Dead Man's Grip

You cause a tendril of necromantic energy to grip itself around the target's very soul.

Choose a creature within range - the target must make a Wisdom saving throw. On a failure, the target takes 8d8 necrotic damage, plus 1d8 necrotic damage for every 10 hit points the creature is missing from its current hit point maximum.

If the target is reduced to 0 hit points from this spell, its soul is destroyed - only a Wish spell can bring a creature that was killed in this way back to life.
