[QUOTE="Jack Simth, post: 4542596, member: 29252"] Once I get to the dungeon's level, I map it out by placing the sensor at five-foot increments in a given direction, and noting what I see on some parchment I purchased for the purpose. I then take a five-foot offset, and run down that row again. I then take another foot-foot offset.... At any given time, I'm specifying the location in an obvious manner - X feet north (or south), Y feet east (or West) of my current position. With five-foot "grid positions", a 400-foot by 400-foot dungeon (assuming a reasonably level floor, but we can account for 3d if we like) takes 6,400 invocations of the item to map out (fully). If it takes a standard action to note nearby walls on my map, then that takes me 12,800 rounds - at ten minutes per round, that's 1,280 minutes, or 21 hours and 20 minutes. One day's, and I have an enormous area covered. If I judge that 10-foot increments are sufficient, that drops to five hours and 20 minutes. If I judge that 20-foot increments are sufficient (in natural blackness with no darkvision, I do get a ten-foot radius, after all), that drops to 1 hour, 20 minutes. Generally, though, I won't really need to know more than one or two rooms in advance. [/QUOTE]
