Like Key Items, some materials are required to complete Quests. The include materials and key items which are needed for quest completion. After a certain point in the game, the Monado will sometimes show a vision when a material is collected. These materials will be needed for future quests, and are marked with a white exclamation mark on their icon. It is possible to trigger a vision for an item needed in a mutually-exclusive quest. If the party then chooses the alternate quest, the vision never comes to pass and the item will remain marked with the white exclamation mark for the remainder of the game.
