When I did my challenge, I tried to not use any summons, although I did give in and use Bahamut a few times. I think the hardest part is leveling up Cloud's Limits in the beginning to beat Reno.
Although I don't believe I ever finished it. I think that was when Valkyrie Profile 2 came out. I should try loading up that save file...
