Demonic Drain

An Arcane sigil appear beneath 2 Creatures you can see within range, one friendly and one enemy. The enemy needs to make a Constitution Saving Throw against your Spell Save DC. Taking 6d6 necrotic damage or half as much on a success. As grasping demonic arms/hands, Tentacles, or Vines (depending patron) shoot from the sigil into the target then back down into the sigil. The friendly creature then receives half of that total in healing as spectral beings float upwards from their sigil into their body. Spectral Beings take the form of the casters choosing.

When casting at Higher levels add an additional 1d6 per level above 4th level spell slot.
