Selected room
Selected room
Start / Frostbed
Recognize it by
Frozen material above a Water basin
Goal
Create a frozen crossing.
Need
Frozen path
Recovery
This room has no dedicated reset. Stop before consuming more of the room material.
Hint
Look at the frozen material above the Water basin, not at the Artifact itself.
Strong hint
The crossing is made when frozen material falls into the Water. Work that overhead material from outside the locked zone.
Full solution
- Work from outside the locked inner zone.
- Release enough frozen material into the Water basin to form a crossing.
- Cross the frozen path and collect the Artifact.
Selected room
Temple 2
Recognize it by
Crackstone blocking the Artifact
Goal
Break the Crackstone barrier.
Need
Rocket / explosive
Recovery
No reset is needed. Come back after you have Rocket / explosive excavation.
Hint
This room is blocked by a material you cannot route around.
Strong hint
You need an excavation tool, not a routing setup. Come back when Rocket or explosive excavation is available.
Full solution
- Return once the Rocket Launcher or explosive excavation is available.
- Break the Crackstone barrier.
- Walk through and collect the Artifact.
Selected room
Burn
Recognize it by
Long burnable fuse and frozen material
Goal
Ignite the fuse to drop the ice.
Need
Flamethrower
Recovery
There is no dedicated reset. Open the room-specific recovery steps before changing more of the room.
Hint
Follow the long fuse with your eyes before you start changing the room.
Strong hint
The fuse has to burn through to the support under the frozen material. Lighting it is the start, not the whole job.
Full solution
- Use the Flamethrower from the permitted ignition side.
- Let the fuse burn to the support under the frozen material.
- Allow the released material to fall into Water and form a crossing.
- Cross and collect the Artifact.
Selected room
Timer
Recognize it by
Timed fuse / staged frozen paths
Goal

Recovery
Use the room reset control if the sequence needs to be restarted.
Selected room
Rocket Burn
Recognize it by
Water basin with frozen material
Goal

Need

Recovery
This room has no dedicated reset. Stop before consuming more puzzle material.

Build
Recognize it by
Yellow build squares and a Lava routing puzzle
Goal
Route Lava to create the path.
Need
Foundation · Lava
Recovery
There is no dedicated reset. Rebuild the route with Foundations; saves previously soft-locked by a Thermal Buffer should self-heal on load.
Hint
Focus on the support beneath the frozen material, not on the Artifact itself.

Bridge
Recognize it by
Bedrock maze
Goal
Reach the center through the maze.
Need
No special tool
Recovery
No reset is needed. This room is navigation only.
Hint
Treat this as a pathfinding room, not a construction puzzle.
Strong hint
There is no hidden sensor or Lava trick here. The Artifact is in the central chamber through the Bedrock corridors.
Full solution
- Enter through the maze opening.
- Navigate the Bedrock corridors into the central chamber.
- Collect the Artifact. The exit teleport returns you near the entrance.
Selected room
Pach
Recognize it by
Water routing + two sensor areas
Goal
Reach the Artifact after the Water condition is complete.
Need
Foundation · Water
Recovery
There is no dedicated reset. Keep the Water in the room and rebuild the route with Foundations.
Hint
Watch what changes when one sensor is full. Does the room behave as if that progress is being remembered?

Moonpach
Recognize it by
Mooncrystal over many sensor pads
Goal
Fill all 12 sensors.
Need
Gun · Moonhop
Recovery
There is no dedicated reset. Preserve the Mooncrystal / Moonhop supply.
Hint
Don't focus on firing faster. Watch where the Moonhop settles and which sensor areas remain incomplete.

Choose the problem you are seeing.
The Artifact door won't open
Likely cause
The puzzle condition is not fully active yet, or a required sensor/material has moved.
Check

General questions
How many Artifact puzzles are there?+−
There are 9 Artifact puzzles. Use the room images if you do not know the name.
How do I identify which Artifact room I am in?+−
Match the room thumbnail to what you see in-game, or search a mechanic such as Lava, sensors, Mooncrystal or maze.
Can Artifact puzzles be reset?+−
Recovery depends on the room. Some puzzles provide a direct reset or recovery path, while others are better handled with room-specific instructions. Use the solver for the room you are in before changing more of the puzzle state.
Spoiler questions
SpoilerWhy won't an Artifact door open?+−
The full puzzle condition still has to be active. For Pach and Moonpach, every required sensor must stay filled at the same time.
