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 and match different paths on the grid to create unique character builds. 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 capturing all the monsters in the Calm Lands. Happy exploring!
