Chest of Drawers (Magic Chest)

This chest is of high quality and fine construction. Upon command, it summons 100 tiny, sprite-like creatures who arrive within it. They vanish if the chest is opened and thus cannot be seen except by clairvoyance or other magical scrying. If a gem valued at 1,000 gp or more is left in the chest along with a piece of parchment, the tiny creatures draw a map. They bring their own drawing tools, and, if left undisturbed for one hour, they draw a map of the horizontal area within 360' of the chest. The sprites then take the gem, and depart. The chest can now be opened and the map taken. The map is accurate and complete, and includes secret, magical, and concealed doors, pit traps, walls, and so forth. No creatures or treasures are noted, and magical doors, walls, and hidden passages, are indicated by an “M.” If, when they arrive, the creatures find no gem, they curse the one who summoned them and immediately depart. The curse may be of any standard type, but can only be removed by a caster of 15th-level or higher. The creatures may be summoned once per day.
