Major Illusion

Target. A spot within range.

Effect. You create the image of an object, a creature, or some other visible phenomenon that is no larger than a 15-foot cube. The image is purely visible; it isn't accompanied by sound, smell, or other sensory effects. Physical interaction with the image reveals it to be an illusion, because things can pass through it. A creature that uses its Action to examine the image 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, the creature can see through the image.

Special. As long as you are within range of the illusion, you can use your Action to cause the image to move to any other spot within range. As the image changes location, you can alter its appearance so that its movements appear natural for the image. For example, if you create an image of a creature and move it, you can alter the image so that it appears to be walking.

At Higher Levels. When you cast this spell using a spell slot of 2nd or 3rd level, the duration is concentration up to 1 hour. If you cast this spell using a spell slot of 4th or 5th level, the duration is concentration up to 8 hours. If you cast this spell using a spell slot of 6th level or higher, the spell lasts until dispelled, without requiring concentration. Casting this spell at 3rd level or higher increases the size of the illusion to a 20-foot cube, and the image can seem completely real, including sounds, smells, and temperature appropriate to what is being depicted, though it cannot cause damage or otherwise harm environments, objects, or creatures. When you use your Action to manipulate the image, you can cause it to make different sounds at different times, even making it carry on a conversation.
