You've gotten your hands dirty in the field before, and you know how to source what you need in a pinch. Make a spell attack roll against an enemy within touch range of you, and upon doing so deal 5d4 of necrotic damage to them. As a bonus action, you may apply that damage dealt to an ally within touch range, split between health and temporary hit points.

Using a Higher-Level Spell Slot. The damage increases by 2d4 for each spell slot level above 3.
