Palworld Mutation Calculator 1.0: Mutated Egg Odds & Passives

Mutation landed in 1.0. Every bred egg can mutate into a stronger hatch with rainbow passives. People digging through the files put the base at ~1% per egg, or ~3% with Deluxe Vegetable Cake. Last checked 2026-07-13.

Food at the Breeding Farm

Any regular food / cake Base mutation rate. 1 egg per cycle. Deluxe Vegetable Cake +2 percentage points to mutation chance Vegetable Cake No rate boost. 2 eggs per cycle.

Breeding cycles 50 cycles

One cycle is one egg production tick after the farm has food. Vegetable Cake makes two eggs per cycle.

How mutation works in 1.0

Each egg rolls on its own. Bad luck streaks do not make the next egg luckier. The math is 1 - (1 - p)ⁿ. Mutated eggs look different in the farm, so you know before you hatch them.

One roll per egg

Food sets the per-egg chance. Cycle count (and Vegetable Cake's extra egg) sets how many rolls you get.
What players keep seeing

Reports line up on Alpha status, two condensation stars, very high IVs (often 90+), and rainbow passives. Those can stack with passives inherited from the parents.
Species is still messy

Most mutated eggs hatch a different, stronger species. Not always. Some pairs keep spitting out the same result (Hartalis pairs often make Aegidron). Others have produced same-species Alphas or mixed outcomes. Nobody has pinned the species rule in the files yet. Use the breeding calculator for the normal child, then treat mutation as a separate roll.

Rainbow passives on mutated Pals

Four passives sit under MutationPal_* in the files. Call them mutation-linked, not exclusive. Immortality has also shown up from relic washing chips. Full named list (all ranks, Surgery tags) is on the passive skills page.

Linked to mutation

These are the ones most tied to mutated hatches.

Passive	Effect
Immortality	Attack +15%, Pal auto health regeneration rate +100%, Life Steal +5%
Idiosyncratic	Pal & player auto health regeneration rate +50%, Defense +25%, immune to Poison and Burn damage
Babysitter	Egg production speed +30% and incubation speed +30% for Pals assigned to a Breeding Farm
Heavily Armored	Immune to explosion damage

Other rainbow passives that can appear

You can get these elsewhere too (rare fishing is one example). They still show up on mutated Pals.

Passive	Effect
Skymarcher	Mounted jump count +2
Lightfooted	Mounted jump count +1
Ranch Master	Farming work suitability +2
Lavish Hospitality	Dropped items +100% (only the Pal carrying it; pays out on capture and butcher)

What helps the mutation chance

Deluxe Vegetable Cake: +2 percentage points (1% to 3% per egg). This is the real boost.
Vegetable Cake: same rate as regular food, but two eggs per cycle. More rolls for cheaper ingredients.
Mushroom Cake: no mutation effect. Adds 1-5 IV talent points instead.
Myths: no good evidence that monitoring stations, Ancient Hatchery, or breeding two mutated parents changes the rate.

Host a Palworld server for breeding

Farms and incubators keep working while you are offline, which helps when you are rolling a lot of eggs for a mutation. Leave RAM headroom if you automate heavily.

FAQ

What is a mutated egg in Palworld 1.0?

Every Breeding Farm egg can mutate on its own roll. Mutated eggs look different in the farm and unlock an achievement when you hatch them. The hatch is usually Alpha, two condensation stars, very high IVs, and rainbow passives on top of whatever the parents passed down.

What is the Palworld mutation chance?

People digging through the 1.0 files put the base at about 1% per egg. Deluxe Vegetable Cake adds 2 percentage points, so about 3% per egg. Pocketpair has not posted official numbers.

Does Vegetable Cake raise mutation chance?

No. It does not change the per-egg rate. It does make two eggs each cycle, so you get twice as many rolls for cheaper food. Deluxe Vegetable Cake is the one that raises the rate.

Do mutation odds build up over time?

No. Each egg is its own roll. The calculator stacks them with 1 - (1 - p)^n for the chance of at least one mutated egg after n eggs.

Does breeding two mutated parents raise the rate?

Nothing solid points that way. Same for monitoring stations or Ancient Hatchery. Use Deluxe Vegetable Cake for a higher rate, or Vegetable Cake if you want more eggs per cycle.

Which rainbow passives come from mutation?

Immortality, Idiosyncratic, Babysitter, and Heavily Armored show up under MutationPal_* in the files. Mutated Pals can also roll Skymarcher, Lightfooted, Ranch Master, and Lavish Hospitality, which also drop from other sources.
