In the public demo, breeding currently isn't playable. However, there has been no shortage of questions from players as to what this will involve. Although you'll have to wait until Early Access to get your hands on breeding, here's some key information.
The average Goblin isn't much to look at. In fact, even the most remarkable Goblin still pales in comparison to the evolutionary advances of men. No matter how careful a band of Goblins are, they're going to suffer losses when battling the races of men and beast and will always need to seek replacements.
This is where Goblins have the advantage. What they lack in strength, speed, smarts, and looks, they make up for in abundance. Provided they have the right facility, Goblins can multiply with great abandon. The magic all happens in the Warrens of their Lair.
Between adventures, breeding is how you keep your roster of Goblins well stocked. While you could pick up some capable fighters at the campgrounds above the Lair, success relies on the Goblins producing their own unique warriors. Between expeditions, you may go to your Lair's Warrens to assign any two Goblins from your roster to the two breeding slots. If you have more than one Warrens, you could even breed multiple pairs. Breeding will begin once you embark on an adventure.
Upon returning from your adventure, you'll find the goblins ready to spawn. Visit the warrens to see your new Goblin spawns, along with their unique and inherited traits! Some spawns may be better than others, so be sure to keep the best of the lot. Growing up a goblin and assigning their combat class requires food. It's worth noting that breeding is an exhausting process for Goblins, and the more times a Goblin breeds, the longer it will take that specific Goblin to recover and repeat the process.
In Goblin Stone, inheriting genetic traits is simulated. When two Goblins breed, their offspring can inherit the parents' traits. However, you can never be sure which traits will be passed on. All goblins carry both dominant and recessive genes. So it can be entirely possible for two green Goblins to suddenly produce a blue one, provided it's in their genes.
And that's Goblin breeding in a nutshell. So long as you allow your best Goblins time off to breed and spawn, then your Goblin colony is sure to flourish and have better chances versus wayward adventurers.
