Breeding

Intro
Breeding is a feature which enables the player to reproduce their dragons, while generating different varieties of dragons. This allows players to acquire dragons without resorting to buying eggs with gems. Other purposes of breeding are:
 * Complete collections in The Book of Dragons.
 * Acquire better dragon for Combat & Earning.
 * Generate income by selling hatched dragons.

Breeding Concepts
Breeding involves the following concepts:

1) One pair of dragons always produce one egg.

2) Dragons are hermaphrodites (both male nor female). Therefore any dragon can breed with any other dragon, provided the following limits:
 * Dragons must be level 4 or above to breed.
 * Dragons which are busy in training or breeding elsewhere cannot be used for breeding until they are available again.
 * Basic elemental dragons cannot breed with basic elemental dragons of the opposite element.

3) The resulting egg usually hatches into a dragon which possesses a mix of elements - one from each of its parents. Exceptions exist when legendary dragons are bred.

4) The breeding time of any given combination of Dragons is equal to the hatch time of the result dragon. (See Eggs for hatch times.)

Breeding Guide
Elemental= Basic elemental dragons have only one element, and can be bought for gold at the store. Breeding two dragons of the same element will always produce an elemental dragon of that same element. On the other hand, when two different elemental dragons are bred together, the resulting egg almost hatches into a hybrid everytime. Hybrid= There are generally two varieties of hybrid dragons that can result from breeding different elemental types together. The resulting hybrid does not depend on the order which the parents are selected, although it is likely that some hybrid eggs are more common than others. Hybrids may be bred together to generate more hybrids. If both parents share at least one element, an elemental dragon may also be produced. Breeding an elemental with a hybrid guarantees that the new dragon hatched will possess that element. Two hybrids which carry opposing elements may sometimes produce a Rare Hybrid. Rare Hybrid= Basic elemental dragons of opposite elements cannot breed directly with each other. Instead hybrid dragons carrying each element must be used. Breeding together rare hybrids can result in any of the dragons expected from breeding together two regular hybrids. Occasionally, 2 rare hybrids can result into an Legendary Dragon. Legendary= Legendary dragons are bred from two rare hybrids. When used in breeding, legendary dragons function as 'wildcards'. Breeding a legendary dragon with non-legendary dragons produces a random dragon which always carries at least one element from the non-legendary parent. Breeding together two legendary dragons results in a random egg. There is however a significant possibility of acquiring a Pure type. Pure= It is stated that in order to breed them, "only a few combinations will work". Pure Dragon can be bred from two Legendary Dragons.

Weakness effect breeding
Example:Pirate Dragon is a dragon that weak to Pure Dark Dragon and Petroleum Dragon is a dragon that weak to Pure Water Dragon Example:You have Dark Fire Dragon is weak to Pure Dark Dragon it means Dark and Fire and your goal is get the Vampire Dragon it means Fire and Dark.
 * Always see the pure weakness of a dragon.
 * Remember the mixture of the dragon that you hatched. When the pure's weakness is searched,The pure's weakness put at the Dragon 1 and the next mixture.
 * The Rare Hybrids,Legendary and Pure are doesn't exist at the techniques.

Breeding chart: Basic, Hybrid and Rare Dragons
Basic dragons are found from top left to bottom right. Rare Dragons are found from bottom left to top right: They cannot be combined directly from their base elements. Two basic dragons of the opposite elements cannot be bred, and therefore, a presence of at least one hybrid dragon with the opposite elements of the basic dragon OR two hybrid dragons with opposite elements are be needed.

Normal Letters - Hybrids

Bold Italic Letters - Pure Dragons

 Bold Underlined Letters - Legendary

Strikethrough Letters - Any Dragon  Understanding this chart will make breeding a Rare Dragon much easier as all possibilities are visible, Examples:

The breeding chart is mirrored along the diagonal of pure element dragons.
 * 1) An Armadillo (first column, last row) can be bred with any Hybrid from first column combined with any Hybrids in the last row.
 * 2) A Cool Fire (second column, seventh row) can be bred with any Hybrid of the second column combined with any Hybrid in the seventh row. However, your chances may depend on the combination chosen.

Breeding Times
The breeding time was according to the longer hatching time among the 2 dragons you choose for breeding(See Eggs for hatch times.)

Breeding Rare Hybrids
There are about as many potential combinations to Breed the Rare Hybrids as you can think of, but we will just briefly go over some of the simple ones. These are NOT the only possibilities--just a few that you have access to earlier in the game. Gummy= An Gummy Dragon exist out of the elements Plant and Electric. So in order to breed one you will have to combine those two elements. Note that basic element dragon can't be breed together.

Trivia

 * Approximately 6:30, September 23, 2012 in Tuesday, an official update in Dragon City's Facebook page showed that Rarity Boost raises the chances of getting a Rare, Legendary or Pure Dragon is increased by 50%.
 * The breeding times have been changed, before the breeding time got calculated by counting the parents breeding time together. Now the breeding time will be similar as the hatch time.
 * Since August 2012, there is a significant possibility of acquiring a Pure type from two legendary dragons.
