Special Training is a way to add additional stats to your character’s base stats. In order to achieve these bonus stats you must get FS albums. You can either purchase these from the store under FS Albums, Leveling your account, or through the daily attendance.
The FS Albums are broken down by certain Characters, Commons (all characters), Ranked 1-5 stars, and weekdays. Weekdays are tied into real life and work every day. Only one album per weekday but you can replace them if you draw something better.
FS albums have different characteristics, they range from chance of dunking to player’s speed. Once you have leveled/prestiged your character as high as they go, FS albums are the only way to continue min/maxing your character.
