Skull Cavern Map Predictor
Use this Skull Cavern map predictor to inspect potential dinosaur levels and related mine events from your Stardew Valley save state. The Mines tab shows a month calendar with regular mine events and Skull Cavern planning signals.
how to use it
How to read the Skull Cavern map predictor
The tool calculates seeded mine events by day and floor. It lists mushroom floors, monster infestations, slime infestations, quarry floors, and potential Skull Cavern dinosaur floors.
1
Upload the save
A save file gives the predictor version, days played, quarry status, hardmode mine status, and related state.
2
Open Mines
This page selects the Mines tab by default so you can browse the current month quickly.
3
Check the calendar
Each day lists regular mine signals and a separate Skull Cavern dinosaur-level line.
4
Move by month
Use Previous Month, Next Month, Previous Year, and Next Year to plan future Skull Cavern runs.
5
Treat dino floors as potential
The predictor identifies potential dinosaur floors, but live map selection can still prevent a floor from appearing.
example
Example Skull Cavern planning workflow
Before a deep Skull Cavern run, upload the save and scan the calendar for days with useful potential dinosaur levels. Pair the result with daily luck and your in-game resources before committing to a run.
Input: Save file or ?id=42069&dp=250&qu=1&hm=0
Output: Month calendar with mushroom, infestation, quarry, and potential dinosaur floor rows
Best for: Pepper Rex hunting, mine planning, mushroom floor checks, and Skull Cavern route decisions
accuracy
Skull Cavern prediction notes
Potential means possible, not guaranteed
The game performs map selection steps that are not fully represented by the predictable seed, so dinosaur floor results should be treated as planning signals.
Version changes matter
Stardew Valley 1.4, 1.5, and 1.6 changed several mine rules, so detected version affects the calculation.
Quarry and hardmode flags matter
Quarry access and mine difficulty can affect which floor types should be calculated.
Calendar view is intentional
Mine and Skull Cavern plans are date-based, so the tool presents the output as a browsable month rather than a single-row result.
run checklist
When to use the Skull Cavern map predictor
Use the Skull Cavern map predictor before a resource-heavy Skull Cavern day, especially when you are hunting Pepper Rex kills, dinosaur eggs, or a cleaner deep-run route. The Skull Cavern map predictor does not replace in-game luck, food, staircases, bombs, or rings, but it gives a date-based signal that can help you choose which day deserves those resources.
Before a dinosaur hunt
Scan the Skull Cavern map predictor calendar for potential dinosaur floors, then pair the signal with your luck day and available supplies.
Before a mine reset
Use the same Mines tab for mushroom floors and infestations so your Skull Cavern planning does not ignore regular mine opportunities.
Before seed-only sharing
Include Game ID, days played, quarry status, hardmode status, and version so the Skull Cavern map predictor starts from the right state.
Before trusting one row
Treat every dinosaur listing as potential. The map can still roll a different layout, so plan backups rather than spending all resources on one prediction.

Skull Cavern Map Predictor FAQ
What does the Skull Cavern map predictor show?
It shows potential Skull Cavern dinosaur floors and related mine calendar events such as mushroom floors, infestations, slime infestations, and quarry floors.
Are predicted dinosaur floors guaranteed?
No. The list is a useful planning signal, but the game can still make map choices that prevent a potential dinosaur floor from appearing.
Does daily luck change the Skull Cavern map predictor?
The displayed mine-floor logic is driven by seeded map and floor checks. Daily luck is still important for a run, but it is not the only planning factor.
Why does the tool need quarry status?
Quarry-related mine floor checks depend on whether the quarry is unlocked, so save-state flags improve the prediction.
Can I use this with only a Game ID?
Yes, but add days played and relevant flags such as qu for quarry unlocked and hm for hardmode mines when possible.
Does this replace BlaDe's Map Predictor?
No. This page focuses on RNG-based floor signals from the integrated Stardew Predictor. Dedicated map tools can cover different map and artifact-digging workflows.
