Breeding and Passive Skills
Breeding allows you to combine two Pals to produce a new egg. The resulting offspring inherits stats and passive skills from its parents. Mastering this system lets you create perfect worker Pals or unstoppable combat companions.
Setting Up the Breeding Farm
Unlock the Breeding Farm in the Technology tree at level 19. Build it in a spacious area within your base. You need one male and one female Pal to start the process. Pick up the desired parents and throw them directly into the Breeding Farm enclosure to assign them.
The Breeding Farm requires Cake to produce an egg. Bake Cake using a Cooking Pot. Each Cake costs 5 Flour, 8 Red Berries, 7 Milk, 8 Eggs, and 2 Honey. Wheat must be farmed at a Wheat Plantation and milled into Flour at a Mill. Assign the following Pals to a Ranch to automate your ingredient supply:
| Ingredient | Ranch Pal |
|---|---|
| Eggs | Chikipi |
| Milk | Mozzarina |
| Honey | Beegarde |
| Red Berries | Caprity |
Place the finished Cake into the wooden box attached to the Breeding Farm.
Understanding Combinations
Breeding two different species often results in a completely different Pal. The game uses a hidden numerical value assigned to each species. The offspring's species is determined by averaging the values of the two parents.
Experiment with different pairs to discover new Pals. Combining an early game Pal with a mid game Pal can yield a surprisingly strong creature. Breeding two Pals of the same species always produces an egg of that exact species.
Some special variants, like Frostallion Noct or Jormuntide Ignis, require specific parent combinations to breed.
Passing Down Passive Skills
Offspring inherit up to four passive skills from their parents. If the parents have excellent traits like "Artisan" or "Musclehead," the child has a high chance of acquiring them.
To breed a perfect combat Pal, isolate the desired traits. Find one parent with "Musclehead" and another with "Ferocious." Breed them repeatedly until you get a child with both traits. Introduce a third parent with "Burly Body" into the bloodline. Continue this selective breeding process until you hatch a Pal with all four desired combat passives.
Avoid breeding Pals with negative traits like "Glutton" or "Slacker." These negative traits pass down just as easily as the positive ones and ruin the offspring's potential.
For base workers, the optimal trait stack is Artisan (+50% Work Speed), Work Slave (+30% Work Speed, -30% Attack), and Serious (+20% Work Speed), which combines for a total +100% work speed increase. See Base Building and Automation to understand which work suitabilities matter most.
The Hidden Breeding Power Value (BPV)
The breeding engine does not use genetic inheritance. Every Pal species has a hidden "Breeding Power Value" (BPV) ranging from 10 to 1,500. Lower numbers represent rarer Pals.
When you breed two parents, the game calculates the offspring using this formula:
Offspring BPV = Floor((Parent A BPV + Parent B BPV + 1) / 2)
The game then selects the Pal species whose native BPV is closest to that result. This means breeding two high-tier Pals does not always produce a high-tier offspring. The math drives results toward the median (around 500 to 600 BPV). For example, breeding a Cattiva (BPV 1460) with an Anubis (BPV 570) produces a Robinquill (BPV 1015), not another Anubis.
Continuously breeding random pairs without checking BPV values causes generational decay toward mid-tier Pals. Use an online BPV calculator to plan your target combinations before wasting Cakes.
