Key Items and Quest Items are non-consumable items that are essential for progressing through the main story or completing side quests. These items are automatically used when their conditions are met and cannot be sold or discarded. They often represent plot devices, puzzle solutions, or proof of quest completion.
- Key Items: Examples include 'Movie Tickets' that grant access to new labyrinths, 'Projector Parts' needed to repair the Central Cinema, or 'Special Keys' that unlock specific doors within dungeons.
- Quest Items: These are specific items requested by NPCs for side quests, such as 'Lost Wallets', 'Data Fragments', or 'Rare Monster Drops'. Once a quest item is obtained, it will remain in your inventory until you turn in the quest.
Always pay attention to the descriptions of Key Items and Quest Items, as they often provide clues on where to go next or what to do. Your inventory will automatically manage these items, so you don't need to worry about accidentally using or losing them. Collecting all Key Items and completing all Quest Item-related tasks is necessary for 100% completion.
