Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, don’t be afraid to branch out and experiment with different paths for your characters. It can be beneficial to mix both standard and expert sphere grids for a well-rounded team.

For side quests, be sure to complete the monster arena challenges for some great rewards and tough battles. Don’t forget about the celestial weapons and aeons as well. They can make a huge difference in your journey.

As for character builds, tailor your sphere grid paths to each character’s strengths. For example, focus on agility and luck for Tidus to make him a speedy powerhouse, while emphasizing magic for Lulu to maximize her spell-casting abilities. And don’t underestimate the power of mixing and matching abilities from different paths for a truly unique build. Happy exploring!
