Penacony is the third area you’ll visit in Honkai: Star Rail, and with it comes new treasure and puzzles to complete on the planet. With over 100 new things to find, it can be a lot to scour out all at once.
A lot of the places in Penacony will only unlock once you’ve completed a certain part of the main Trailblaze Missions or have completed certain puzzles. Because of that, we recommend hunting all the treasure once you finish the story.
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) and Warp Trotters.
Update (Dec. 18): We’ve added the chest locations for the new map (Dream of Gnawing Oak) added in version 3.8.
How Penacony treasure chests work
Opening chests and solving puzzles around Penacony will reward you with Clock Credits, which you can turn in to level up the Clockie statue in the center of Golden Hour. Leveling up the statue nets you rewards like Stellar Jade and other goodies.
There are lots of new puzzle types to Penacony, including block-sliding mirror puzzles and literal puzzles (with pieces you have to fit in to make an image). Most notably, there’s a new type of collectable found under the treasure chest drop down when you look at maps: “Lordly Trashcans.” These garbage pails will ask you a question, and if you answer correctly, they’ll give you a reward. If you answer wrong, they’ll engage you in battle — and you’ll still get the same reward after, so don’t worry about answering wrong.
Penacony also has quite a few maps where you’ll be walking on walls; the map there is 3D. While it’s obviously tough for us to convey information on where to find each chest, Warp Trotter, or Lordly Trashcan in these spaces, we did our best to show where the chests are located using circles to indicate which platform the object is on.

The Reverie (Dreamscape) treasure chest locations

Dewlight Pavilion treasure chest locations
Dewlight Pavillion (F1)
Dewlight Pavilion (F2)
To access the 3D room in the northeast, you’ll need to talk to Burton, an NPC right outside the door. After running through the 3D room several times and finding chests (which don’t contribute towards the chest counter in the corner of the map), you’ll eventually get to a Hanu puzzle. The two chests that do contribute towards the counter are part of the Hanu puzzle.
Dewlight Pavilion (City Sandpit)
Clock Studios Theme Park treasure chest locations
Clock Studios Theme Park F1
To reach that northern area, you’ll need to enter a Hanu door, accessed from the northern area of the second floor.
Clock Studios Theme Park F2
One of the treasure chests in the southern Hanu puzzle area can be tricky. The hidden chest is behind the sign next to the Hanu TV set, and you’ll have to use Hanu’s small stature to get behind it.
Another hidden chest is beyond the Bubble Pinball Machine in the south. Set it up like this to shoot off to a hidden platform:
Dreamflux Reef treasure chest locations
Dreamflux Reef (F1)
Interact with the purple bubbles in the south to get the first Lord Trashcan in the area.
Dreamflux Reef (F2)
To get to the eastern rooftop area, insert an Aideen token into the lampost in the connecting plaza area.
SoulGlad Scorchsand Audition Venue treasure chest locations
Whichever paths you didn’t take during the main scenario portion of this area will become available once you do the adventure mission “Scorchsand Vacation.”
Note that each of these areas have secret paths to unlock further things in each zone. To unlock these paths, you’ll need to talk to the soda-headed NPCs in each zone, and then enter the Audition Shuttle. When you select a path to take, the bottom right corner will tell you what you need to do in order to create the secret path. If you’re struggling, just keep hitting the buttons that the hint labels with a question mark until all three checkmarks appear in the corner.
We honestly recommend running through this area for the story, then do the aforementioned side quest, while stopping to talk to every Mr. Soda NPC you see. Talk to all six in each zone, then activate the secrets at the Audition Shuttles. Then finally you can fully explore each zone to the fullest.
Given how complex this map is, we’ve broken up each area by what number they’re ordered by in-game.
SoulGlad Scorchsand Audition Venue area 1
The Lordly Trashcans and Warp Trotter will only appear if you’ve taken the aforementioned hidden route to these areas.
SoulGlad Scorchsand Audition Venue area 2
The bottommost floor of the Gunfire Trial and the smaller, puzzle-filled isles on the east side of the Time Trial are locked behind the hidden routes to these areas.
SoulGlad Scorchsand Audition Venue area 3
The chests on these maps will appear no matter what path you take here, but there will be a little surprise for you in the center areas of both of the arenas if you take the hidden routes.
Penacony Grand Theater treasure chest locations
The 3D Dreamscape rooms in this area are huge, but luckily, you should be able to run into all the chests quite quickly if you just follow the path forward in each area. There’s path in each 3D room is pretty linear, so there isn’t too many places to get lost in, luckily.
The southeastern 3D room has a side quest involved with it. Talk to the NPC right outside of the portal to start the quest “Loothunt in Mazeville.” All the chests inside only correlate to the quest — there are no chests that count toward the treasure counter that show up on the map, which is why it’s left off of our map.
The bunches of chests on the eastern side by the bar are also tied to the nearby Hanu puzzle. Completing the challenge will make three chests appear.
The Radiant Feldspar treasure chest locations
The ship added in version 2.3 goes by “The Radiant Feldspar” at first, but after completing the side quest “Cloud-Bound Hearts,” the boat will be renamed based on your choice: “The Trailblaze’s Stern,” “The Talalov,” or “The Soaring Clock Hand.” For the sake of continuity, we’re using its original name in this guide.
The Radiant Feldspar B1
The Radiant Feldspar F1
The Radiant Feldspar F2
Penacony Paperfold University College treasure chest locations
This area was added in version 2.6, as part of the “Banana Outrage: Battles Without Ninja and Humanity” side story.
Dream of Gnawing Oak treasure chest locations
This area was added in version 3.8. The area is pretty small, but we recommend finishing the Trailblaze Mission associated with this area first, so you can freely explore it without any story boundaries holding you back.
Dream of Gnawing Oak F1
Dream of Gnawing Oak F2
Dream of Gnawing Oak F3
