All Amphoreus Chests Mapped: Find Every Spirithief, Secret Elevator & Claim Celestial Ambrosia

Amphoreus is the fourth planet in Honkai: Star Rail and its maps hide a lot of treasure. This guide lists where treasure chests, Spirithiefs, and key puzzle items appear across Amphoreus so you can collect Celestial Ambrosia, level the Tides of the Basin in the Vortex of Genesis, and complete map-based objectives efficiently.

• How Amphoreus chest mechanics work, including Spirithiefs and the map counter.
• Chest locations for Okhema, Castrum Kremnos, Janusopolis, and the Vortex of Genesis.
• New areas added across versions 3.1–3.5 and specific notes for 3D rooms or puzzles.
• Notes on special Spirithiefs and hidden passages that affect chest access.

How Amphoreus treasure chests work

On Amphoreus, chests reward Celestial Ambrosia, which you can give to the Tides of the Basin in the Vortex of Genesis to earn progression rewards, such as Stellar Jade and Trailblazer’s Remembrance Eidolon items. In short, chests on Amphoreus are directly tied to basin progression.

Moreover, the in-map chest counter only tracks chests that are freely obtainable without finishing puzzles or defeating powered enemies. Also, Spirithiefs are a new Amphoreus mechanic: they can steal chests or other map objects. Often a Spirithief will flee when you try to pick up a chest, and sometimes it triggers an encounter. Consequently, most Spirithief events both grant a reward and lead to a chest, so they may be counted more than once by the tracker.

Finally, many Amphoreus maps use a dawn/evernight toggle that changes enemy and chest placement. Therefore, to collect everything you must sweep areas in both time settings. Also note that some rooms are 3D and require specific interactions or quests to reach all chests.

‘Eternal Holy City’ Okhema chest locations

Okhema is large, so it’s split into Marmoreal Palace (right side) and Marmoreal Market (left side). Sweep both F1 and F2 in dawn and evernight states to find all chests and Spirithiefs.

‘Bloodbathed Battlefront’ Castrum Kremnos chest locations

Casrtum Kremnos spans multiple floors and includes a few special cases. For example, a Spirithief in the hall before the 3D room on F1 does not appear as a chest; it activates when you try to pick up a nymph on the wall. That event gives rewards but not a chest. Also, a northern 3D room on B1 has a secret elevator that reveals four chests, which requires completing the side quest “I Once Was in Arcadia.”

‘Strife Ruins’ Castrum Kremnos chest locations

Strife Ruins also uses multiple floors and 3D spaces. Make sure to explore each floor in both time settings to trigger all scale and elevator mechanics, where present.

‘Abyss of Fate’ Janusopolis chest locations

Janusopolis features large 3D rooms and scale puzzles. In one northern 3D room on F2, you must place a sphere using a giant hand during dawn and then stand on the left scale to be lifted to the third floor. After you navigate the top floor, activate the lift to move between levels freely.

Vortex of Genesis chest locations

The Vortex of Genesis contains chests that directly feed the Tides of the Basin via Celestial Ambrosia. Leveling the basin yields progression rewards, so prioritize these chests if you want basin items.

‘Sanctum of Prophecy’ Janusopolis chest locations

Added in version 3.1, this area has many chests tied to the “Janus’ Maze” quest. These chests often don’t count toward the on-map chest counter. The maze quest unlocks from the northeast library area of F1 and is marked on the map with a blue symbol.

‘Murmuring Woods’ Grove of Epiphany treasure chests

Also added in 3.1, this multi-floor area includes Spirithiefs that sometimes steal objects other than chests — for example, a Spirithief on F2 steals a large rewindable block you need to clear a path. After defeating that Spirithief you can use the block to open the F1 door and collect the nearby chest.

‘Demigod Council’ Dawncloud treasure chests

Added in version 3.2, this long area includes a northern Spirithief that steals a floating scroll rather than a chest. Sweep the map thoroughly to find the scrolls and any hidden passages.

‘Dragonbone City’ Styxia treasure chests

Added in 3.2, Dragonbone City includes complex 3D rooms. On F1 use the controllable giant hand to break boxes and reveal paths. On F2, use hidden passage mechanisms to fully explore the room. Both floors require careful exploration with the spotlight and hand mechanics to reach all chests.

‘Fortress of Dome’ Eye of Twilight treasure chest locations

Added in version 3.3, this map includes Spirithiefs that sometimes steal hidden passages rather than chests. Explore B2, B1, F1, F2, and F3 and check for passage-related Spirithief events.

‘Fallen Twilight City’ Okhema treasure chest locations

Added in 3.3, Fallen Twilight City reuses Okhema layouts with some Spirithief changes. For example, a Spirithief by the teleporter on eF1 activates from interaction with a small chimera rather than a chest.

‘Lightless Chapel’ Dawncloud treasure chest locations

Also added in 3.3, the Lightless Chapel contains Spirithiefs that steal a floating scroll, elite enemies, and even another Spirithief. Follow map markers and clear both dawn and evernight states for full coverage.

‘Cloudedge Bastion Ruins’ Eye of Twilight treasure chest locations

Added in 3.3, this map uses a compass to create paths. Because the compass path changes, floating center chests are typically accessed by using the compass mechanics from the main story. Some Spirithiefs steal nymphs or hidden passages on various floors.

‘Aedes Elysiae’ treasure chest locations

Added in version 3.4, Aedes Elysiae contains straightforward chests without complex puzzles or large 3D rooms. Sweep the area normally to find all chests.

‘Warbling Shores’ Styxia treasure chest locations

Added in version 3.5, Warbling Shores includes visible Spirithiefs that aren’t always hidden behind chests. The top-left Spirithief sits in plain sight, while one near the central platform is already concealed with its coin showing. Also, repeating southern puzzles can yield many chests, though those repeats may not count toward the map counter.

Quick tips

• Scan both dawn and evernight on each floor — many chests only appear in one setting.
• Watch for Spirithiefs; they may steal chests, blocks, scrolls, elite enemies, or hidden passages.
• Complete related side quests (for example, “I Once Was in Arcadia”) to unlock secret elevators or extra chests.
• Prioritize Vortex chests if you need basin progression rewards like Stellar Jade.
