Effects

By means of this spell, the wizard causes an illusion that hides the actual terrain within the area of effect. Thus, open fields or a road can be made to look like a swamp, hill, crevasse, or some other difficult or impassable terrain. A pond can be made to look like a grassy meadow, a precipice like a gentle slope, or a rock-strewn gully like a wide and smooth road. The hallucinatory terrain persists until a dispel magic spell is cast upon the area or until the duration expires. Individual creatures may see through the illusion, but the illusion persists, affecting others who observe the scene. If the illusion involves only a subtle change, such as causing an open wood to appear thick and dark, or increasing the slope of a hill, the effect may be unnoticed even by those in the midst of it. If the change is extreme (for example, a grassy plain covering a seething field of volcanic mudpots), the illusion will no doubt be noticed the instant one person falls prey to it. Each level of experience expands the dimensions of the cubic area affected by 10 yards; for example, a 12th-level caster affects an area 120 yds. x 120 yds. x 120 yds.
