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, so prioritize upgrading his strength nodes. Don’t forget to mix in some utility skills like steal and use.

For side quests, be sure to tackle the Monster Arena for awesome rewards and tough battles. Also, don’t miss out on the Celestial Weapons quests for some of the best gear in the game. And of course, the infamous Chocobo Racing for those sweet rewards.

When it comes to character builds, experiment with different paths on the sphere grid to customize your party. Mixing magic and physical attacks can be a game-changer. And don’t forget to use the Expert Sphere Grid for even more customization options. Happy exploring!
