You make the 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.
Regardless of whether hostile creatures believe the illusion, they are effectively slowed within the area of effect. Friendly creatures are treated as having cover, which gives them a concealment of 50%.
Only one hallucinatory terrain may be active per area.
