You wrap a creature, object, or location that you can see within range in an outward-facing illusion. If the target is an unwilling creature or an object being carried or worn by one, the creature must make a Charisma saving throw. On a successful saving throw, the spell fails and the creature becomes aware that magic was cast on it.

Creatures that are too close to the illusion are unable to perceive it. You decide what the illusion looks and sounds like, as well as the minimum range away from the target at which the illusion can be perceived, which can't be shorter than 1 foot or longer than 15 feet. The illusion can create sound and can be as large as can fit inside the chosen range. It stays centered on the target even if the target moves.

The illusion can trick the senses of sight and hearing, but not touch, smell, or other senses. Physical interaction with the illusion reveals it to be false, because things can pass through it. A creature that uses its action to examine the illusion can determine that it is an illusion with a successful Intelligence (Investigation) check against your spell save DC.

As long as you are within range of the illusion, you can use your action to cause the image to alter its appearance and sound. The illusion lasts until the spell ends, at which point it vanishes.
