They are there to judge bascially what type of character someone is, & also how u match up to them in a fight during an RPG. For example, I have a high level of strength so I can out-power most & my blows will typically do more damage, but someone who might have higher agility could possibly dodge an attack better than me. As ur points increase, either from board conduct, participating in an RPG, etc. u can add more points to each one of ur skills, as long as ur total number of stats doesn't exceed ur amount of rank points.
