Hey fellow Final Fantasy X explorer! When it comes to side quests, there are a few must-dos in the game. Don’t miss out on the Monster Arena where you can battle different fiends for rewards and unlock powerful enemies. The Celestial Weapons quests are also essential for maximizing your character’s potential. Make sure to complete the butterfly hunt in Macalania Woods for some sweet rewards. Lastly, don’t forget about the Al Bhed Primers scattered throughout Spira – collecting them all unlocks a special scene at the end of the game. Happy questing!
