The mechanics behind the egg.

Where this data comes from, and how much to trust it

Palworld left Early Access with a "1.0" update on July 10, 2026, adding 98 new or restructured pals and reworking large parts of the game. PalBreedPedia's breeding data was originally built and cross-verified against palworld.wiki.gg's Breeding page, covering the 140 pre-1.0 pals, an approach that held up well: those numbers matched a second, independently maintained source exactly.

Covering the full post-1.0 roster is a different situation. As of this writing, the two most-cited community wikis (Fandom and wiki.gg) had not finished updating their breeding tables for 1.0. Fandom's own editors flagged their content as stale. Digging into a single new pal (Knocklem Ignis) turned up three sources claiming one parent pair, one source saying no combo exists, and one source saying it can't be bred at all. These are direct contradictions, not just gaps.

Given that, PalBreedPedia's current dataset covering all 297 pal forms comes from a single source, palworld.gg (single source, 1.0 roster, unverified), pulled 2026-08-22. Here's exactly what that means in practice:

• Breeding power numbers for all 297 pals: single-sourced, not yet cross-checked against an independent second source.
• Eligibility for the 199 pre-1.0 pals: carried over directly from the verified old dataset (a safe assumption, since eligibility rules rarely change between patches).
• Eligibility for the 98 new pals: an educated guess based on naming patterns (a pal named "X Cryst" is assumed combo-locked if a plain "X" also exists), not confirmed against the game itself.
• Fixed combos and same-species-only list: still the old, pre-1.0 list. Nothing new was added here rather than guess, given the contradictions found above.
• Tie-break order for equidistant formula results: alphabetical, since the source doesn't expose the game's real tie-break index. The real game may resolve ties differently.

Practical takeaway: for the 140 pre-1.0 pals, trust this data the way you'd trust any well-sourced wiki. For the pals flagged NEW on the Pal database, treat the result as a reasonable starting point, not a guarantee, until it's independently confirmed. This section will be updated once a second source stabilizes.

The standard formula

Every pal carries a hidden number the community calls its breeding rank (also "CombiRank" or "breeding power"). It has nothing to do with level, stats, or the label on its status screen. It exists purely to decide what an egg turns into. Lower numbers sit at the top: rare, powerful pals. Higher numbers are the common pasture fodder you catch in the first hour.

Put a male and female pal of any two species into a Breeding Farm with a cake, and the game averages their ranks:

Whichever formula-eligible pal has a breeding rank closest to that number is what hatches. If two species are exactly equidistant, the game breaks the tie toward the lower index number. This is also why the result is never rarer than either parent: the average can't fall outside the range you started with.

Three ways the formula gets overridden

• Same species: two of the same pal always produce that pal, no averaging involved.
• Fixed combos: a specific list of exact pairings, usually elemental variants like a Cryst, Noct, Aqua, or Ignis form, that always produce a set result regardless of rank. Full list below.
• Same-species-only pals: a handful of pals (mostly late-game and legendary) can never be reached through the averaging formula at all. The only way in is breeding two of themselves, or via one of the fixed combos below.

Fixed combo reference

These override the formula completely. If your pair matches one of these, this is what you get, no averaging involved.

Mutations

Mutation is a separate roll layered on top of every egg, not a different formula. Base odds are 1% per egg; an Extravagant Vegetable Cake raises that to 3%. A mutated egg always hatches into something notably rarer than the pair's standard result, guaranteed Alpha, at Condensation Level 2, with four passive skills, at least two of them Tier 4, and one guaranteed to be a mutation-exclusive passive (Babysitter, Heavily Armored, Idiosyncratic, Immortality, or Skymarcher). See the mutation calculator for a cake-by-cake breakdown.

Passing down passives and active skills

Breeding also rolls for which passive skills and active skill carry over from the parents to the egg. Species is only half the picture. A Special Cake improves the odds a passive skill transfers. Passive and skill inheritance is randomized per-egg and isn't something a calculator can pin down in advance, so PalBreedPedia focuses on predicting species and leaves skill rolls to the game.

Working toward a target, step by step

1. 1

   Look up your target's breeding rank on the Pal database.

2. 2

   Already own a pal you'd like to build from? Use Breeding Path to search forward.

3. 3

   Starting from the target instead? Use Breeding Tree to explore parent pairings backward, generation by generation.

4. 4

   Check the fixed combo list above first if your target is a Cryst/Noct/Aqua/Ignis variant. It's usually faster than laddering through ranks.
