Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, make sure to focus on each character’s strengths. For example, Tidus is great for speed and agility, so prioritize those nodes for him. Don’t be afraid to branch out to other areas to make your characters more versatile.

For side quests, be sure to complete the Monster Arena challenges for some great rewards and tough battles. Also, don’t miss out on the Celestial Weapons quests for each character – they’re powerful and worth the effort.

When it comes to character builds, experiment with different paths on the sphere grid to find what works best for your playstyle. Mixing magic and physical abilities can create well-rounded characters. And don’t forget to customize your characters’ abilities with the right spheres for added flexibility in battle. Happy exploring!
