First of all you also have about +/- 3% to get an pure. So wind and crystal can result into one but your chances are just really low. If you can get below the 50 rating you chance will be max however. That wind level 4 + crystal level 4.

Pure is just like legend dragons an wildcard. An wildcard is an dragon that randomly change into another dragon in the calculation. So for example when you breed an wind + crystal you simply breed an random dragon + random dragon  with the pure and legend dragons on your array list.

I list most of them on Breeding/Combinations, some exclusive dragons requires that one of your parents is level 10, 15, 20 or higher. Is listed on their page. Others are just luck (about 1% or lower)
