Canvas Cover

You paint a highly realistic, static mural over a flat surface, such as a wall, floor, or door. The illusion must fit within a 10-foot-by-10-foot square.

The painted image is perfectly photorealistic and blends seamlessly with the surrounding environment. You can use this to make a door look like a blank stone wall, make a pit look like a solid floor, or paint a fake tunnel. A creature that carefully examines the mural can make an Intelligence (Investigation) check against your spell save DC to realize it is an illusion. Physical interaction with the mural reveals it to be an illusion, as things simply pass through the painted surface.
