Hey fellow Final Fantasy X 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 be afraid to mix things up and have characters learn abilities outside their typical roles to make your party more versatile.

For side quests, make sure to complete the Monster Arena challenges for valuable rewards and tough battles. Also, don’t forget about the Celestial Weapons and Aeons quests for some of the best gear in the game.

Lastly, experiment with different character builds to find what works best for your playstyle. Whether you prefer heavy hitters or support characters, there’s a lot of room for customization in the sphere grid. Happy exploring!
