When you choose this school at 2nd level, you learn the minor illusion cantrip. If you already know this cantrip, you learn a different wizard cantrip of your choice. The cantrip doesn't count against your number of cantrips known.
When you cast minor illusion, you can create both a sound and an image with a single casting of the spell.
