How passive skill inheritance works in Palworld breeding
In Palworld, a child Pal inherits passive skills from the pool of both parents' passives. The game rolls how many passives the child gets, then fills those slots from the combined parent pool before adding random passives.

The inheritance roll
The game first rolls the number of inherited passives from the parent pool: roughly 40% for 1, 30% for 2, 20% for 3 and 10% for 4. Slots not filled from the parent pool are then filled with random passives, so a child can exceed the number of passives either parent had.
Why the pool matters more than the parents
Both parents' passives merge into one pool before the roll, so duplicate passives across parents do not double the odds — they shrink the pool, which raises the chance the passive you want is drawn. Two parents that both carry Legend are the fastest way to lock Legend into every offspring.
The 4-slot cap
A Pal can hold at most four passives. Once all four slots are filled with the passives you want, further breeding of that line can only dilute them, so retire the pair and move to stat work instead.
Reroll loop
Keep one 'donor' parent with the target passives and swap the second parent. Every cake cycle is a fresh roll from the merged pool — cheaper than re-catching wild Pals with the same passives.
