Honkai Star Rail 4.0 introduced Planarcadia, and scattered across its four main areas are Floating Grease Origin Retrace Shiftmation puzzles. Solving them is the only way to obtain Imagenate Fragments, which you need to unlock the Floating Grease Chronicles game mode in Duomension City. Each area has its own set of puzzles tied to a specific fragment type, and you won't be able to access the Chronicles worlds until you've cleared them all.
Quick answer: Find and complete the Floating Grease Origin Retrace Shiftmation puzzles in Duomension City, Graphia Academy, Dovebrook District, and "World's End" Tavern. Each set of puzzles rewards a unique Imagenate Fragment that unlocks the corresponding Floating Grease Chronicles world.
What Are Imagenate Fragments and Why You Need Them
Imagenate Fragments are special items tied directly to the Floating Grease Chronicles, a platformer-style game mode accessible from Duomension City. The mode contains four worlds, and each world requires a specific Imagenate Fragment before you can enter. You earn these fragments exclusively by completing the Floating Grease Origin Retrace Shiftmation puzzles found in the overworld — there is no alternative way to obtain them.
Once you use a fragment to unlock a world, you can play through it and earn Stellar Jades as completion rewards. Since these puzzles also grant Arcadian Tokens (the main exploration currency for Planarcadia), clearing them serves double duty for your overall progression.
All Imagenate Fragment Locations by Area
Each of Planarcadia's four zones contains Shiftmation puzzles that reward a distinct Imagenate Fragment. The table below maps every area to its fragment type.
| Planarcadia Area | Imagenate Fragment Reward |
|---|---|
| Duomension City | Dual-Phase Winds Imagenate Fragments |
| Graphia Academy | Absent Moon Imagenate Fragments |
| Dovebrook District | Mass Cacophony Imagenate Fragments |
| "World's End" Tavern | Gift of the Earth Imagenate Fragments |
You can tackle the areas in any order, but each zone's puzzles must be fully completed before the corresponding Chronicles world becomes available.
How the Shiftmation Puzzles Work
Floating Grease Origin Retrace Shiftmation puzzles are overworld challenges scattered across Planarcadia. They appear as interactable objects in the environment, and each one presents a spatial or logic puzzle you need to solve on the spot. The puzzles vary in complexity — some involve repositioning elements, while others require you to trace a specific path or sequence.
Each area contains multiple Shiftmation puzzles (not just one), so make sure you've found and solved every puzzle in a given zone before moving on. If you're missing a fragment, it almost certainly means an unsolved puzzle is still waiting somewhere in that area. Using the in-game interactive map or checking the exploration percentage for each zone can help you track down any you've missed.
Solving the Duomension City Puzzles
Duomension City is the first area most players explore, and its Shiftmation puzzles tend to be the most straightforward. Look for the puzzle markers near major landmarks and pathways. Completing all of them awards the Dual-Phase Winds Imagenate Fragments, which unlock the first Floating Grease Chronicles world.
Since Duomension City is also where the Chronicles mode itself is located, you can immediately test your fragment after earning it by heading to the Chronicles terminal.
Solving the Graphia Academy Puzzles
Graphia Academy's puzzles are slightly more involved. The area's layout includes elevated platforms and indoor sections, so some Shiftmation challenges may be tucked away in less obvious spots. Completing the full set here grants the Absent Moon Imagenate Fragments.
Solving the Dovebrook District Puzzles
Dovebrook District rewards Mass Cacophony Imagenate Fragments upon clearing its Shiftmation set. The puzzles here tend to be spread across a wider area, so thorough exploration is important. Check side paths and areas that seem like dead ends — Dovebrook hides several of its puzzles off the main routes.
Solving the "World's End" Tavern Puzzles
The final set of Shiftmation puzzles is in "World's End" Tavern, and completing them earns the Gift of the Earth Imagenate Fragments. This area's puzzles can be among the trickiest, so take your time reading the environmental cues before committing to a solution. Incorrect attempts can usually be reset without penalty.
Unlocking and Playing the Floating Grease Chronicles
After collecting all four types of Imagenate Fragments, head back to Duomension City and interact with the Floating Grease Chronicles terminal. Each fragment unlocks its corresponding world within the mode.
The Chronicles themselves play as a platformer — a departure from Honkai Star Rail's usual turn-based combat. You navigate through side-scrolling stages, and completing each world awards a generous amount of Stellar Jades. There are four worlds total, one for each fragment type, and all of them are worth clearing for the rewards alone.
How to Confirm You've Finished Everything
You'll know a Shiftmation puzzle is complete when the fragment reward appears in your inventory and the puzzle marker disappears from the overworld. For the Chronicles mode, each world shows a completion status after you clear it. If a Chronicles world still appears locked, revisit the corresponding Planarcadia area and check for any remaining unsolved puzzles — the exploration percentage tracker can point you in the right direction.
Between the Imagenate Fragments, the Stellar Jade rewards from the Chronicles worlds, and the Arcadian Tokens earned along the way, the Floating Grease Origin Retrace Shiftmation puzzles are some of the most rewarding overworld content in Honkai Star Rail 4.0. Clearing them early gives you a solid head start on Planarcadia's progression systems.
