I just noticed that a new "Obsidian Dragon" has been added to the marketplace. What is the best combination of dragons to breed it. My definition of "best" is a combination which yields the fastest successful result when averaged across attempts. I can see in the marketplace that the breeding time is 8 hours, which is 6 hours 24 minutes with the upgraded BC/EBI. Are there any other dragons with this same breeding time? (ie can I determine that I have bred this dragon successfully based on breeding time?)
The Obsidian Dragon can be obtained by breeding an Earth Dragon or earth hybrid dragon with a Fire Dragon or a fire hybrid dragon. Its breeding time is 8 hours, or 6 hours 24 minutes if you have an upgraded breeding cave or island.
Bear in mind that breeding an Earth Dragon or earth hybrid dragon with a Fire Dragon or a fire hybrid dragon can also yield a Lava Dragon or, before Halloween, a limited edition Bone Dragon, both of which have breeding times of 10 hours, or 8 hours with the upgrade.
As for the best combination, breeding in DragonVale relies a lot on randomness. There is no canonical "best" combination for most dragons. No one seems to know for certain the odds of each outcome from every combination. However, according to this DragonVale Breeding Sandbox, the best combinations (without an Obsidian parent), with a success rate of 29%, would be:
Considering some of these combinations, it would seem all you really need is to have the earth and fire elements.
You breed the Obsidian Dragon from Earth and Fire elements (i.e. Earth and Fire Dragon or their hybrids).
