You can cast Illusion spells without providing Verbal components, and if an Illusion spell you cast has a range of 10+ feet, the range increases by 60 feet.
You also know the Minor Illusion cantrip. If you already know it, you learn a different Wizard cantrip of your choice. The cantrip doesn't count against your number of cantrips known. You can create both a sound and an image with a single casting of Minor Illusion, and you can cast it as a Bonus Action.
