Acid Wind

You call forth a breeze full of stinging acid droplets from your outstretched hand. Each creature in a 15-foot cube originating from you must make a Constitution saving throw. On a failed save, a creature takes 2d6 acid damage and is blinded until the end of your next turn. On a successful save, the creature takes half as much damage and isn't blinded

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
