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 aim to unlock those nodes first. Don’t be afraid to send characters down different paths to learn new abilities and gain stat boosts.

For side quests, definitely try to complete the Monster Arena challenges for some awesome rewards. And don’t forget about the celestial weapons – they’re a bit tricky to obtain, but totally worth it for the power boost they provide.

When it comes to character builds, experiment with mixing different abilities to create well-rounded characters. For example, giving Yuna some black magic spells can make her a versatile healer and damage dealer. And don’t neglect HP and MP nodes – having a healthy pool of both can make a big difference in tough battles.

Happy exploring! Feel free to share your own tips too.
