Hey fellow Final Fantasy X explorer! When it comes to side quests, there are a few must-dos in the game. Make sure to complete the Monster Arena challenges for some awesome rewards and tough battles. Don’t forget to collect all the Al Bhed Primers for a special surprise later on. And of course, the Celestial Weapons quests are a must for those ultimate weapons. Happy hunting and may Yevon guide your way on your side quest adventures!
