The next time you hit a target with a ranged weapon attack during the spell’s duration, the projectile sizzles and sprays a gout of acid on collision. The attack deals an additional 3d6 acid damage and the target must succeed on a Constitution saving throw or have their AC reduced by 1 for 1 minute. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
