Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, focus on maximizing each character’s strengths. Start by following their natural path to unlock key abilities and stat boosts. Don’t be afraid to branch out to other sections for additional skills.

For side quests, make sure to complete the Monster Arena challenges for valuable rewards and the Celestial Weapons quest for ultimate weapons. Don’t forget to capture fiends for the Monster Arena and unlock the secret Aeons.

When it comes to character builds, experiment with different paths to tailor your party to your playstyle. Tidus excels in agility and speed, Yuna is a powerhouse in magic, and Auron is a heavy hitter with high HP. Mix and match abilities to create a well-rounded team ready for any challenge.

Happy exploring!
