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’s a good idea to focus on each character’s strengths, but also consider branching out to learn new abilities.

For side quests, make sure to complete the Monster Arena challenges for some awesome rewards and tough battles. Don’t forget to unlock the Celestial Weapons for your party members by completing their respective mini-quests. They’re super powerful and worth the effort!

As for character builds, try to specialize each character based on their role in battle. For example, Tidus can be a speedy attacker, Yuna a powerful healer, and Auron a tanky damage dealer. Mix and match abilities from different paths to create the ultimate team. Happy exploring!
