Summary

    • The Evermoon Seals on Hiisi Island unlock special Lunar Treasures when you collect three of the same symbol.
    • Some vaults still hide behind puzzles or unnoticeable spots, which encourage exploration with each Genshin Impact 6.0 update.

Hiisi Island is one of the new islands in Nod-Krai, it was added during the Version Luna I (5.5). This island is connected to the lore of the Frostmoon Scions, who are a group that appears in Nod-Krai. Additionally, One of the new exploration mechanics is the Lunar Treasury or Evermoon Vaults. In this Genshin Impact Hiisi Island guide, we’ll help you locate Evermoon Seala to unlock the vaults and earn rewards. 

Genshin Impact Hiisi Island: The New Island in Nod-Krai

The Genshin Impact Hiisi Island is part of Nod-Krai alongside Lempo Isle and Paha Isle. It is home to the Frostmoon Scions, a group connected to the Frost Moon myth in Nod-Krai. In this island, players can explore as part of exploration rewards in Version Luna I. 

Because Hiisi Island is new, some players believe there are vaults or Evermoon Seal spots specifically on it. However, detailed locations are “to be updated” as the game continues. 

What Are Evermoon Seals?

Evermoon Seals are a new item in Nod-Krai. They have similar usage to the Obsidian Fragments from Natlan, in that you must collect pieces with the same marking (symbol) to form a full seal. Each seal acts like a key, and once you have three matching ones, you can use them to unlock a Vault or Lunar Treasury in that same region. 

How to Find Evermoon Seals & Vaults in Genshin Impact Hiisi Island

You can find Evermoon Seals across Hiisi Island, Lempo Isle, and other sub-areas. They are usually in hard-to-reach places such as cliffs, small caves, or behind waterfalls. Once you collect three seals with the same symbol, you can open a matching Lunar Treasury, also known as an Evermoon Vault.

Notes

Where to Find

Evermoon Seals randomly drop from exploring Nod-Krai; on islands like Lempo Island, cliffs, near landmarks. 

There is no full map yet of the exact spawn points on Hiisi Island. Locations of all vaults are still in discovery. 

Matching Markings

You must collect three seals with the same symbol/marking to activate a vault. 

It’s unclear if you can reuse or trade markings; whether there are “duplicate safe zones.”

Unlocking Vaults

Once you have 3 matching Evermoon Seals, you can unseal a Lunar Treasury in that subregion, which holds rewards. 

Whether vaults have puzzles or timed conditions (night/day); there is not confirmation yet.

Rewards

One expected reward is the Sanctifying Elixir, similar to what Obsidian Fragments yield in Natlan. 

The full list of vault rewards are not out yet. Might include Primogems, artifacts, or special lore items.

Although we already know how seals work in general, the exact layout of Hiisi Island and the kinds of prizes hidden in every vault remain unknown. With this, it lets players have fresh discoveries with each update, and give explorers more reasons to revisit Nod-Krai’s hidden corners.

Tips for Collecting Seals & Unlocking Vaults in Genshin Impact Hiisi Island

    • Explore every corner of Nod-Krai: Observe edges of cliffs, caves, high land, and below waterfalls. The seals tend to appear in less-noticable spots.
    • Pay attention to seal markings. Once you get a seal, note its symbol, since only matching ones count to unlock a vault.
    • Use teleport waypoints to have a fast travel and explore the island more efficiently, especially in Lempo Isle. 
    • Finish exploration missions on Hiisi Island; Once you finish the exploration missions, you will get primogen awards which eventually help your progression.
    • Use Characters Wisely: Explore with characters who have good mobility and exploration utility to reach hard spots with platforms or climbing.

Significance of Genshin Impact Hiisi Island System

The seals and vaults have connections to the Frostmoon Scions and the myths in Nod-Krai. With that, players should explore to find out more about worldbuilding. Players who enjoy exploring can earn meaningful items like Sanctifying Elixir or other loot from explorations.

Also, the mechanics of matching marks to unlock vaults gives a new set of challenges for the travelers to be invested on. Since the locations are not yet out, HoYoverse has room to add updates, map markers, and more vaults over time.

Final Thoughts

The new Genshin Impact Hiisi Island, along with the Evermoon Seals & Vaults let players enjoy fresh and rewarding content. In essence, the system encourages travellers to explore the region, collect three matching seals, and unlock hidden vaults. Additionally, you can earn rewards like Sanctifying Elixir, uncover lore, and primogems. Although full details, especially for Hiisi Island, are still unknown, the mechanics are confirmed and can be started already.
