You make 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.

Material Component: A stone, a twig, and a bit of green plant.
