Ventrical Implosion

You reach out and shred a creature’s veins. The target must make a Constitution Saving Throw. On a failed save, the target takes 10d12 necrotic damage and is bleeding, taking half as much damage again each turn until magically healed or passing a Medicine Check equal to your Spell Save DC. On a successful save, the target takes half as much damage and is not bleeding.

At higher levels: When you cast this spell as a 9th level spell, the damage increases by an additional 4d12.
