About dificulty, you can read carefully at Breeding/System (at the end of Process 2) For example: Cloud Dragon has earning rate 5/3, a level 9 gives rate = 5 + 3 * (9-1) = 29

Tropical Dragon has earning rate 12/8, a level 9 gives rate = 12 + 8 * (9-1) = 76

So if we breed these dragons together, Total of rate is 29 + 76 = 105

So let compare how much slots the number 105 unlock (for each dificulty)

Dificulty 1: (Lets count together) [0-50-55-60-65-70-75-80-85-90-95] (100 and 105 is out of the array) so it will fully open 11 slots for this group

Dificulty 2: [0-50-70-90] (110 is greater than 105 so can't unlock this slot) Total slots for this group is 4

Dificulty 3: [0,100] = 2

So the total rate 105 will unlock [11 : 4 : 2] (total 17 slots)

So the chance for Dif_1 = 11/17 = 64.71%

Dif_2 = 4/17 = 23.53%

Dif_3 = 2/17 = 11.76%
