Hey fellow FFX explorer! When it comes to sphere grid progression, don’t be afraid to mix and match different paths for your characters to maximize their strengths. Focus on key abilities first to make battles easier. For side quests, be sure to complete the Monster Arena challenges for rare items and AP. Character builds depend on your playstyle, but consider specializing each character to excel in a specific role like tank, healer, or magic user. Experiment and have fun customizing your party!
