I decided to play through FFVIII again and right now I'm up to going to Caraway's Mansion. Usually when I'm at this part of the game my Seed Rank drops I was wondering what exactly causes a SeeD rank to increase or drop. I know tests bring it up, but does anything else? Also why does the game usually drop me a rank down around this time. I just came back from the tomb and acquired The Brothers. I didn't leave the cheap and lazy way by bringing up the map and pressing triangle.
I just basically want to know what brings ranks up and down.
