The interactive Palworld breeding explorer

Every pal has a hidden breeding power. The child of two parents is the breedable species whose power is closest to the parents’ average — floor((powerA + powerB + 1) / 2) — with ties going to the higher-priority species. Around 131 special combos override the math (for example Relaxaurus + Sparkit always hatches Relaxaurus Lux), and same-species pairs always breed true.

Fixed parent pairings that ignore the usual power-averaging and always produce a specific child — usually subspecies like Frostallion Noct (Frostallion + Helzephyr) or Relaxaurus Lux (Relaxaurus + Sparkit). Palforge derives all of them from the game’s full breeding table, including the gender-dependent Katress × Wixen pair.

A child always inherits 1–4 passives drawn randomly from the parents’ combined pool, at 40% / 30% / 20% / 10% for 1, 2, 3, or 4. Then 0–3 extra random passives are added (40% / 30% / 20% / 10%), capped at 4 total. That makes clean parents matter: junk passives dilute the pool.

If the parents together carry only the passives you want: 1 passive passes 100% of the time, 2 passives ≈60%, 3 passives ≈30%, and all 4 ≈10% per egg. Palforge’s Explorer computes these odds for any setup, including junk-diluted pools, and estimates how many eggs you’ll need.

Legendaries such as Jetragon, Frostallion, Paladius and Necromus never result from power-averaging — breeding two of the same legendary is the only pairing that produces them. Some legendary subspecies do have combos, like Frostallion + Helzephyr → Frostallion Noct.

Roughly 1% of eggs (about 3% with an Extravagant Vegetable Cake) hatch as a Mutated Egg: the same species the pairing would normally produce, but with boosted stats and one of the exclusive rainbow passive skills that regular breeding and wild spawns can never roll.
