# Breeding

Breeding allows players to pass traits, abilities, and personalities from one generation of monsters to the next. It is a **long-term progression system** that rewards investment, strategy, and experimentation, while adding depth to Spellborne’s monster ecosystem.

***

### **Overview**

* Combine two monsters to produce an egg that hatches into a new offspring.
* Offspring inherit attributes, mutations, and trust influences from their parents.
* Breeding introduces both **predictable inheritance** and **unpredictable variation**, ensuring no two monsters are ever exactly alike.

***

### **Core Mechanics**

#### **Requirements**

* Two compatible monsters (certain species, traits, or egg groups).
* Breeding facility access (Daycare or special in-game location).
* Resources such as crops or crafted items to support breeding.

#### **Inheritance System**

* **Base Stats**: Offspring inherit a percentage of their parents’ HP, Attack, Defense, etc.
* **Traits & Abilities**: Some abilities pass directly.
* **Mutation Paths**: Certain breeding pairs can unlock hidden mutations or unique variants.
* **Personality & Trust Factors**: Likes, dislikes, and trust growth rates may also carry over.

#### **Eggs & Hatching**

* Eggs require time or resources to hatch, and usually take around 3 hours to hatch.
