hello, I think we can make highest chance to get it by using Pure Lv4-5 + Dark Lv7.

Why? Because Pure Dark dificulty 2, then we will have to make total rate between 230-299. So a Pure Lv4-5 rate is 180-220, and a Dark Dragon Lv7 rate is 52 => total is 232-272.

I do this way, and 1st time fail with a dark hybrid (Zombie - 12h, my missing piece in the book), 2nd fail also with dificulty 2 dark hybrid (Hedgehod - 12h, but good), and 3rd time success with 48h breed. xD My point is to make sure the group of the Pure Dark is highest chance (40%)
