Breeding

Breeding is one of the few (main) features and the core aspects of the game. This concept is introduced by Jubelle during the introduction to the game.

Mechanics
This feature can be found as a small sign inside the barn of the meadow. A pair of monsters currently not busy/tired/pregnant can be selected to breed. The protagonist can also breed with the monster if necessary.

The system has "a family tree", meaning if the monster was born either from the parents or from generations before, they cannot breed with said family members or generations before and will persist even if the parents are sold off. This includes the protagonist.

Note that the gender of the monster does not matter when it comes to breeding, you can have a pair of male or female breeding each other. However, if eggs is what you are after, only the male and female breeding will produce one after several days. Exceptions are Crab and Chimera species, both of which are intersex genders (can either breed a female or be bred by a male).

If the male/female has "Infertile" or "Impotent" negative common trait, they will never be able to impregnate/be pregnant.

Pregnancy
Once the male has finished breeding with the female, the female will be pregnant the next day. During this period of time, you can't send it to do any farming task, or bring it along for dungeon/combat. There will be a blue egg icon above them, and their icon are marked as purple.

Once the pregnancy is over, the blue egg icon turns to gold, and the egg can be taken out to be incubated.

Offspring, Domestication and Colors
See Traits for trait details.

Each monster has their own domestication bar which is automatically determined upon hatching from the egg which doesn't change thereafter, regardless of actions done. If the offspring hatched from the egg has zero domestication, it will immediately trigger a mini-boss fight against it once the egg is hatched.

Every offspring from the parents will also have their own stats inherited from their parents. They will always have their 4 species skill trait and stat trait (with the potential of getting weak variants). If the parents have extra traits, they may get inherited to the offspring, along with the chance of an additional positive/negative trait added that neither parents have.

At rare chance, if the parents are of different species or were bred from different species with other colors, there is a chance the offspring may appear with an inherited color not from their original species at a rare rate. (Currently this only affects Cat, Wolf, Holstaur and Centaur.)

"Graduation Day"
139 days after it has hatched, the monster may run away. There are two methods to ensure they do not run away.
 * Have them in the party (will be shown on save file).
 * Garner 100% loyalty for the monster (this stat is not visible, you have to take a wild guess).

To garner loyalty for the monsters, there are several ways around this.
 * Pet them every day. "Friendly" bloodline trait further increase the loyalty.
 * Feed them food every day.
 * Breed with them. This won't work if the monster has an ancestry bloodline with the protagonist.
 * Bring them to dungeon as ally member of party and fight enemies there.

However, if you do not want the monster to go away, but you do not have the time to garner 100%, you can have their offspring egg gained from them prior to their graduation day.
