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 maximize their potential. Make sure to focus on each character’s strengths – for example, Tidus is great for speed and agility, while Auron excels in strength and defense.

For side quests, be sure to complete the Monster Arena challenges for some great rewards and tough battles. Don’t forget about the celestial weapons and aeons – they can really make a difference in those challenging boss fights.

When it comes to character builds, think about where you want each character to specialize. Whether it’s turning Lulu into a powerful black mage or Kimahri into a versatile all-rounder, there are plenty of options to customize your party to suit your playstyle. Keep exploring and experimenting, and most importantly, have fun on your journey in Spira!
