Mirage Arcane
7th-level Illusion
Casting Time: 10 minutes
Range: Sight
Components: V, S
Duration: 10 days
You make natural terrain in a 1-mile square area look, sound, smell, and even feel like some other sort of natural terrain. The general shape of the land remains the same, however. Open fields or a road could be made to look like 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 rocky ravine like a wide, flat road.
Likewise, you can alter the appearance of structures, or add them where none are present. The illusion can include audible, visual, tactile, and olfactory elements. It can transform clear terrain into difficult terrain, or vice versa. Any piece of the illusory terrain that is moved out of the spell's area disappears immediately.
Creatures with truesight can see through the illusion to the terrain's true form; however, the illusion still remains, and the creature can physically interact with it.
