I'm stuck at sin head boss fight, I don't know what to do. I've been grinding on omega ruins now since I rushed mt gagazet after dying and losing most of the progress there, but no matter how much grind it doesn't feel like it is meaningful.
Auron and Tidus are both 40+ in strength but don't deal like 5k damage or more. I haven't been using Wakka since he also felt like was really weak.
Lulu and Yuna are almost 60 in magic, it's good and just got Holy on Yuna so I'm dealing good damage.
I still haven't unlocked hastega (still grinding)
I don't know if every character should be dealing 9999 damage by this point, if I am missing an insane weapon or something but a lot of videos I watch the characters do deal so much damage, but mine deal almost 9000 rarely.
