Make a melee spell attack. On a hit, the target
takes 3d6 necrotic damage, and you regain hit
points equal to half the amount of necrotic
damage dealt. Until the spell ends, you can make
the attack again on each of your turns as an
action. At Higher Levels, the damage increases
by 1d6 for each slot level above 3rd.
