Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, don’t be afraid to mix things up and experiment with different paths for your characters. It can be beneficial to focus on each character’s strengths but also dabble in other areas to make them well-rounded.

For side quests, make sure to visit every location multiple times to ensure you don’t miss any hidden quests or items. Don’t forget to participate in the Monster Arena challenges for some great rewards and tough battles that will test your skills.

As for character builds, consider customizing each character based on their unique abilities. For example, Tidus can excel in speed and agility, while Lulu can focus on powerful magic spells. And don’t underestimate the importance of abilities like Quick Hit and Ultima for those tough boss battles. Happy exploring!
