You create a sound or an image of an object within range that lasts for the
Duration. The
Illusion also ends if you dismiss it as an
Action or cast this spell again.
If you create a sound, its volume can range from a
Whisper to a scream. It can be your voice, someone else's voice, a lion's roar, a beating of drums, or any other sound you choose. The sound continues unabated throughout the
Duration, or you can make discrete
Sounds at different times before the spell ends.
If you create an image of an object - such as a chair, muddy footprints, or a small chest - it must be no larger than a 5-foot cube. The image can't create sound, light, smell, or any other sensory
Effect. Physical interaction with the image reveals it to be an
Illusion, because things can pass through it.
If a creature uses its
Action to examine the sound or image, the creature 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
Illusion becomes faint to the creature.
