Key Items are unique, non-consumable items that are essential for story progression, unlocking new areas, or initiating side quests. These items cannot be sold or discarded. Examples include the Sorcerer's Ring, which is used for puzzles and activating switches, various elemental pacts, and specific quest-related objects. Always pay attention to the descriptions of key items, as they often provide hints on where to go next or how to solve a particular puzzle. Your inventory will automatically manage these items, and they will typically be used automatically when their purpose is met. Collecting all key items is a natural part of completing the main story and most side quests.
