Touch of Death

A necrotic miasma surrounds your hand, and saps the life force of the creature you grasp with it. Make a melee spell attack against the target. On a hit, the target takes 1d8 Necrotic damage, and it can't take regain health by any means until the start of the casters next turn.

The spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
