Minor Illusion

Level: Cantrip

Casting time: 1 Action

Range: 30 feet

Components: S, M

Duration: 1 minute

When casting this 5e spell, You create a sound or an image of an object within the casting distance and maintain it until the spell duration ends. You can also dismiss the illusion with an action, or cast the spell again to terminate the illusion.

If you create an image of an object (such as a chair, muddy footprints, a small box, etc.), the size of the object should not be larger than a cube with a side of 5 feet.

The image has no sound, light, taste, or any other sensory effects. Since the image can be penetrated by any object, the physical interaction with it will reveal the essence of its illusion.

If you create a sound, its volume can be a low whisper or a loud scream. It can be the voice of you or anyone else, or the roar of a lion, a drum sound, and any other sound you specify.

The sound will not diminish for the duration, or you can create several scattered sounds in different time periods before the spell ends.

When a creature uses its actions to investigate the sound or image, it must make an Intelligence (Investigation) check against the spell’s save DC. If the check succeeds, it is judged to be an illusion. The illusion will appear blurred in front of the creatures that see through it.
