Veil of Mist

You create a 30-foot cube of water mist centered on a point within range. It lasts for the duration, until a wind of moderate or greater speed (at least 10 miles per hour), or a large fire disperses it. 

Once created you can shape and move the mist as you choose within range.  Visibility inside the area is lightly obscured*.

This spell cannot be cast underwater. 

* In a lightly obscured area, creatures have disadvantage on Wisdom (Perception) checks that rely on sight.
