Enervating Grasp

You attempt to grasp a creature and temporarily drain it of its vigor. Make a melee spell attack against the target. On a hit, the target takes 1d6 necrotic damage, and it has disadvantage on the first ability check or attack roll it makes before the end of its next turn. This spell has no effect on undead or constructs.

This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
