Hey fellow Final Fantasy X explorer! When progressing through the sphere grid, focus on upgrading your characters’ main stats first before branching out. Make sure to strategically choose the path that benefits each character’s unique strengths.

For side quests, don’t miss out on the Celestial Weapons which are powerful weapons for each character. Also, completing the monster arena and unlocking the legendary aeons are great challenges to undertake.

In terms of character builds, experiment with different abilities and skills to find what works best for you. Whether you prefer a magic-heavy Black Mage Yuna or a physical powerhouse Tidus, there are endless possibilities to customize your party. Happy exploring!
