Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, I recommend focusing 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 on the grid to create unique character builds.

As for side quests, make sure to complete the Monster Arena challenges for some awesome rewards and tough battles. Also, don’t miss out on capturing all the monsters for the Calm Lands Arena. And of course, the legendary weapons and Aeons quests are a must for any completionist!

When building your characters, think about their roles in battle. For instance, Auron makes a great tank with high HP and strength, while Yuna is best suited for healing and support magic. Experiment with different abilities and find what works best for your playstyle.

Happy exploring and may Yevon guide your journey in Spira!
