Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, make sure to focus on each character’s strengths. For example, Tidus is great for agility and speed, so prioritize those nodes for him. Don’t be afraid to mix and match different paths to create unique character builds.

For side quests, make sure to complete the Monster Arena challenges for great rewards and tough battles. Also, don’t miss out on the optional Aeons and Celestial Weapons – they can really boost your party’s power.

When building your characters, consider their roles in battle. For example, Auron is a great tank with high HP and strength, while Yuna excels in magic. Experiment with different abilities and see what works best for your playstyle. Happy exploring!
