Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, don’t be afraid to experiment with different paths for your characters. Mixing their specialties can make them versatile in battle. For side quests, make sure to complete the monster arena challenges for some great rewards. As for character builds, focus on maximizing each character’s strengths. For example, Tidus can be a speedy physical attacker, while Lulu excels in magical damage. Have fun exploring Spira!
