Hey fellow Final Fantasy X adventurers! When it comes to side quests, make sure to prioritize the Monster Arena challenges. Not only do these battles provide great rewards, but they also help you capture fiends for the Arena. Don’t forget to visit the Cactuar Village and complete the Cactuar side quest for some awesome AP and HP spheres. And of course, don’t miss out on the celestial weapons quests for some of the most powerful gear in the game! Happy questing!
