Your weapon or body briefly blackens with rot as you strike your target. You deal an extra 2d6 necrotic damage to the target and disintegrate its flesh. The target must make a Constitution saving throw. On a failed save, it has disadvantage on attack rolls, ability checks, and saving throws made with Strength for the next minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on a success.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the extra damage increases by 1d6 for each slot level above 2nd.
