I'm a bit down at your level! I have all the skills for Kimahri, Auron, Rikku and Tidus! My HP is about 1000 down, and MP 50-100 down from yours!

Im at 31 hours and at the point where to fight Yunalesca! I found Seymour at Mt. Gagazet quite easy, i cast Hastega on everyone and did there overdrives and then summon aeons and used there overdrives and it took me about 5 minutes to defeat him! =) XD
