Palworld breeding guide: how the child is picked

The rule

1. 

   Special combo

   If the parents form one of the 81 special combos, that child hatches. Nothing else is checked.

2. 

   Same species

   Two Pals of the same species hatch that species.

3. 800 1570 1190

   Breeding power

   Otherwise the egg is the pool Pal nearest the parents' average breeding power. A tie goes to the higher breeding priority.

Try it on the breeding power line

Pick two Pals to see both on the full scale (20 to 3,100) and the pool Pals nearest the midpoint. The example, Kitsun Noct + Felbat, is a tie.

Parent A

Parent B

Genders

A male, B female A female, B male

Kitsun Noct Male Felbat Female Bulldosu Kitsun Noct (breeding power 800) plus Felbat (breeding power 1570) gives Bulldosu: the midpoint is 1185 and Bulldosu is the nearest Pal in the breeding pool, at breeding power 1190.

Rarer, strongerMore common

Breeding power 800 and 1570 give a midpoint of 1185. The nearest Pal in the breeding pool is Bulldosu at 1190, 5 away.

That is a tie with Wistella (1180). The higher breeding priority wins: Bulldosu has 119,000, Wistella has 118,000.

A lower breeding power means a rarer Pal. The game files call it CombiRank.

Two common parents land near the common end, so you need at least one rare parent to reach the rare end.

Game data Every breeding power in the current data is a multiple of 10, so the "+1" in the midpoint never changes a result.

Pairs decided by power

A midpoint that ends in 5 can sit exactly between two pool Pals. The game then hatches the Pal with the higher breeding priority.

That priority is breeding power times 100 for every pool Pal, so the more common of the two always wins.

• Kitsun Noct Felbat Bulldosu Ground

  Normal rule

  Midpoint 1185: Wistella 1180 vs Bulldosu 1190

• Fuddler Suzaku Souffline Grass

  Normal rule

  Midpoint 1995: Lullu 1990 vs Souffline 2000

• Jormuntide Ignis Braloha Wumpo Botan Grass

  Normal rule

  Midpoint 600: Jormuntide 590 vs Wumpo Botan 610

Special combos come first

81 fixed pairs always hatch one particular Pal. Apart from mutations, those children hatch only from their combo or from two of themselves.

A skipped neighbour

Anubis Beakon Relaxaurus Dragon Water

Anubis (480) + Beakon (1690) has a midpoint of 1085. Broncherry Aqua (1080) is closer but is a special-combo child, so the egg is Relaxaurus (1090).

See all of them on the special combos list.

Gender

Game data Every pair needs one male and one female. Only one pair of species changes its child with the parents' genders:

• Katress Female, required Wixen Male, required Katress Ignis Dark Fire

  Special combo
• Katress Male, required Wixen Female, required Wixen Noct Fire Dark

Everything else can still be a parent but never hatches from the breeding power rule. Jetragon + Lamball gives Bushi (midpoint 1560).

Cakes and mutations do not change breeding power

Eggs that mutate Datamined code

1%

With Extravagant Vegetable Cake Datamined code

3%

No cake shifts the midpoint, so the species stays the same. Cakes change the egg count, stats, passives and mutation chance (breeding cakes).

A mutated egg hatches a Pal picked by a different formula. It can be a Pal this pair never gives otherwise.
