Palworld 1.0 Breeding Data: 44,851 Combos

Source revision

PalCalc game-data export · View source

Versioned data, visible limitations

• Game version: PC/Steam v1.0.2.101103
• Recommendation scores are calculator rules, not official game ratings.
• Mount scoring uses a conservative manually reviewed mount list; unconfirmed new mounts are not scored as mounts.
• The planner models species outcomes only and does not simulate mutations, passives, IVs, egg time, or probability.
• One gender-dependent parent pair can produce two different children and is clearly labeled in results.
• This is a Palworld v1.0.0 dataset snapshot with 44,851 source-derived outcomes. Its breeding data was verified compatible with the public v1.0.1 patch on 2026-07-17; the original snapshot label is preserved because it was not re-exported from that patch.

Download the audited breeding table

The downloads contain stable Pal IDs and every audited parent-to-child outcome. They exclude images and recommendation scores, so the file stays focused on reproducible breeding facts.

• JSON — records plus metadata and limitations (8,049,960 bytes; SHA-256 9f558802ed3fa14b52c352d18a05cd40b295e636ccca249376293e80dc1643c4)
• CSV — one row per breeding outcome (2,128,682 bytes; SHA-256 db4e0e2b755ed3c01ef61744dfcc66c1af320ad444b4c0f47af687a3cf8f0b74)

Both files are generated deterministically from the pinned source revision on July 17, 2026. The SHA-256 values above let downstream users verify that a downloaded copy is unchanged.

Palworld v1.0.1 compatibility audit

This remains a v1.0.0 snapshot. On July 17, 2026, it was checked against the first public PC/Steam v1.0.1 patch after release. The patch notes list save-data and burning-status fixes, not roster or breeding changes. Exact game-data exports from the builds before and after that patch also have identical Pal and breeding checksums.

Evidence and reproducibility

1. Pocketpair’s official v1.0.1 patch notes list no breeding-table or roster change.
2. The dataset is pinned to PalCalc commit 8b7e2f779e47, documented by PalCalc pull request 187.
3. Reproducible exports for Steam builds 24088465 and 24181105 have matching manifests: Pals 57fb4bf837061c11… and breeding dc39e4c8646eaa7f….
4. Run pnpm run validate:data in the Palweave source repository to verify counts, references, duplicate/conflicting recipes, parent-order symmetry, reverse indexes, localized stable IDs, and replayed shortest-path steps.

Audit result

• 287 player-visible canonical Pals; 299 calculation records; no duplicate stable IDs.
• 44,851 outcomes: 44,603 ordinary and 248 fixed special.
• No unknown parent or child references.
• No duplicate recipes or conflicting unordered pairs.
• All 299 calculation IDs map to 17 supported interface languages.

Cultivation decision derivations

Pal guides and calculator choices reuse the same structured Pal records as the breeding engine. Work labels come from positive work-suitability levels, sorted by level and then a fixed field order. Combat and mount labels use the existing versioned model roles and conservative reviewed-mount set. A breeding-connector label appears only when a Pal reaches the dataset’s upper quartile for distinct direct offspring.

Important offspring are deduplicated by child. Palweave keeps the easiest verified mate for each child, then sorts with a transparent formula: 50% modeled general utility, 25% normalized distinct-child reach, 15% modeled rarity, and 10% mate obtainability. Stable Pal IDs break exact ties, so results are reproducible. The numeric score is not displayed as an in-game tier or official rating.

The pinned export does not contain verified partner-skill text or a reliable Pal-to-element mapping. Palweave therefore marks the partner-skill detail as unavailable and does not invent partner descriptions, element facts, passive-skill advice, or tier labels.
