Breeding Calculator

Put a male and a female Pal in the Breeding Farm with a Cake and they produce an egg. Which species hatches is fully deterministic: every breedable Pal has a hidden combi rank (in v1.0 they run from 30 to 3080 - lower means rarer and generally stronger), and the child is decided by the parents' average rank:

child rank = floor((rank A + rank B + 1) / 2)

• Closest rank wins. The child is the Pal in the generic breeding pool whose combi rank is closest to that target.
• Ties go up. If two Pals are exactly the same distance away, the game picks the one with the higher combi rank (most third-party calculators get this backwards). If two Pals somehow share a rank, the lower Paldex number wins.
• Same species breeds true. Two Lamballs average to Lamball's own rank, so the child is always a Lamball. The same holds for every species.
• Special combos override everything. 136 fixed cross-species recipes plus 121 self-recipes (both below) ignore the rank formula: a specific pair always produces a specific child.
• Variants are special-only. Elemental and regional variants (the "B" Paldex entries like Mossanda Lux) are excluded from the generic pool - the rank formula can never produce one. You get them only from their special combo or by pairing two of them.
• Gender-locked recipes exist. Katress + Wixen is the only pairing where the parents' genders decide the child: male Katress + female Wixen gives Wixen Noct; female Katress + male Wixen gives Katress Ignis.
• Legendaries only breed true. Jetragon, Frostallion, Necromus, Paladius and their kin have no combi rank at all - two of the same species is the only pairing that works.

Everything on this page - ranks, pools, special combos and the calculator itself - is extracted from the v1.0 game files and runs the same algorithm as the game.
