Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, make sure to focus on developing each character’s strengths. Don’t be afraid to mix and match different paths to create a well-rounded team.

For side quests, don’t miss out on the Monster Arena challenges and the Celestial Weapons quests. They offer great rewards and help you power up your characters. Also, make sure to keep an eye out for Al Bhed Primers to unlock additional abilities in the grid.

As for character builds, consider specializing each character based on their unique abilities. For example, Tidus excels in agility and speed, so focus on enhancing those traits. Auron is a powerhouse, so boost his strength and defense. Experiment with different strategies to find what works best for your playstyle. Happy exploring!
