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 speed and agility, so prioritize those nodes on his grid. Don’t be afraid to mix and match different paths to create unique character builds.

As for side quests, make sure to revisit locations and talk to NPCs multiple times to unlock new quests. The Monster Arena is a great place to level up and earn rare items. And don’t forget about the legendary weapons and Aeons – they’re worth the effort!

When it comes to character builds, experiment with different abilities and spells to see what works best for your playstyle. Mixing and matching different spheres can lead to powerful combinations. And always remember to customize your equipment to enhance your character’s strengths even further.

Happy exploring in Spira!
