Qilin is a male divine unicorn who is one of the divine Chinese horses. He can breed with all your female unicorns, except your female donkey unicorns. The conditions are the same as a covering between 2 unicorns of the same breed.
If the foal bred is a unicorn, it will be born with the Qilin bonus that gives them 15 points in all skills.
For each completed covering, Qilin earns skills points that you can apply as you wish.
Furthermore, on the 1st of every month, Qilin gives you a Fertility Wand provided you logged in the day before.
