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. It can be beneficial to focus on each character’s strengths, but also consider branching out to learn new abilities and maximize their potential.

For side quests, be sure to complete the Monster Arena challenges for some epic battles and rewards. Don’t forget about the Celestial Weapons either – each character has a powerful weapon waiting to be obtained through various mini-quests.

When it comes to character builds, think about the role you want each character to play in your party. Whether it’s a tank, healer, or damage dealer, tailor their sphere grid progression and abilities to complement their role. And don’t overlook the importance of customizing your aeons as well to make them even more formidable in battle. Happy exploring!
