You create an image that is no larger than a 15-foot cube. The image appears at an unoccupied spot and lasts for the duration. The image is only visual. If anything passes through it, it's revealed to be an illusion.
You can use your action to cause the image to move to any spot in range. As the image changes location, you can alter its appearance so that its movements appear natural for the image.
A creature that uses its action to examine the image can determine that it is an illusion with a successful Investigation check against your spell save DC. If a creature discerns the illusion for what it is, the creature can see through the image.
You can communicate telepathically with any creature you can see within 30 feet of you. You don’t need to share a language with the creature for it to understand your telepathic utterances, but the creature must be able to understand at least one language.
You can read all writing.
