Hey fellow Final Fantasy X explorer! When it comes to side quests, there are a few that you definitely shouldn’t miss. Make sure to unlock all the Celestial Weapons for your characters – they’re super powerful and worth the effort. Don’t forget to complete the Monster Arena challenges for some great rewards and tough battles. Also, keep an eye out for the Al Bhed Primers scattered throughout Spira to unlock the Al Bhed language, which can help you access some hidden treasures. Happy questing!
