Exploration Quests

Exploration quests sometimes appear in stages when you clear all of their quests.

In these quests, you are free to walk around and explore a map.
Because exploration quests do not affect your progress in the main story, you are free to decide whether or not to embark on them.

Some stages do not have exploration quests.

In order to open a locked treasure chest in an exploration quest, you will need to put a magic key in your item set before you depart for the quest.
