Looking for the fastest combination to hatch the Rainbow Dragon. In my opinon, it no longer holds the number one spot for "best dragon to have" - but by any measure it looks awesome and is great to have in your collection. It does take a while to get, so if you want to get one as fast as possible check out the combinations below.
Breeding Pair: (Firefly OR Scorch) + (Seaweed OR Swamp)
Breeding Time: 48 hours or 38 hours 24 min (with upgrade)
Availability: Unlimited
Type: Rainbow
Price: 2,500 Gems (Practically the definition of "no way")
While it may seem to take forever to get one of these, you will eventually luck into it while breeding other dragons. In fact, you may one day curse your "good" luck when you pick up the long breed time of a Rainbow as you try to breed some other Limited Dragon. Focus on the long haul, and if you get frustrated, just take a break. Sooner or later, fate will smile on your breeding edifice - have no fear.
