You create an image from an object, creature, or other visible phenomenon no larger than a 15-foot cube. The image appears at a location within casting distance that you can see and persists for the duration of the spell. The image is purely visual; it is not perceived by hearing, smell, or other senses.
Silent Image 5e
Level: 1st
Classes: Wizard, Bard, Sorcerer
Casting Time: 1 Action
Range: 60 feet
Components: V, S, M
Duration: Concentration, up to 10 minutes
You can use movement to move the image to another location within casting distance. When the image changes position, you can change the image’s appearance to make it move more naturally. For example, if you create an image of a creature and move it, you can change the image to make it appear as if it is walking.
Since the image cannot be touched, any physical interaction with the image will reveal the nature of the illusion. When a creature investigates the image with its actions, it can make an Intelligence (Investigation) check against the spell immunity DC to determine whether to see through the illusion. A creature that recognizes an illusion can see through the image, and it appears to the creature to see what is behind it through the image.
