A Special Cake makes the egg inherit 4 of the parents' passives. These parents carry 4 between them, so every egg gets all 4 passives you want.
How the odds add up
| Rolled count | Chance | Inherited | Has all wanted | Exactly |
|---|---|---|---|---|
| 1 | 40% | 1 | <0.01% | <0.01% |
| 2 | 30% | 2 | <0.01% | <0.01% |
| 3 | 20% | 3 | 0.43% | 0.43% |
| 4 | 10% | 4 | 100% | 100% |
Only from the parents (ignoring random additions): 10%.
How passives pass to an egg
- The parents' passives go into one pool, and the egg inherits 1, 2, 3 or 4 of them, with chances of 40%, 30%, 20%, 10% Datamined codeDerived from the game code, not from a data table.. It never inherits more than the pool holds.
- Then 0 to 3 random passives may be added, with chances of 40%, 30%, 20%, 10% Datamined codeDerived from the game code, not from a data table., up to 4 passives in total.
-
Special Cake: The egg always inherits 4 of the parents' passives, or all of them if they have fewer. It also inherits every active skill both parents have equipped.
The child species is the same as without a cake.
- "Has all wanted" counts eggs that carry every passive you ticked, with or without extras.
- "Exactly these" counts eggs that carry those passives and nothing else.
Passives that are never added at random (for example species-only or World Tree passives) can only come from a parent.
How we know Datamined codeDerived from the game code, not from a data table.
The inherit and random-add weights are game settings. The order the game applies them in comes from the game code (what the labels mean).
