Horse Breeding (sage ability)
Enables skill in the assessment judgment and the practice of selective breeding of horses. The study incorporates the method by which specially desired characteristics in domesticated horses are improved through their offspring, granting also a superior skill in ensuring a healthy pregnancy and successful foaling. The character is able to recognize the pedigree of horses upon examination, determining with sight and skill those characteristics that make a specific horse a good candidate for breeding. This knowledge is then applied when inducing a stallion and a mare to couple and reproduce — not only so that their pre-existing traits can be shared by the offspring, but also to ensure the highest possible chance of a giving pairing producing a positive-mutation.
Pedigree
For game purposes, the pedigree of horses is simplified for the purpose of playability. Every horse is scaled according to its health, robustness, speed, courage and fertility. Health registers the resistance of the animal to disease and fatigue; robustness, the overall strength and endurance of the horse as a working animal; speed, its value as a racehorse; courage, its temperament when exposed to combat; and fertility, the ease with which it procreates and the chances of it producing a positive mutation.
All horses, wild or domestic, already have specific characteristics relating to their type. These types are the results of thousands of years of breeding; any horse is, therefore, measured against its type with regards to its pedigree. Thus, the measure of a working horse's robustness is applied to a different template than that of a pony.
Each of the five characteristics above is rolled for on 4d6, the average of which is 14. Each point of deviation from 14 indicates a 1% deviation from the standard template that applies to each horse type. For example, a domestic pony has 1-10 hit points; this initial number indicates the pony's bodily units. If we roll on 4d4 and gain a result of 16, then the pony's health is 2% above normal; this does not increase the pony's hit points, but does make the pony 2% more resistant to disease. A similar result against the pony's robustness would enable a 2% greater load that could be hauled or carried; if applied to speed, the pony would be 2% faster; in battle, it's morale would be improved by 2%; and with regards to fertility, it would be 2% more likely to reproduce and 2% more likely to produce a mutation in its offspring.
This seems a slight adjustment; however, when applied to millions of domestic horses worldwide, remarkably slight improvements have the power to win races, permit a rider to survive a fight or can be applied a permanent adjustment in a horse type — the method by which wild horses were eventually bred to a type with 4+4 hit dice.
Mating
This formula enables the game to reproduce a wide distribution of specific horses, potentially adjusting a horse's price or giving a tremendous credence as to why persons might sincerely treasure their beloved horses. Breeding is therefore easily managed in game terms, since it is presumed that the horse breeder is fully aware of the horse's pedigree as described above. Therefore, the stallion and mare are selected; the resultant offspring will randomly assume the pedigree of one horse or the other — and in each case, the combined mutation % (d100) is rolled for the offspring. If the mutation occurs, then the highest two pedigree characteristics of the offspring will be raised by 1-2 points. If more than two pedigrees show as the highest number, then randomly roll to determine which two pedigrees are raised.
If "00" (or 100) is rolled on the mutation die, then the mutation is a negative. If so, two random pedigree characteristics (regardless of importance) are each lowered by 1 point.
Obviously, the bloodlines of stallions and mares must be kept clean. 2nd cousins will increase the chance of a negative mutation to 10%; 1st cousins, to 20%; and between siblings or direct ancestors to 40%. Normally, horses will not willingly mate between siblings and direct ancestors.
