Choose a humanoid you can see within range. The target must succeed on a Dexterity saving throw or be paralyzed for the duration of the spell. At the end of each of it’s turns, the target must make a Constitution saving throw or take 4d4 Necrotic damage. On a success, the spell ends for the target. When a creature is damaged by this spell, a creature of your choice within 60 ft. of the target regains hit points equal to half the damage dealt rounded down.
