Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, focus on unlocking character’s key abilities first, then branch out to secondary paths for more versatility. Don’t be afraid to backtrack to grab important nodes. For side quests, be sure to complete all of the monster capturing in the Calm Lands for great rewards and to unlock the legendary weapons. When it comes to character builds, experiment with different paths to suit your playstyle. Tidus excels in speed and agility, Auron in strength, and Yuna in magic. Enjoy your journey through Spira!
