🌙 What Are Evermoon Seals?

Evermoon Seals are collectible items tied to the Nod-Krai region. Each island has its own set of seals, and you’ll need three from the same island to open that island’s Evermoon Treasure Vault. On Hiisi Island, this means gathering three Hiisi Seals to break the barrier on the vault entrance.

🗺 How to Get Hiisi Island Evermoon Seals

• Chest Rewards – Evermoon Seals drop from high-tier chests like Precious and Luxurious Chests scattered across Hiisi Island.

• World Challenges – Defeat elite enemies or complete puzzles that unlock guarded chests for a chance at seals.

• Quest Completion – Certain local quests may also reward seals.

Since the drop pool is shared across these chest types, it’s a matter of persistence—clear as many chests on Hiisi Island as possible until you have three seals.

📍 Treasure Vault Location (Hiisi Island)

To find the vault:

1. Start from the southeastern teleport waypoint above the Statue of the New Moon.

2. Head southeast until you reach the cliff edge.

3. Descend carefully along the cliffside until you spot a cave opening.

4. Inside, you’ll find the sealed vault door. Interact with it, spend your three Hiisi Seals, and the barrier will drop.

🎁 Rewards Inside the Vault

Opening the vault will reward you with:

• High-tier artifacts

• Rare upgrade materials

• Special regional loot such as Dust of Enlightenment

• A large amount of Mora and Adventure EXP

These vaults are some of the most rewarding single-chest events in the region.

⚡ Tips for Farming Seals

• Sweep daily routes on Hiisi Island for Precious and Luxurious Chests.

• Clear elite enemies whenever you encounter them—they often guard chests with higher drop chances.

• Focus exploration around cliffs, hidden caves, and puzzle areas; these spots are most likely to house seal-dropping chests.
