OK, so

"It is stated that in order to breed them, "only a few combinations will work". Pure Dragon can be bred from twoLegend Dragons. Since the Pure Dragon is listed into dificulty 2 and that total rating from two legend dragons already unlock all dificulty 2 slots, "

"For any two legend combination, there is a chance of getting a pure dragon in addition to all the other dragons."

How does rating and difficulty affect chance? i.e.,

"you will have a decreased chance when you breed two legend dragons higher than level 4. Since a breeding boost also increase you level. They will decrease your chance for resulting an pure dragon."
