Hey fellow Final Fantasy X fan! When it comes to side quests, there are some must-dos in the game. Make sure to complete the Monster Arena challenges to unlock powerful items and fight tough bosses. Don’t forget about the Celestial Weapons – they require some effort to obtain, but they’re totally worth it for the stat boosts. Also, keep an eye out for the Al Bhed Primers scattered throughout Spira to unlock the Al Bhed language. And of course, the optional Aeons and Dark Aeons are a fun challenge for those looking to test their skills. Happy questing!
