Map of the Master Strategist

This black leather wrapped vellum map can be rolled and unrolled with the help of a single silver clasp. The map itself appears blank, save for an intricate compass rose in the lower left hand corner.
Benefit: When you attune to the Map of the Master Strategist, you must remain attuned to it until the end of the [Scene]. Once attuned, the previously blank map will draw a map of a 250 ft square centered on your current location and elevation, including topographical details of open terrain (such as open plains or a forest) and inner architectural details of closed terrain (such as inside a building or dungeon) that are not intentionally hidden.

By spending an entire [Round] without using any actions or making attacks of opportunity, the map can be commanded to update, magically erasing itself and redrawing your new location. The map does not automatically remain accurate.
