I might be retarded.
How do you spark farm? is it completely RNG? I wanna try starting doing runs with a "purpose" on mind so I can actually get better and better horses
But I truly do not understand how even I should start runs and what lineage I should use.
I understand that the more stars in something the better, so 3* speed is what you are looking for if you want speed and so on.
But how does it work for other shit like aptitudes for distance or style?
