Key takeaways
  • Base inheritance rate
  • Trait families
  • Rare passive floors

Base inheritance rate

40% per parent passive, capped at 4 inherited.

Trait families

Attack passives share a family cap — stacking Ferocious + Musclehead + Lord of the Sea is illegal on the same Pal.

Rare passive floors

Legendary rolls at 5% baseline; use Lucky parents as accelerant.
