Example of a Holiday multi-clutch

Breeding is an action in Dragon Cave that involves two fully grown dragons of opposite gender. Breeding, if successful, produces an egg of either parent, or in specific cases, a new dragon entirely known as a hybrid. In the past, breeding could produce multi-clutches up to four eggs, but this is now restricted to holiday dragons. Breeding has a cooldown of 7 days.

The success of breeding depends on several factors, the primary being rarity of the dragons in question. Rare dragons are far less likely to produce an egg, though pairing two rares versus one rare and one common has an equal chance of producing. In some cases, the pair may refuse, producing no egg and disallowing the pairing of those two dragons in the future. TJ09 has also confirmed that the longer a dragon goes without breeding, the higher the chance is for a successful breeding to occur.

Bred eggs, unlike the eggs taken from the biomes, can be abandoned immediately, cutting out on the wait time of 5 hours. If an egg is bred but the user has surpassed their scroll limit, the egg is auto-abandoned.

BSAs affecting breeding

Fertility, a BSA (Breed Specific Action) belonging to Purple Dragons, can increase the chances of successfully breeding an egg. It has a cooldown of 14 days.

Breed-only Dragons

The following dragons are hybrids: they can only be obtained through breeding and cannot be found in the cave:

Avatar of Change/Creation/Destruction

These three Avatars can only be produced via specific breeding pairs created using the Guardian of Nature dragon. The avatar produced depends on the elemental affinity of the dragon used to breed with the Guardian of Nature.

Message received and explanation

"The dragons refuse to even go near each other."

This means that the two dragons you tried to breed didn't produce and egg and will also never be able to breed with each other again. It can happen between dragons of any rarity and for the most part is a random occurrence. Breeding Holiday x Holiday or Retired x Holiday any time besides at least one of the Holiday's breeding season will result in a refusal. Refusals also occur when attempting to breed a Neutral affinity dragon to a Guardian of Nature- this is because the Guardian of Nature is also Neutral typed, and they can only be produced via the BSA Summon. Likewise, no Avatar is neutral aligned, so cannot be produced from this type of breeding.

Currently, once a pair of dragons has refused, the refused partner is moved to the bottom of the list of possible mates and is not available to attempt breeding in the future.

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

This means that the two dragons don't want to breed at the time but are capable of doing so in a future attempt. Once a pair of dragons had no interest, the partner is moved to the top of the list of possible mates.

"You attempt to breed the two dragons, but no egg is produced."

This means that the dragons bred successfully but no egg was produced. Once a pair of dragons bred no eggs, the partner is moved to the top of the list of possible mates.

"The dragons breed and produce an egg."

This means they have successfully produced an egg. Once a pair of dragons bred an egg, the partner is moved to the top of the list of possible mates.

"The two dragons breed to produce an egg. However, you realize that you have plenty of eggs and hatchlings to take care of, so you decide to abandon it."

This means they have successfully produced an egg, but you were already at your scroll limit before breeding, so the resulting new egg has been automatically sent to the Abandoned Page. This is the most common way that accidental auto-abandons occur in.

Past Glitches

In Halloween of 2013, a user experienced a multiclutch breeding glitch by pairing a Guardian of Nature with a Black Marrow, resulting in 4 Guardian of Nature eggs. It is unknown how this issue was resolved.
