Viola's Vampiric Touch

You touch a creature and siphon out its life force to rejuvenate another creature of your choice within a 5 foot range. If there is none within range of you, you can choose to rejuvenate yourself. On a failed Constitution Saving Throw the targeted creature takes 3d6 necrotic damage or half as much on a successful save.

You or whatever creature you target regains half the damage rolled worth of hitpoints.

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