Vitality Exchange

You rip the life force from all creatures withing a 20ft cone in-front of you that makes a CON saving throw and channel the essence to another creature within 30ft of you that isn't you, on a failed save they take 3d12 necrotic damage and the receiver gains 3d4+ spell casting modifier hit points, on a pass they take half damage and you cannot heal anyone.

up-casting increases the dice on both damage and healing by one die as well as increase the range of the cone by 5ft.
