Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, don’t be afraid to mix things up. Experiment with different paths for your characters to unlock new abilities and stats. Remember to prioritize key abilities like Quick Hit for Tidus and Doublecast for Yuna.

For side quests, make sure to complete the Monster Arena challenges for some great rewards and tough battles. Also, don’t miss out on the Celestial Weapons quests for those ultimate weapons.

As for character builds, focus on maximizing each character’s strengths. For example, boost Auron’s strength and HP to make him a powerhouse in battles, while enhancing Lulu’s magic skills for devastating spells. And remember, customization is key in creating a well-rounded party! Happy exploring!
