Breed

Once a dragon is fully grown, you have the option of breeding them with a fully grown dragon of the opposite gender. Doing so may produce one to four eggs. This egg will usually be of the same breed as either of the parents (the geode dragon and Two-Finned Bluna being the only exceptions as they can have differant parents (see below for pairings).

Pairing Dragons
Not all dragons will breed with another species.Two-Headed dragons and Pygmy dragons will only breed among dragons of the same species, and Ochredrakes will only breed with other drake subspecies.

Message received and explanation
"The dragons refuse to even go near each other."

This means that the two dragons you tried to breed were rares. In order to keep rares rare it has been made nearly impossible to breed a rare with another rare dragon

"The dragons don't really show much interest in each other"

This means that the dragons don't want to breed at the time but are capable of doing so.

"The dragons breed but no egg is produced."

This means that the bred successfully but no egg was produced.

"The dragons breed and produce (an, two, three, four) egg(s)."

This means you have succesfully bred an egg(s).

Geode Dragon
The Geode Dragon can only be made by pairing Stone, Pebble or Geode dragons.

Two-Finned Bluna
The Two-Finned Bluna can only be made from the following:

Skywing x Deep Sea

Skywing x Water

Bluna x Comon Dragons

Outcome
Once you have found two matching dragons and bred them, they may produce between 0 and 4 eggs. These eggs may be of different breeds, such as half being the same as the father while the other could be like the mother, or all may be the same breed. You may only pick one egg out of the batch; the others will be abandoned automatically and can be picked up by others.

Breeding will have a higher success rate if there are few eggs in the abandoned page.
