This forum is based on help on horses for mo'creatures.I posted 2 solutions to 2 problems that you would probably really want to know the solution.I will also be explaning the different tiers.
1st Problem:Only a couple types of mo'creatures horses are spawning.A light brown and blond haired horse,a redish brown and white horse,a plain redish brown horse,a plain gray horse and a zebra.
Solution:Jeb decided to add horses to minecraft because of ZrZhark and his mo'creatures.When you get the mod,you will notice different types of vanilla horses because mo'creatures actually added those vanilla horses.So,if you want a zorse,you breed a certain horse from the list of mo'creatures horses that I put in the problem with a black vanilla horse.In the process of breeding,you will need to breed the black horse two times.
2nd Problem:When I finally get a unicorn and a Pegasus,I try to breed them to get a fairy horse.Like usual I have to feed them 2 essences of light and hearts are supposed to appear.They did not get the hearts and did not breed a fairy horse.
Solution:This doesn't really do anything but its a solution as in telling you whats wrong if your curious.Well,the fairy horses haven't updated to 1.6 yet.I've been waiting and I really want a fairy horse and probably same with you guys.Just be patient and wait for the fairy horses to update.
Tier 1: Tier one horses spawn naturally and are at the lowest,0% rare and at highest,36% rare.
Tier 2: Tier two horses you usually have to breed once to get and are at the lowest,37% rare and at highest, 56% rare.
Tier 3: Tier three horses you usually have to breed twice to get and are at the lowest,57% rare and at highest,76% rare.
Tier 4: Tier four horses are special horses and you have to breed a lot to get it.They are at the lowest,77% rare and at highest,96% rare.At night,wild special horse that cannot be tames are 1% rare.
For all of you who had trouble with mo'creatures 1.6.X,I hope this helps a lot for you guys!
