Sabers have 11 physical mutations, 5 of them are Mane Mutations, 5 are Tail Mutations and the last one is the Fangs Mutation.
While it is possible to combine a Mane and a Tail Mutation, it is not possible to have two or more Mane / Tail Mutations at a time!
 
These Mutations are only available for the regular Saber, Ancient Sabers may not have any of them!
 
The Smoke Mane / Tail and the Fangs Mutation can only be inherited from Umbru, the Goddess of Moon and Stars or from other Sabers having them. They cannot be chosen for any type of custom!
