Cleansing Blindness

You hurl a small piece of soap at a target within range. The soap expands into a frothy mass and the target must make a Dexterity saving throw. On a failed save, the target takes 3d8 acid damage and is blinded until the end of its next turn. On a successful save, the spell has no effect.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8, for each slot level above 1st.
