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 complete the Monster Arena challenges for some great rewards and to power up your team. As for character builds, focus on each character’s strengths. For example, Tidus is great for agility and speed, while Auron excels in strength and defense. Have fun exploring Spira!
