In the game, there are optional things in which you can partake in. You can find rare things if you do side quests. You can't take part in some of these events, however, until you have come to a certain point in the game. But when you can participate in these events, it really doesn't matter when you do it. You should take the challenge of a side quest As Soon As Possible since sometimes it can dramatically increase your party's status. On my side quest sites, I will list when it is available, how hard or easy it is, how good the reward is, when it is not available, draw points you find while doing this, Save points, and what magazine you find there. Of course I will list a walkthrough on how to complete the side quest. Have fun! These are a bit hard, but they can be loads of fun if you have an adventurous spirit and love a good challenge.
