Kara domain entrance. The domain is located on the southern part of the island, near the coast. However, the entrance is initially blocked by a large rock formation. To remove the blockage, you need to solve a puzzle involving three Electro Seelies. These Seelies are scattered around the area, and you need to guide them back to their respective pedestals. Each Seelie is guarded by enemies, so be prepared for combat. Once all three Seelies are in place, the rock formation will disappear, revealing the entrance to the domain.

When solving the Seelie puzzle, it is important to note that the fog on Tsurumi Island can make navigation difficult. The fog reduces visibility and can cause you to lose your way if you are not careful. To mitigate this, make sure to activate the nearby Statue of the Seven and any Teleport Waypoints you come across. This will make it easier to navigate the island and return to the domain entrance if needed. Additionally, using characters with abilities that can reveal the environment, such as Amber's Baron Bunny or Sayu's elemental skill, can help you navigate the fog more effectively.

Once the domain entrance is revealed, you can enter the Moshiri Kara domain. Inside, you will encounter a series of challenges, including combat encounters and environmental puzzles. The domain is designed to test your combat skills and puzzle-solving abilities, so make sure your team is well-prepared. A balanced team composition is recommended, with at least one DPS character, one healer, and one support character. Characters like Hu Tao, Ganyu, or Ayaka are excellent choices for DPS, while Bennett or Jean can provide healing and support. For the puzzles, having a character with an Electro vision, such as Raiden Shogun or Fischl, can be helpful, as some puzzles require Electro abilities to solve.

In terms of artifacts and weapons, prioritize building your DPS character with high damage output. For example, if you are using Hu Tao, equip her with the Crimson Witch of Flames artifact set and a weapon like the Staff of Homa or Dragon's Bane. For support characters, focus on artifacts that enhance their healing or energy recharge, such as the Noblesse Oblige set for Bennett. Weapons like the Favonius Sword or Sacrificial Sword can help with energy management, ensuring your team can use their elemental bursts frequently.

One common mistake to avoid is rushing through the domain without paying attention to the puzzles. Some puzzles require careful observation and timing, so take your time to understand the mechanics before attempting to solve them. Additionally, make sure to bring plenty of healing items and food buffs, as the combat encounters can be challenging, especially if you are under-leveled or under-geared.

Advanced techniques for optimizing your run include using elemental reactions to your advantage. For example, combining Hydro and Electro abilities can trigger the Electro-Charged reaction, which deals continuous damage to enemies. Similarly, using Cryo and Electro abilities can trigger the Superconduct reaction, which reduces enemy defense. These reactions can significantly increase your damage output and make the combat encounters easier to manage.

In summary, unlocking the hidden domain in Tsurumi Island requires completing the "A Particularly Particular Author" quest, solving the Seelie puzzle, and navigating the island's fog. A well-balanced team, proper artifact and weapon setups, and careful attention to puzzle mechanics are key to successfully unlocking and completing the domain. By following these steps and tips, you can efficiently unlock the Moshiri Kara domain and reap the rewards it offers.
