You make natural terrain domain in a 150-foot cube in range look, sound, and smell like the terrain you imagined. 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. Manufactured structures, equipment, and creatures within the area aren't changed in appearance.
This spell lasts as long as the spellcaster holds concentration, is not unconcious or dead, or until the battle ends. Any friendly creature in the terrain gets resistance to non-magical damage, and which ever terrain is made, the battle enviornment and rules of that terrain now apply. For a hostile creature to escape the terrain expansion they must succeed on a DC(12+ Deception Modifier of Caster) throw on their turn.
