Transfusion

You point your fingertips with hands shaped like claws towards your target and make a ranged spell attack. The skin on your fingertips rips open slightly and reveals your flesh underneath.
On a hit, life force flows through the air from your target towards your fingertips, dealing 6d6 necrotic damage to the target and healing you for half the damage dealt.
This spell has no effect on undead or constructs.

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.
