Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, don’t be afraid to branch out and experiment with different paths for your characters. Mixing both their default paths and branching out to learn new abilities can make your party more versatile in battles.

For side quests, make sure to complete the monster arena challenges for some great rewards and tough battles. Also, don’t forget about the celestial weapons and aeons, they can be a game-changer in tough boss fights.

When it comes to character builds, focus on maximizing each character’s strengths. For example, Tidus is great for speed and agility, Yuna for magic, and Auron for raw power. But don’t be afraid to mix it up and create unique builds that suit your playstyle. Happy exploring!
