Breeding inheritance determines which passive skills (traits) a baby Pal can receive from its parents.
If you want “perfect” workers or combat Pals, you’re really trying to build a clean breeding line where parents have only the passives you want.

Recommended background reading:

Key idea: fewer random passives = better results

If parents have extra unwanted passives, those can take up trait slots and ruin otherwise good offspring.

Most frustration comes from breeding with “dirty” parents.

Clean parents = predictable results.
Dirty parents = endless RNG.

What can be inherited

  • Passive skills from either parent
  • A baby can receive a combination of parent passives (depending on available slots and RNG)

You are not trying to “force” traits — you are removing bad options so good ones appear more often.

The reliable method (works in practice)

Step 1 — Start clean

Use parents that have only 1–2 desirable passives each.

Avoid:

  • filler traits
  • mixed-role passives
  • “rare but useless” bonuses

Step 2 — Combine to 2 good passives

Breed until you get an offspring with both desired passives together.

This offspring becomes a new clean parent.

Step 3 — Build to 3 passives

Introduce a second clean line that adds a third passive, and breed until you get 3 clean passives.

At this point, results become much more stable.

Step 4 — Build to 4 passives (optional)

Repeat the same logic:

  • add one new desired passive
  • only from a clean parent
  • stop once you succeed

This “ladder” approach beats trying to jump straight to 4 passives.

Practical tips

  • Keep clean-line parents and don’t overwrite them
  • Label boxes clearly (e.g., Worker Line A, Worker Line B)
  • Decide your target set first:
    • worker
    • combat
    • mount

Breeding without a target is how lines get polluted.

Common mistakes

  • Using parents with too many random passives
  • Trying to get 4 passives immediately
  • Not isolating breeding lines (everything becomes mixed and messy)
  • Optimizing stats before fixing base fundamentals

If your base is inefficient, fix this first:
