How does breeding work in Palworld?

Every Pal has a hidden Combi Rank (Breeding Power). For most parent pairs, the child is the Pal whose Combi Rank is closest to floor((rankA + rankB + 1) / 2). A set of special parent combinations override that formula to produce unique Pals, and a handful of legendaries can only be bred from two of themselves. The species of the egg is fixed by the pairing — only passive skills and stats vary.

How do I breed legendary Pals like Jetragon or Frostallion?

Legendaries such as Jetragon, Frostallion, Necromus and Paladius are self-only: the only way to hatch one by breeding is to pair two of the same legendary. Most players catch the first one in the wild, then breed two together to roll better passive skills.

How Palworld breeding works

Every Pal has a hidden Combi Rank (also called Breeding Power) — a number from 1 for the rarest Pals up to 1500 for the most common. When you put a male and a female in a Breeding Farm with Cake, the game decides the egg's species with three rules, in this order:

Same species. Two of the same Pal always breed that same Pal — the reliable way to farm better passive skills.
Special combo. Around sixty hand-picked parent pairs override the maths to make a unique Pal (this is the only way to get the Lux / Cryst / Noct / Terra / Aqua variants and Pals like Anubis-line uniques).
The formula. For everything else: childRank = floor((rankA + rankB + 1) / 2), and the egg is the Pal whose Combi Rank sits closest to that value. Ties go to the lower internal index.

Parent order and sex don't change the species — only which passives and stats carry over. A small group of legendaries (Jetragon, Frostallion, Necromus, Paladius and a few others) are self-only: you can't average your way into them, so the lone breeding route is two of the same legendary.

Frequently asked

Does it matter which parent is male or female?

No. You need one of each sex to breed, but the species of the egg is identical regardless of which parent is which. Parent order doesn't matter either — this calculator treats A + B and B + A as the same.

How do I breed legendaries like Jetragon or Frostallion?

They're self-only. The only breeding route is to pair two of the same legendary, so most players catch the first one in the wild, then breed two together to roll better passive skills onto the offspring.

Why are there so many parent pairs for one Pal?

Any two Pals whose Combi Ranks average into a target's range will breed it, so a common Pal can have hundreds of valid pairs. We list them all, easiest-to-obtain parents first, and you can filter to pairs that include a Pal you already own.

Are the combinations up to date?

The Pal ranks come from the actively maintained palcalc dataset (currently patch data v22) plus the datamined special-combo list. The Terraria collab combinations aren't in this version yet; every other Pal and combo reflects the current game.

What do I actually need to breed?

A Breeding Farm, a male and a female Pal placed inside, and Cake in the farm's storage. The egg's species is what this calculator predicts — incubate it to hatch the Pal.

Pal data & icons: palcalc v22 + paldb.cc (special combos & Pal icons). The Terraria collab combo matrix is omitted for now — those Pals still resolve through the formula, which may not match their in-game unique combo. Full list at paldb.cc. Spot something off? Report it.
