Request :Changing attribute points on original charactors

I think the file to use is parameter_spec_char.psc . But i have no clue of understanding how this works . I know this is possible because the original characters sometimes go beyond level 80 in some missions. So if someone can help me out to figure out this,it is greatly appreciated.

I know you can change custom charactors attribute points using the save editor . but this probably doesnt have to do with the save. but something along rthe lines is what im looking for. I want to make cpu opponents stronger
