Do you mean is it quite easy to breed crystal hybrids? If so, the answer is no! Lol. You use your crystal unicorn then an animal with the elements of the creature you want. But hybrids are ultra rare so they are pretty difficult to get, it's all luck. I got two citrines in under a week! But before that, I can't remember my last one! I have been after the Kirin for ages and have not had any luck there! Hope this was helpful!
