Vampiric Transfer

With a touch of your hand you can siphon life force from a creature to heal another's wounds.
Make a melee spell attack against a creature within your reach. On a hit, the target takes 6d8 necrotic damage, and a target of your choice within 30ft regain hit points equal to half the amount of necrotic damage dealt.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 2d8 for each slot level above 4th.
