    What changed

    Most old pairs produce a different Pal in 1.0

    97.7% of comparable pre-1.0 parent pairs changed result

    The comparison uses the same PalCalc data lineage for both versions and aligns Pals by internal name, not by Paldeck number. That avoids false changes caused by the 1.0 roster renumbering.

    Data notes

    Version labels are part of the answer

    Versioned source

    Pre-1.0 uses palcalc v1.17.1. Current data uses v1.17.3, the first corrected 1.0 release line.

    Roster wording

    The game data contains 299 rows. The official roster is 287 Pals; Terraria entries are marked as collab creatures and special Gumoss is kept separate.

    Independent tool

    PalShift transforms public PalCalc snapshots at build time. It does not call another breeding calculator's API.

    Quick answers

    Breeding changes in Palworld 1.0

    Why does an old breeding guide give the wrong result?

    Palworld 1.0 reworked breeding values and special combinations. A guide can still describe a real pre-1.0 recipe while being wrong for the current game.

    Can every old target still be bred?

    No. Some targets are now same-species-only, which means you must catch or otherwise obtain the first one before breeding more.

    Are Terraria creatures included?

    Yes, when the game data allows them to participate in breeding. They are labeled as collab creatures instead of being counted as official Paldeck entries.
