Rainbow Dragons are one of the rarest dragon species in Dragonvale. The chance that it will be possible to grow one is very small, but many combinations are possible. If you're extra lucky you might get a Double Rainbow Dragon, which is by far the rarest dragon in the game.
Step 1. Remember the chances are slim
If you cross two dragons that meet the criteria, there is a 1% chance that the result will be a Rainbow Dragon, which increases to 2% with the Epic Breeding Island. The chance of getting a Double Rainbow Dragon is 0.5% (1% with the Island). There is no way you can increase this chance. If you don't manage to get a Rainbow Dragon by crossing, just keep trying until you finally succeed.
Step 2. Level up your park to level 11 or higher
You will need to earn experience points and level up your park to level 11 before you can start breeding Rainbow Dragons. There are a number of ways to earn experience points and increase your level:
- Achieve your daily goals.
- Hatch dragons.
- Build new buildings and habitats.
- Complete Colosseum events.
Step 3. Build an Epic Breeding Island
Normally you have a 1% chance of getting a Rainbow Dragon, but you can increase this to 2% if you use an Epic Breeding Island instead of a Breeding Cave. The Epic Breeding Island costs 125 Gems and you must be at level 13 to build it.
You can upgrade the Epic Breeding Island to an Epic Breeding Sanctuary, which costs 225 Gems. This won't increase your chances, but it will reduce the growing time by 20%. This will speed up the process
Step 4. Have two dragons, each with two unique elements, reach level 4 or higher
To be able to interbreed with a dragon, he must be at level 4 or higher. You can level up a dragon by feeding it or by using Gems.
It is said that if both dragons are at level 11-20, the chance of getting a Rainbow is increased. However, this has not been verified
Step 5. Click on your Epic Breeding Island and then click on 'Breed'
This will start the growing process.
Step 6. Select two suitable dragons that together have at least four unique elements
This is the only requirement for a chance at breeding a Rainbow Dragon. It doesn't matter which dragon has which elements, as long as four unique elements are used. This means that there are about 30,000 different combinations that can result in a Rainbow Dragon. The probability of creating a Rainbow Dragon is not affected by the choice of elements. A few possible combinations include, but are by no means limited to:
- Panlong + Seaweed
- Crystal + Blue Fire
- Current + Flower
- Blazing + Swamp
- Love + Swamp
- Flower + Plasma
- Scorch + Seaweed
- Firefly + Seaweed
- Crystal + Lichen
Step 7. Note the growing time
If you select two dragons and start the breeding process, it will display how long it will take to complete the process. If the time displayed is 48 hours, or 38 hours and 24 minutes, it could be a Rainbow Dragon.
Step 8. Wait for the growing process to complete
It will take a while for the growing process to complete, and you won't be able to see the result until this process is complete. You can pay Gems to speed up the process, if you wish.
Step 9. Wait for the egg to hatch
Rainbow Dragons will have an incubation period of 48 hours. You can pay Gems to speed this up as well. If the egg is striped in the colors of the rainbow, you have a Rainbow Dragon.
Step 10. Let the egg hatch
If you are lucky you have just received a Rainbow Dragon. If you're extra lucky you'll get a Double Rainbow Dragon! Don't worry if you haven't received Rainbow Dragon. The chance of this is very small. You will probably have to cross two dragons many times before you get a Rainbow Dragon.
Step 11. Restart the breeding process if you have not made a Rainbow Dragon
If you haven't made a Rainbow Dragon you can just repeat the breeding process. Since most element types don't affect the odds, you can just cross the same two dragons again until you manage to make a Rainbow Dragon.
