The Evermoon Seal is a Nod-Krai precious item in Genshin Impact, which can be used to open Treasure Vaults. The item works like an Obsidian Ring and can only be found inside Precious chests in Genshin Impact. Here’s how players can find Hiisi Island Evermoon Seal and Treasure Vault Locations in Genshin Impact.
Hiisi Island Evermoon Seal Locations In Genshin Impact
There are three Evermoon Seals to locate on Hiisi Island in Genshin Impact. The first two can be collected from random Precious chests during the For a Green Island quest and The Mirrors, the Maze, and the Tsar quest, while the third one will be obtained from a random Precious chest on Hiisi Island.
For a Green Island Quest In Genshin Impact
Hiisi Island Precious Chest Locations #1-4
To initiate the For a Green Island quest in Genshin Impact, players need to teleport to Thunderclap Reef’s northeastern waypoint, then walk west towards the water between the mountains. Verna will tell Travelers what to do:
- Head inside the cave.
- Grab the first Fragment and shoot it towards the rotating rocks.
- Use the Kuuhenki Energy to pull the stairs for the small robots.
- Interact with the robots and follow them to the obstacle.
- Ask them to combine and remove the obstacle in the way.
- Collect the Exquisite chest in Genshin Impact.
- Grab the second Fragment.
- Follow them outside.
- Throw the Fragment towards the rocks.
- Talk to Verna.
- Use the spawned Moonlane to reach the top of Thunderclap Reef.
- Defeat the attacking enemy.
- Collect the Precious Chest.
- Locate three Kuuhenki to activate the Moon Mirror.
During this step, players must head to Thunderclap Reef’s northern shore to locate one of the Kuuhenkis, where they will find a Radiant Beast. Defeat it and collect the unlocked Precious Chest next to it. Next, if players wish to complete the For a Green Island quest, they need to do the following:
- Solve the Moon Mirror puzzle in Genshin Impact by moving the statue through the mirror until it faces the one in the right mirror.
- Collect the Precious Chest.
- Throw the Fragments toward the rotating rocks, one at a time.
- Collect the Luxurious chest and Lunoculus.
Afterward, move to the southern shore to collect one more Precious chest in Genshin Impact.

- Destroy the obstacle by placing a Lakkaberry for the Rock Crab to destroy it (If players don’t own one, they can find a few in the cave.)
