User blog:Leviathan Dragon./Hints and Tips on Breeding Un-breedable Elements

It has came to my attention that some elements cannot be bred together for specific reasons. For example, a Light Dragon cannot be bred with a Dark Dragon, thus the desired result shall not be created unless purchased through the shop by gems and/or gold. So, do you have a specific dragon you want to breed but can't? Here's how to breed them without an issue!
 * Select the dragon from the shop and check it's elements by looking onto its information profile (elements that show up over the dragon through lookouts are a trick and may lead to the undesired result).
 * Hopefully you had your account created before the anniversary! Take the first element as shown in the shop of the dragon you wish to acquire, then place it into the Breeding Mountain/Tree/Sanctuary.
 * Look for the second element (must be a one-element dragon).
 * If the dragon appears as if lightly invisible, that means that you cannot breed it with the dragon you already have selected.
 * Go further down your list of dragons and find a Double-element Dragon. (List of Double-element Dragons: Double Fire, Double Electric, Double Ice, Double Sea, Double Earth, Double Life, Double Metal).
 * The Double-element Dragon will appear as a dragon you can breed with the one you already have in the first breeding stage. Then select the dragon and proceed to the breeding process.
 * Wait or speed up the breeding with gems and then place ingot he Hatchery.
 * When your dragon hatches, you should get the result you had in mind!

And that's it! Note: Some dragons cannot be bred together since there wasn't a released Double-element Dragon of the category. This includes a Double Dark, Double Light, Double War, Double Pure, and Double Legend. Example: you will not be able to breed the Fallen Angel Dragon because of this matter as a Dark Dragon cannot be bred with a Light Dragon.

Hopefully this helps!
