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 upgrading their strengths first before branching out to other abilities.

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 quests for some of the best gear in the game. And if you’re up for a challenge, try capturing all the monsters in the Calm Lands!

As for character builds, think about each character’s strengths and roles in battle. For example, Tidus is great for agility and speed, so you might want to focus on enhancing his physical attacks. Yuna, on the other hand, excels in magic, so prioritize upgrading her magical abilities on the grid.

Happy exploring! Feel free to ask if you need more tips or have any questions.
