Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, don’t be afraid to mix and match different paths for your characters to unlock a variety of abilities. Focus on upgrading key stats like HP, strength, and magic early on to make battles easier.

For side quests, be sure to complete the monster arena challenges for valuable rewards and to unlock powerful aeons. Don’t forget to hunt down all the celestial weapons for your party members – they can be a game-changer in tough battles.

When it comes to character builds, tailor each character to their strengths. For example, focus on magic for Lulu, agility for Tidus, and defense for Auron. Experiment with different abilities and see what works best for your playstyle. Happy exploring!
