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 speed and agility, so prioritize those nodes for him.

For side quests, don’t forget to complete the Monster Arena challenges for some sweet rewards and tough battles. Also, be sure to unlock the legendary weapons by completing the celestial weapon side quests for each character.

As for character builds, experiment with mixing different abilities from other paths on the sphere grid to create a well-rounded party. Don’t be afraid to try out different strategies to see what works best for your playstyle. Happy exploring!
