# Pal Breed Calc > Free Palworld 1.0 breeding calculator. Pick two parent Pals to see their possible child species, or pick a target Pal to see every parent pair that produces it — built on the fully revised Palworld 1.0 combination table (299 Pals, 136 cross-species special combos, 26 breed-true graph entries) and re-verified against an extracted game-data snapshot. Unofficial fan-made tool, not affiliated with or endorsed by Pocketpair. ## Key facts - Palworld 1.0 breeding is deterministic: each species has a fixed CombiRank; a pair's child is the species whose CombiRank is closest to the average of the two parents' CombiRank (ties go to the higher value). - 136 cross-species special combinations override the formula entirely (e.g. Relaxaurus + Sparkit = Relaxaurus Lux). - The audited breeding graph has 26 breed-true entries: 24 literal same-species rows plus Panthalus and Astralym, which are represented by the engine fallback rule. Relaxaurus Lux and Mossanda Lux are not in this set because they also have cross-species recipes. - Terraria collab Pals (Slimes, Enchanted Sword, Cave Bats, Eye of Cthulhu) can be parents but never hatch as children from a standard pair. - The tier list ranks all 299 Pals on four separate axes: Overall, Combat (attack weighted 0.5, defense and HP 0.25 each), Workers (sum of all twelve work-suitability levels), and Breeding rarity (CombiRank). Tiers are shares of the field: S is the top 5%, A the next 15%, B the next 30%, C the next 30%, D the bottom 20%. - Strongest Pals by raw combat stats: Astralym (200 attack / 200 defense / 200 HP), then Panthalus, Frostallion Noct, Frostallion and Necromus. - Best base-work Pals by total work suitability: Dandilord (28), Silvance (26), Renjishi (24), Lyleen (23) and Dualith (23). Combat strength and work output are close to unrelated in Palworld. - The lowest CombiRank in the game is Astralym at 10, followed by Panthalus (20), Aegidron (30), Shaolong (40) and Bastigor (50). - The current site snapshot covers 299 Paldeck entries. Variant and mutation labels are catalog metadata; mutation behavior is not treated as verified by the parameter-table audit. The 11 Terraria collab Pals share rank 3100 and carry no Paldeck number. - Data source: the revised Palworld 1.0 breeding table, cross-checked against the extracted game-data snapshot (Steam build 24467282) across all 299 parameter records and the published site combinations.
