    Breeding Eternal Engine onto a Pal

    If one parent carries Eternal Engine, the chance the child inherits it depends on how many different passives the two parents hold between them — a passive both carry counts once:

    • Only Eternal Engine100%
    • 2 passives in all80%
    • 3 passives in all63%
    • 4 passives in all50%

    From PalCalc’s model of the game’s breeding tables (tylercamp/palcalc), which treats every passive alike: the child inherits one to four passives from the pool and may roll up to three random ones, four at most in all. Plan whole pairings in the breeding calculator.

    Stacking and counterparts

    A Pal holds up to four passives and never the same one twice. palworld.wiki.gg: If multiple Passive Skills affect the same attribute, their effects will stack unless otherwise stated. Source
