The character makes natural terrain look, sound, and smell
like some other sort of natural terrain. Thus, open fields or a
road can be made to resemble a swamp, hill, crevasse, or some
other difficult or impassable terrain. A pond can be made to seem
like a grassy meadow, a precipice like a gentle slope, or a
rock-strewn gully like a wide and smooth road. Structures,
equipment, and creatures within the area are not hidden or
changed in appearance.
