Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, don’t be afraid to mix things up. Experiment with different paths for your characters to unlock new abilities and stats. For side quests, make sure to visit all the temples to obtain legendary weapons and don’t forget to participate in blitzball for some fun diversion. As for character builds, focus on each character’s strengths. For example, Tidus is great for agility and speed, while Lulu excels in magic. Have fun exploring Spira!
