Palworld Breeding Calculator & Skill Inheritance Route Finder

A breeding calculator for Palworld. Predict the child from two parents, look up which parents produce the Pal you want, and search for the shortest route to inherit specific Active Skills.

Thanks for stopping by!

This site is made by a Japanese author, and translating every page properly takes more checking time than I can manage right now. So I started with the part I thought would be most useful to you: this breeding tool, fully in English. The rest of the site is still Japanese only - but the Pal data behind it is exactly the same, so the tool is always up to date. Happy breeding!

Update (2026/08/04)

Mutation support added.

The base mutation rate is 1%, rising to about 3% with the Luxurious Vegetable Cake. Vegetable Cake stays at 1% but lays two eggs at a time, so it works out to roughly 2% per breeding cycle. Chasing mutations is usually slower than just breeding normally, but mutated Pals start at rank 2 stars, so it is worth checking whether the condensed Pal you want happens to be reachable while you breed as usual.

Breeding internals and routes follow the official release build (v1.0.0) and have been verified in game.

How to use

1. Breeding Combos

• Parent x Parent = Child: pick two parents to see what hatches.

• Child only: shows every parent pair that produces that Pal.

• One parent + child: finds the partner candidates when one parent is fixed.

2. Inheritance Route

A route is a sequence of several breedings

Each result is a step-by-step plan. The first breeding alone will not produce your target. Use the child from each step as a parent in the next one, all the way to the last step.

• Target Pal: the Pal you ultimately want to create.

• Starting Pal: a Pal you already own, or the source of the skill. Leave blank to let the search pick the best starting point.

• Skills to Inherit: choose up to 6 Active Skills.

  • Picking 2 or more assumes you use a Special Cake, which passes on every skill in both parents’ slots (3 slots x 2 parents = up to 6, Unique Skills excluded).

  • Because skills are decided purely by the final two parents’ slots, results are shown as two branches: what to put on Parent A and what to put on Parent B. Skills your target learns by levelling up are excluded automatically, since they need no inheritance.

• Passive to Inherit: only passives that Pals are born with can be selected. Randomly granted passives cannot.

  • One skill and one passive can be searched together. The search starts from a Pal that knows the skill and looks for a route that uses a Pal with the passive as a parent somewhere along the way. If no such route exists, it falls back to a “two-line merge”: prepare one target Pal for the skill and another for the passive, then breed them together.

  • Two or more skills (Special Cake) cannot be combined with a passive.

3. Mutation

Every so often a breeding pair produces a Pal that is not the normal result. This is a mutation. A mutation always produces a higher-tier Pal than its parents, so weaker Pals can never be obtained this way.

Mutated Pals come with real advantages: their IVs are guaranteed to be 90 or above, and they can carry passive skills that only mutations get (Babysitter, Mutant, Immortal, Explosion Resistance and Air Walker).

The tab has two modes.

• From parents: pick two parents to see every Pal that pair can mutate into, with the share of each. The normal (non-mutation) child is shown alongside.

• From child: pick the Pal you want and see which parent pairs can produce it, sorted by chance. There can be thousands of pairs, so only the best 20 are listed.

Reading the percentages

The percentage in the list is the chance that a single egg turns out to be the Pal you want. It already combines the mutation chance itself with the chance of hitting that specific Pal, so it reflects what you will actually experience.

Tap a row to expand what that pair produces when a mutation does happen. Those figures are conditional on a mutation occurring, so they mean something different from the percentage above.

Cake

Only the Luxurious Vegetable Cake raises the mutation rate. Mushroom Cake and Special Cake affect talent and skill inheritance, but not mutations.

Vegetable Cake has the same mutation rate, but it lays two eggs at a time, which doubles your attempts. The list marks this as “(x2)”.

Narrowing down parents

• Allow as parents: toggles whether Legendary, Raid, World Tree-only, Meteor and Collab Pals may be used as parents. Uncheck a category to keep only combinations that avoid it.

• Only pals I own: searches using just the Pals you have registered. This list is shared with the Inheritance Route tab, so registering in either place updates both.

• Fix one parent: if one parent is already decided, this finds partners for it.

Notes

• Pairs where both parents are Dark type are marked “Insomniac”. They can be assigned at night as well, so they stay productive for longer. Individual Pals with the Insomniac passive behave the same way, but passives vary per individual and are not part of the calculation.

• Legendary, Tower Boss, Raid, Meteor and Collab Pals are never produced by mutation.

• Each row also shows the normal child for that pair. Those Pals accumulate while you wait for a mutation, which can help you decide which combination to run.

4. Saved Routes

Press the ”☆ Save” button on any result to keep that breeding plan. Because breeding can take days, the steps are frozen exactly as they were when you saved them - they will not change later.

• Saved plans appear in the “Saved Routes” tab. Click a card to expand the steps.

• Use “Delete” to remove one, or “Delete all” to clear them.

• Routes are stored in your browser and never sent to a server, so they do not carry over to another device or browser. Clearing your browser data will also clear them.

Switching language

Every Pal, skill and item name here is the official English name from the game. Use the 日本語 / EN buttons at the top of the tool to switch - everything you have entered and any results already on screen are kept, only the display language changes.
