Acid Mist

You conjure a misty puff of acid on ground that you can see within range. Until the spell ends, the puff of acid fills a 5-foot cube. Any creature in the puff's space when you cast the spell must succeed on a Dexterity saving throw or take 1d6 acid damage. A creature must also make the saving throw when it moves into the puff's space for the first time on a turn or ends its turn there.

The spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
