Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, my tip is to focus on each character’s strengths. For example, Tidus is great for physical attacks, while Lulu excels in magic. Don’t be afraid to mix and match abilities to create a well-rounded party.

For side quests, be sure to tackle the monster arena for some tough battles and great rewards. The Celestial Weapons are also worth the effort, as they can really boost your characters’ power.

When building your characters, think about their roles in battle. For example, you might want to give Yuna more healing abilities, while Auron can focus on dealing heavy damage. Experiment with different paths on the sphere grid to find the best builds for your playstyle. Happy exploring!
