Vicious Venom

A line of caustic acid 30 feet long and 5 feet wide emanates from you in a direction you choose. Each creature in the line must make a Constitution saving throw. A creature takes 2d10 acid damage and is blinded until the end of its next turn on a failed save, or half as much damage and is not blinded on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for each slot level above 2nd.
