Hey fellow Final Fantasy X explorer! When it comes to side quests, don’t miss out on the Celestial Weapons quests for each character. They are powerful and totally worth the effort. Also, make sure to complete the Monster Arena challenges for some great rewards and tough battles. Don’t forget about the Al Bhed Primers scattered throughout Spira – collecting them all unlocks some cool secrets. And lastly, keep an eye out for the optional Aeons and Dark Aeons for some epic battles and ultimate rewards. Happy questing!
