well i didnt level up untill disc 3 i was about level 25 for each character except for squall who was aout level 30. I got everyone to junction the str bonus e.t.c and then levelled them up to 100 without removing them. Then when i junction str60%e.t.c they got 255 for most stats. (shockwave pulsar did about 400 damage because my spr was 255)
