You fabricate the image of a passageway such as a doorway, curtain, arch, or tunnel in a space you can see within range. The image can be up to 20 fet wide, 20 feet tall, and 5 feet thick. Creatures who see the illusion when it appears automatically know it is an illusion.

A creature can determine the passage is an illusion with a successful Intelligence (Investigation) check against your spell save DC. If a creature knows the passageway is an illusion, it can see through the image.

At Higher Levels. When you cast this spell with a spell slot of 5th level or higher, the duration increases to 24 hours.
