Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, don’t be afraid to mix things up and experiment with different paths for your characters. Try not to spread your characters too thin in the beginning, focus on a specific role for each one. For side quests, definitely don’t miss out on the Monster Arena and the Celestial Weapons quests for some awesome rewards. As for character builds, consider customizing your sphere grid to maximize each character’s strengths – whether it’s physical attacks, magic, or support abilities. Happy exploring!
