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. Focus on unlocking key abilities like Quick Hit for Tidus and Holy for Yuna early on.

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 the optional Aeons like Yojimbo and Anima.

When building your characters, try to specialize them based on their strengths. For example, turn Tidus into a speedy physical attacker, Yuna into a powerful white mage, and Auron into a tanky powerhouse. And always remember to keep your party balanced for any situation you may encounter in your journey through Spira!
