Hey fellow FFX explorer! When it comes to sphere grid progression, I recommend focusing on each character’s strengths. For example, Tidus is great for speed and agility, so aim to unlock those nodes first. Don’t be afraid to backtrack to grab important abilities or stat boosts.

For side quests, make sure to complete the Monster Arena challenges for awesome rewards. Also, don’t forget to unlock the Celestial Weapons for your party members by completing their respective side quests.

When it comes to character builds, experiment with different paths on the sphere grid to create unique builds for each character. For example, mix magic and physical attacks for a versatile character. And always remember to have a balanced party to tackle any situation.

Happy exploring! See you in Spira!
