Passive Skill Inheritance
Updated 2026-08-07 · 7 min read
Passive skills are permanent buffs (and occasional debuffs) attached to a Pal. Breeding is the only reliable way to hand-pick them — here's how inheritance works and how to build a flawless Pal.
How inheritance works
When two Pals breed, the baby inherits up to 4 passive skills pulled from the combined pool of both parents' passives, with a chance of also rolling one brand-new random passive. There's no guarantee — it's weighted randomness — so the strategy is to load both parents with the passives you want and re-roll across generations.
Best offensive passives to stack
- Legend — big Attack & Defense boost (legendary Pals only)
- Musclehead — +30% Attack, −Work Speed
- Ferocious — +20% Attack
- Burly Body — +20% Defense
- Lucky — +15% Attack & Work Speed
Best work / utility passives
- Serious / Artisan — +Work Speed
- Swift / Runner / Nimble — +Movement Speed (great for mounts)
- Positive Thinker — slowly heals SAN
Step-by-step: breed a perfect Pal
- Pick 4 target passives (e.g. Legend, Musclehead, Ferocious, Lucky).
- Catch or breed Pals that each carry one or two of them.
- Breed two carriers; keep the baby with the most target passives.
- Pair that baby with another carrier and repeat.
- After a few generations, one baby will roll all four. Breed two of those to lock it in.
Because the child species is fixed by the pairing table, you can chase passives and a specific species at the same time — use the calculator to keep the species on track while you stack passives.
