Mating

Male and female dragons can mate or breed together to make new eggs. Other than a few personalities, a dragon's lineage has no effect on it. Breeding has a cooldown of 5 days. All breedings will produce an egg.

Some species have requirements on what they're willing to mate with. If a pair is incompatible, they cannot be selected to breed. Neutral dragons cannot breed at all, though some have Special Actions that can create more of their species.

Some hybrid species can only be made by mating two specific dragons together. If a pair can create a hybrid, it will show up in the estimated results as the species or a mystery egg, depending on if you've owned the species before.

## Breeding rarity

Some species are rarer to breed than others. Breeding together two species of the same rarity will have even chances, while breeding different tiers will drop more of the common dragon and less of the rarer one. Breeding two of the same species is 100% chance of an egg of the same species unless the pairing has a hybrid possibility.

* Tier 0: Darknix, God Dragon, Florea, some Special Book dragons
* Tier 1: Most 1600-1700 egg coin dragons and a few hybrids
* Tier 2: Most 500+ dragons, most hybrids
* Tier 3: About 300-500 egg coins, most quest dragons.
* Tier 4: 100-200 egg coin dragons
* Tier 5: lizard dragons (Skink, Crested, possibly Leopard and Girdletail)

## Affecting results

Centipede's Poison and Cupid's Lovestruck Arrow actions can respectively decrease or increase a dragon's chance of breeding true. Their affect is strongest on the more common species of a pair, but has no effect if the pairing only has 1 result. Using Centipede on both parents of a hybrid increases the chance of a hybrid, including cases such as a Chaos form from a Warden or Default Porta, Dianu or Feros.

Rarer breeds frequently have a higher chance of breeding hybrids for semi-flexible species such as Light Spicy and Hydragon.

## Lineage

A lineage is the dragon's parents, grandparents, and so on. Dragons obtained from gameplay or diamonds are generation 1 and have no parents, while dragons bred by players are generation 2 and up.

Lineage length, appearance, and purity is mostly personal preference. However, generation 1 dragons are more sought after because they can't be simply bred by players, and purebred dragons are required for the Pure, Classy, Neat and Noble personalities. Lineage shape is also important for the 4 purebred personalities, as they need to have the maximum amount of dragons the lineage can have.

On the lineage display, the generation count is shown on the left.
