Unveiling the Treasure Chest Locations and Map in Honkai: Star Rail’s Amphoreus

Amphoreus is the fourth planet in Honkai: Star Rail that you’ll visit. Just like all the other areas, it’s filled with loot. You’ll need to scour the maps out completely to get some exclusive rewards, so to help you hunt them down, we’ve compiled the maps and loot locations in our guide.

Most maps have loot hidden around and this loot expands beyond just treasure chests. When you open the map, you’ll notice a chest icon in the top left corner with numbers next to it. This indicates how many of the different types of loot you’ve found. However, this counter only lists treasure that isn’t locked behind puzzles or formidable foes (the powerful monsters that guard chests), as well as Spirithiefs, a new type of treasure-rewarding minigame for Amphoreus.

How Amphoreus treasure chests work

Opening chests will give you Celestial Ambrosia, which you can give to the Tides of the Basin in the Vortex of Genesis. Giving up these collectables will level up the basin, allowing you to get rewards like Stellar Jade and the item to increase the Trailblazer’s Remembrance Eidolon. (This is pretty much the same thing as the Clock Credits and Clockie Statue situation from Penacony’s treasure chests.)

Amphoreus doesn’t have Warp Trotters, trash cans, or any of the previously seen collectables on other planets, but you do have to watch out for Spirithiefs, who will show up and yoink your chest before you grab it. Sometimes the Spirithief will challenge you to a battle, too, so make sure you’re ready to fight. That said, our map marks the Spirithiefs on the map with their respective icon, but most spirits give you both a reward for thwarting them and a chest, so they are counted twice in the treasure tracker in the corner of your map.

This new area has some unique maps, sprawling over many floors. It does have rooms with 3D maps, though there’s no wall-walking or anything like that. The rooms switch between dawn and evernight, subtly changing the map and making different enemies and chests appeared. For the sake of keeping things clean, we’ve displayed all the chests on one map, though you will have to swap between the two time settings to find them all.

‘Eternal Holy City’ Okhema chest locations

Okhema is huge, so we’ve broken up the maps, separating the right side (Marmoreal Palace) from the left side (Marmoreal Market).

‘Bloodbathed Battlefront’ Castrum Kremnos chest locations

‘Bloodbathed Battlefront’ Castrum Kremnos F1

The Spirithief in the hall before the 3D room does not appear as a chest. It’ll show up after you try to pick up a nymph that’s sitting on the wall in the marked location. Though you won’t get a treasure chest from thwarting this Spirithief, you will get the usual rewards, and it still counts towards the treasure tracker in the corner.

The 3D map room in the north (the round one) has a secret elevator that opens up and gives you four chests (one in the center of the room and three below it). To access it, you need to do the side quest “I Once Was in Arcadia.”

‘Abyss of Fate’ Janusopolis chest locations

‘Abyss of Fate’ Janusopolis F2

In the large northern 3D room, you’ll need to use the scales to go up to the third floor. Use the giant hand to pick up the sphere against the wall during dawn and place it on the right side of the scale. Stand on the left scale to be lifted up. After navigating this top floor, you can activate the lift to go around the different floors freely.

Vortex of Genesis chest locations

‘Sanctum of Prophecy’ Janusopolis chest locations

This area was added in version 3.1.

Notably, there are a ton of chests (that don’t get counted by the on-map chest counter) that appear as part of the “Janus’ Maze” quest, which unlocks via the northeast library area of F1. The quest will be marked on your map with a blue symbol.

‘Sanctum of Prophecy’ Janusopolis F1

This floor is where a bulk of the loot is, so make sure you’re thoroughly searching using our map. We recommend sweeping through the 3D rooms completely during dawn or evernight before swapping to the other setting to make the search easier.

‘Murmuring Woods’ Grove of Epiphany treasure chests

This area was also added in version 3.1.

‘Murmuring Woods’ Grove of Epiphany F2

Note that the Spirithief in the southern area doesn’t steal a chest, but rather steals one of those huge blocks you can rewind and use to clear paths. Using it after taking down the Spirithief will allow you to unlock the door on F1 as well as get the nearby chest.

‘Demigod Council’ Dawncloud treasure chests

This very long area was added in version 3.2.

Note that the northern Spirithief actually steals the floating scroll in the marked location, not a chest.

‘Dragonbone City’ Styxia treasure chests

This area was also added in version 3.2.

‘Dragonbone City’ Styxia F1

The 3D room is more complicated than it looks. After you initially make your way through towards the space anchor inside, make sure to use the controllable giant hand to break any boxes around the map. This will effectively let you explore the full area, using the spotlight mechanism to grab all the chests during day and night.

‘Dragonbone City’ Styxia F2

This 3D room is much more annoying than the previous one. You’ll need to use the hidden passage mechanisms to fully explore it all.
