Hey fellow Final Fantasy X explorer! When it comes to side quests, there are a few key ones you don’t want to miss. Make sure to complete the Monster Arena challenges for some epic battles and rewards. Don’t forget about the Celestial Weapons quests for each character – they are super powerful when fully upgraded. And if you’re up for a challenge, the Dark Aeons and Penance await you post-game for the ultimate test of strength. Happy questing!
