Horses all show aptitude to certain jobs/skills. Aptitudes are randomly generated. Horses with an aptitude for a job/skill will take less time to learn it. (Less training images required)
Post below with a link to your horse's registered reference and we will conduct an aptitude test for you.
You do not have to go with the job your horse has an aptitude for! Your horse can only have one aptitude test and this cannot be changed.
Once you have your horse's aptitude, go over to the training programs to get started!
