Choose both parents to check their ordinary child.

The standard target checks your parents’ species result. It does not affect mutation odds.

Select up to four on each parent. Shared traits count once in the combined pool. Use Ctrl / ⌘ to select several on desktop.

Mutation percentages use verified Linux defaults and exact finite-grid counts, interpreted with a uniform-input assumption. Repeated-egg and batch estimates additionally assume independent attempts. Actual PRNG uniformity and Windows parity are unverified. Passive estimates apply to ordinary eggs and exclude random extra traits.

Mutation-only traits

The current source table marks these 5 traits for mutated Pals. The pinned settings record a talent floor of 90/100 and internal starting rank 3; that rank is a data value, not three displayed stars. Their application to extra eggs from Grintale remains unverified for the fixed v1.0.3 baseline. The official v1.0.4 notes report a related extra-egg stat fix.

Immortality

Immortality restores its Pal carrier from actual HP damage attributed to that Pal. In the traced normal HP-damage path, shield-only damage restores nothing. Positive damage uses nominal 5% recovery, float32 multiplication/subtraction, truncation toward zero and a minimum request of 1 HP; recovery stops at the carrier’s effective maximum HP and does not revive it. It does not grant the trainer this self-targeted healing. Other damage callbacks and encounter healing-per-second are not established by this rule. Automatic regeneration raw 100 and Attack raw 15 are separate native slots.

Read the probabilities correctly

Special Cake’s zero mutation bonus retains the base threshold. Its default mutation input count matches Standard Cake; zero bonus does not mean zero total chance. The original reference data and conflicting historical claim remain in the source research.

The model chooses one, two, three, or four inherited slots with weights 40%, 30%, 20%, and 10%. It draws without replacement from the unique parent pool. If the pool is smaller than the slot count, all available traits are inherited. Special Cake uses four slots.

“All desired” allows other inherited traits. “Exact inherited set” excludes unwanted inherited traits. Neither predicts extra random traits or the separate trait generation of mutated eggs. Expected attempts are averages, and P90 is the number needed for a 90% chance under independent egg rolls.
