Hey there fellow Final Fantasy X explorer! When it comes to sphere grid progression, my tip is to focus on each character’s strengths. For example, Tidus is great with agility and speed, so prioritize those nodes for him.

Don’t forget to unlock key abilities like Quick Hit and Ultima for powerful attacks.

For side quests, don’t miss out on the Celestial Weapons and Aeons. They can make a huge difference in tough battles.

Experiment with different character builds to find what works best for your playstyle. Whether you prefer a tanky Auron or a magic-focused Lulu, there are endless possibilities to customize your party. Happy exploring!
