Pure Dragon = rating (11:11:5)

So your pure dragon is already to high is you want to have an easy chance to get an pure elemental dragon from dificulty 2.

Currently I think an Pure Terra Dragon would be the best option if you want one since that dragon is listed in dificulty 3. How higher your dragon levels, how better.

If you don't want to breed another pure to make you chance more easy to get an elemental that is listed into dificulty 2 than I recommand to take an hybrid or elemental with an as low level as possible.
