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 agility and speed, so prioritize those nodes for him.

Don’t forget to unlock key abilities like Quick Hit and Ultima for powerful attacks. As for side quests, make sure to complete the Monster Arena challenges for rare items and AP. The Celestial Weapons are a must-have for endgame content, so take the time to upgrade them through various side quests.

Experiment with different character builds to find what works best for your playstyle. Whether you prefer physical attacks, magic, or support roles, there are endless possibilities on the sphere grid. Happy exploring!
