Hey fellow Final Fantasy X explorer! When it comes to side quests, make sure to tackle the Monster Arena challenges for some epic battles and rewards. Don’t forget to hunt down all the Al Bhed Primers for a cool language bonus. The Celestial Weapons quests are a must for ultimate power, but be prepared for some tough trials. And of course, the elusive and powerful Aeons like Yojimbo and Anima are worth seeking out. Happy questing!
