Breeding Calculator
Look up Monster Lab Simulator recipes by combining three essences. The table below is community-logged synthesis data — outcomes stay tagged unverified until confirmed on your live Early Access build.
Monster Lab Simulator recipes — what this tool is (and is not)
Most searches for monster lab simulator recipes want a clean list of essence trios → Fulu outputs. This calculator is that interactive list: pick three essences (or filter by rarity/element) and scan known community rows. It is not a code redeemer, trainer dump, or guarantee that every row still matches the newest Steam build.
Official store copy and this wiki’s verified teaching set use four essences: Fire, Water, Nature, Neutral. Third-party calculators that add Shadow or Light as live shop types are not confirmed against the Steam page as of 2026-08-18. Treat those extra slots as unverified until they appear in a numbered patch or in your client shop.
Early Access patches change economy and progression loops. Official Steam news through 2026-04-13 includes the Empower Your Fulus update (powders, extraction, empowering machines), extraction yield changes, and mission fixes in v0.2.3.3. Recipe rows that worked in February may still hatch — or they may need a re-test after you update. Always log the version string from your client.
For the process behind the list (fund tests with orders, extract failures, merge duplicates), use the recipe discovery workflow guide. For the full Fulu roster without a calculator, open the monster database.
Slot Essences
Choose three essences to match known synthesis recipes or test new combinations.
Filter Outputs
Filter results by rarity, element, habitat, and growth stage to target a lab goal.
Log Results
Save verified outcomes and tag them to the monster database for future runs.
Essence Primer
The calculator mirrors the Monster Lab Simulator synthesis loop: mix three essences, hatch eggs, and record the outcome. Track every result so your lab keeps improving.
Element names above match labels used in this wiki's community recipe rows. If a live build renames an essence, re-log the in-game string rather than forcing the old label.
Data Coverage
Why recipes break after patches
Official Steam posts since Early Access launch affect how you should treat any recipe list — including this one. Summaries only; open Steam news for full developer text.
| Date | Build / note | What changed for breeders |
|---|---|---|
| 2026-04-14 | Devlog #3: Fulu customization and new Fulus | No guaranteed live features until they ship in a numbered build — treat as roadmap context only. |
| 2026-04-13 | v0.2.3.3 v0.2.3.3 Patch Notes | Mission tracking and tutorial softlocks more reliable; re-check stuck Weekly/Daily objectives after updating. |
| 2026-04-01 | v0.2.3.2 Hotfix v0.2.3.2 | Fewer softlocks; seasonal special eggs easier to bank. |
| 2026-04-01 | The Egg Hunt Has Begun! | Timed exploration content — confirm whether the event is still active in your build. |
