Ungien’s Circle Precious Chest Puzzle Guide

The Ungien's Circle Precious Chest puzzle in Genshin Impact is one of the more involved world puzzles introduced alongside the area’s expansion. Solving it grants you a Precious Chest that often contains a Frost Moon Seal, a key item for unlocking the Treasure Site at Ungien's Circle. For the latest Genshin Impact guides, make sure to bookmark our hub.

You’ll need to have completed the Pioneer Quest to unlock Ungien's Circle as a fast‑travel destination. Once that’s done, the puzzle becomes accessible and rewards you with both the Precious Chest and several extra loot opportunities afterward.

Step‑by‑Step Solution

Locate the Four Pioneer Source Structures

Fast travel to the Ungien's Circle southern Transit Station. Drop down toward the small circular eastern building. Next to it, you’ll find an Ancient Moon Pearl—interact with it to absorb Archaeolume Energy.

Revive the First Structure

Shoot Archaeolume Ripples at the Archaeolume Energy Barrier to open a passage. Enter the building, collect the chest inside, then absorb more Archaeolume Energy and fire at the Pioneer Source Structure to revive it.

Activate the Second and Third Structures

Move to the northeastern circular building. Absorb Energy and shoot at the chest inside to trigger the mechanic, reviving another Pioneer Source Structure and removing the laser. Walk in to collect the loot.

Repeat for the north‑eastern building—absorb Energy, shoot at its chest and the Pioneer Source Structure, and collect that chest.

Revive the Final Structure and Defeat the Enemy

Head to the middle big building. Revive the fourth Pioneer Source Structure using Archaeolume Ripples. Once all four structures are active, follow them—they’ll converge, spawning an enemy. Defeat it with a well‑built team to spawn the Precious Chest.

Collecting the Precious Chest gives you a Frost Moon Seal, required to unlock the Treasure Site.

Extra Chests After the Puzzle

Material Storage Chests

After completing the puzzle, activate the door mechanic in the middle building. Wait for the Pioneer Source Structure: Stasis Module to bring the Material Storage Chest inside. Open it, then take the lift up.

Common Chest Under the Elevator

Re‑enter the space from the side doors you unlocked earlier. Beneath the elevator platform, you’ll find a Common Chest—don’t miss it.

Exquisite Chest via Moon Pearl Launcher

Climb the first small circular building and use the Moon Pearl Launcher on its roof to shoot an Ancient Moon Pearl at the roof of the middle building. This yields an Exquisite Chest and a Lunoculus.

Western Side Chests

Explore the western area beyond the puzzle boundary to find two additional Common Chests.
