Acid Wind

You produce a breeze full of stinging acid droplets. Each creature in a 15-foot cube originating from you must make a Constitution saving throw. On a failed save, a creature takes 2d4 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.

Overcharge Tech. When you cast this power using a tech slot of 2nd level or higher, the damage increases by 1d4 for each slot level above 1st.
