A corrosive vapor enshrouds a creature you can see within range. It must make a Constitution saving throw. On a failed save, the creature takes 2d10 acid damage and has its AC reduced by 2 for 1 minute or until the creature is immersed in water. On a successful save, the target only takes half the damage.
