Mutation and Cake Lab
Compare every 1.0 breeding cake, mutation attempts, parent-passive inheritance, and two-egg batch throughput using constants verified directly from the client data.

Step 1: Choose the standard child target
Pick the ordinary breeding result you are planning around. It does not change the odds and is not a mutation-species prediction; it only checks the standard result for your parents and links the full breeding guide.
Step 2: Who are the parents?
Choose the two pals you will breed. Their fixed species passives seed the pool in step 3, and the breeding solver checks their standard child.
Pick both parents to see the pal they produce.
Step 3: Build the passive pool
The picker contains all 115 player-facing traits in the current passive table. Parent fixed passives are already in the pool; add every other trait your actual parents carry so the inherited-set estimate matches your setup.
Step 4: Choose the passives you want
Mark the passives you actually want on the child. The odds panel shows how likely they all land and how many eggs that takes.
Add passives in step 3 (or pick parents that carry them) to start.
Step 5: Cake bonus

Mutation-only traits (5)
Build 24088745 sets the mutation talent minimum to 90 and the initial internal rank to 3. Its exact native species-selection routine is not present in the tables, so this page does not predict a mutation egg's species or assume it matches the standard child.

Cake comparison
Choose passives to compare inherited sets; mutation rates are already live.
| Cake | Mutation / egg | Mean mutation batches | Inherited set / egg | Mean passive batches |
|---|---|---|---|---|
| Standard Cake | 1.00% | 100 | — | — |
| Mushroom Cake | 1.00% | 100 | — | — |
| Vegetable Cake | 1.00% | 50 | — | — |
| Extravagant Vegetable Cake | 3.00% | 33 | — | — |
| Special Cake | 1.00% | 100 | — | — |
Parent-passive odds use the native 40% / 30% / 20% / 10% inheritance roll for one through four slots. Special Cake overrides that roll to four. Random extra passives are excluded, so inherited-set odds are lower bounds. Mutation odds stay separate because the recovered data does not establish an independent combined event.
Frequently asked questions
How do mutations work when breeding in Palworld?
Every produced egg has a 1% base mutation chance. Extravagant Vegetable Cake adds 2 percentage points, raising that egg to 3%. The 1.0 client sets the mutation talent minimum to 90 and its initial internal rank to 3. The exact native species-selection routine is not exposed in the tables, so this tool does not predict which species a mutation egg will hatch.
What do breeding cakes do?
Mushroom Cake adds 1–5 talent points to the offspring roll. Vegetable Cake produces two eggs per batch. Extravagant Vegetable Cake adds the same 1–5 talent bonus and raises mutation chance from 1% to 3%. Special Cake forces the child’s parent-passive inheritance count to four, or all available passives when the pool is smaller.
How are passive skills passed to a bred pal?
The normal inheritance roll chooses one, two, three, or four parent passives with 40%, 30%, 20%, and 10% probability. It then chooses that many from the unique combined parent pool. Special Cake overrides the count to four. Duplicate passives on both parents do not create extra entries in the pool.
Which passive skills are mutation traits in Palworld 1.0?
The current passive table marks five traits with AddMutationPal: Babysitter, Heavily Armored, Idiosyncratic, Immortality, and Skymarcher. The simulator exposes all five in its complete parent-passive picker.
