Let’s play with some of the spell rules a bit…. How about one where you gamble!

You point at a creature in range as the forces of life and death coalesces around the hapless creature. That creature may elect to make a Charisma saving throw. If the creature does not, that creature takes 2d10 necrotic damage. If the creature does make the roll and succeeds, that creatures heals 2d10 damage. If the creature makes the roll and fails, that creature is dealt 4d10 necrotic damage.
