So I've finally made it past Seifer (thanks to the Odin trick) and I now am at the start of disc 4 where I face Adel/Rinoa. Unfortunately I'm stuck.
My team is Squall/Quistis/Zell. Problem is that I leveled up with only Squall, Quistis, and Rinoa so my team with Squall/Quistis/Zell is lvl 69/64/13. My HP is really low at 3029/2639/774 (not sure how to increase besides leveling up). I see youtube videos where they have physical attacks well into the 4 digits but I can't come close to 1K/hit. My strength is GF's but that would hurt Rinoa.
I've been playing this game on and off again for a good 5 years. Now I get to the last disc and I'm stuck with no clear solution. Anyone have tips? I want to finish this game very badly.
