Palworld Breeding Guide (1.0)

What actually changed in 1.0, how the game decides which Pal hatches, and which passives you can — and cannot — breed onto a Pal. Every number here comes from the same 1.0 dataset behind our breeding calculator (44,851 combinations across 299 Pals).

How the game picks the child

Every Pal has a hidden Breed Power. When two Pals breed, the game averages the two parents’ Breed Power and hatches the Pal whose own Breed Power sits closest to that average — which is why two completely unrelated parents can produce something that looks nothing like either of them. A set of special pairs is hard-coded on top: those pairs always produce a fixed child regardless of the average, and that is how every variant (Noct, Cryst, Lux, Terra, Ignis…) is made.

Parent order never matters — Pal A + Pal B and Pal B + Pal A give the same result. Rather than memorise Breed Power values, put the two parents into the calculator, or pick the Pal you want and read its full combo list.

What 1.0 changed: the combination table was rewritten and 72 new Pals were added, so a recipe you memorised before 1.0 can now hatch a different Pal. That is the single most common reason a breeding calculator gives you the “wrong” child right now — it is still serving the pre-1.0 table. Every combo on this site is derived from 1.0 game data.

How passives are inherited

A chick can pick up passives from its parents, and it can also roll extra passives at random. The part that trips people up is that not every passive is in the random pool:

Passives that roll randomly — e.g. Ferocious, Artisan, Runner, Burly Body. Any breeding pair can produce them, so you can farm for them on any Pal. Each has a roll weight: weight 100 passives (Ferocious, Artisan) show up roughly 20× more often than weight 5 ones (Demon God, Swift, Remarkable Craftsmanship).
Passives that never roll randomly — Legend and every element “Emperor” passive (Ice Emperor, Divine Dragon, Flame Emperor…). These only exist on Pals born with them, so the only way onto another Pal is to breed through a parent that carries one. That is what the passive pages are for: each lists every Pal born with that passive.

Each Pal page shows this per-Pal: open any Pal and the Best passives section marks each passive as Born with it, Common roll, Rare roll, Route it in (with the parents that can carry it), or Impossible in 1.0.

Inheritance probabilities are community estimates — Pocketpair has never published them, so we do not print fake percentages. Which passives exist, their ranks, their roll weights and whether they can roll at all are verified 1.0 data.

The 26 Pals that can only breed with themselves

In 1.0 these 26 Pals have exactly one recipe — themselves + themselves. Every tower boss and every legendary is on this list. Two consequences worth knowing before you waste eggs:

You cannot breed toward them. No combination of other Pals will ever hatch one — you have to catch it.
You cannot route a passive into them. Since both parents must be the same Pal, an inherit-only passive it is not born with — Legend being the big one — can never be bred on. A Legend Orserk is not possible in 1.0. They can still gain passives that roll randomly.

They are still perfectly good parents for other Pals — Frostallion, Jetragon, Paladius, Necromus and Neptilius are born with Legend, and breeding one of them into a normal Pal is exactly how you get Legend onto that Pal.

Using the Breeding Farm

Build a Breeding Farm, drop in one male and one female Pal, and keep Cake in the chest — the pair consumes a Cake per egg and stops when there is none. The egg that appears is decided by the pair, not by the farm, so the farm is only ever a throughput problem: more farms and a steady Cake supply mean more attempts per hour. Since passive rolls are random, volume is exactly what you need when you are fishing for a specific passive.

Gender matters — you need one of each, and each Pal has its own male/female ratio (shown on every Pal page). A 90/10 species can take a while to pair up.

FAQ

Why does my old breeding calculator give the wrong Pal?: Because 1.0 rewrote the combination table. Anything still serving the pre-1.0 table will hand you a child that no longer hatches. Every combo here is derived from 1.0 data.
Can I breed a Legend Orserk?: No. Orserk can only be bred from Orserk + Orserk, and Legend never rolls randomly — so there is no parent that can bring it in. The same applies to every self-breed-only Pal above.
How do I get Legend onto a normal Pal?: Breed through a Pal that is born with Legend — Frostallion, Frostallion Noct, Jetragon, Paladius, Necromus or Neptilius. Open the target Pal’s page and the Best passives section lists the exact parents that can carry it in.
Does parent order change the child?: No. A + B and B + A always produce the same Pal.
Which passive should I actually farm for?: The weight-100 ones — Ferocious, Artisan, Runner, Burly Body. They roll about 20× more often than the weight-5 passives like Swift or Demon God, so they are far cheaper in eggs for a similar effect.
