You grasp a creature and pull the air from their lungs. Make a melee spell attack against the target. On a hit, the creature suffers 3d6 necrotic damage. At the start of the creature's next turn, it must succeed on a Constitution saving throw or waste its action gasping for breath.

This spell has no effect other than damage on a creature that does not need to breathe.

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