Hey fellow Final Fantasy X explorer! When it comes to side quests, there are a few you definitely shouldn’t miss. Make sure to complete the Monster Arena challenges for some great rewards and tough battles. The Celestial Weapons side quest is also a must-do for powerful gear. Don’t forget about the optional Aeons like Yojimbo and the Magus Sisters, they can be a game-changer in tough battles. Lastly, the Al Bhed Primers scattered throughout Spira are worth collecting for some cool lore insights. Happy questing!
