An area of false vision encompasses all creatures within 20 feet of you. You and each creature in the area that you choose to affect take on the appearance of a harmless creature or object, chosen by you. Each image is identical, and only appearance is affected. Sound, movement, or physical inspection can reveal the ruse. A creature that uses its action to study the image visually can determine that it is an illusion with a successful Intelligence (Investigation) check against your spell save DC. If a creature discerns the illusion for what it is, that creature sees through the image.
