Astralym
#204Astralym is a special Paldeck entry that exists in the Palworld catalog but is not available through breeding mechanics.
Why Astralym Cannot Be Bred
According to the PalCalc breeding database (v27), Astralym (internal name: WorldTreeDragon) is excluded from the breeding system entirely. It appears in the Paldeck (#204) but has no parent-pair combinations that produce it, and it cannot be used as a breeding parent.
The PalDB catalog lists 299 roster cards, treating the two Gumoss appearances (normal and flower) as a single card. PalCalc models normal and flower Gumoss as separate breeding entities (299 total breedable Pals) and omits Astralym from the breeding database, making it the only catalog-only entry.
Note: As of Palworld 1.0.3 (August 2026), Astralym remains inaccessible through normal gameplay. This may represent a future encounter, event-exclusive Pal, or placeholder entry.
Using the Calculator
Because Astralym is not part of the breeding system, it will not appear in the calculator parent or child selectors, reverse search results, or path solver.
