Draining Bond

Select a Creature. You create a red energy bond between you an the selected target. The victim's hit points receive 3d6 necrotic damage for 1 minute at the end of your turn and you gain half of the damage taken back as hit points.

As the creature moves out of range of the spell, the bond is torn off. The bond automatically regenerates for the remainder of the concentration as you move within the required range.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
