Hey fellow Final Fantasy X explorer! When it comes to side quests, there are some key ones you shouldn’t miss. Make sure to complete the Monster Arena challenges for some great rewards and to unlock some powerful enemies. Don’t forget about the Celestial Weapons quests for each character, as they are essential for end-game content. And of course, the Al Bhed Primers scattered throughout Spira are worth collecting for some cool lore and a language bonus. Happy questing!
