Unrelenting Cruelty

You touch a willing or incapacitated sapient creature within range.  If the creature does not have a human or semi-human physiology, is not organic, or has a CR over 2, the spell fails.  The avenue of your torture rises from your hand and flies onto/into the creature.  The nails will embed themselves in the creature's torso, the leech will attach to the back of the creature's neck, and the wire will wrap itself around the creature's neck like a collar.  The instruments are painless to the creature unless they pierce a bone or vital organ.  As a bonus action, you can use the attached instrument to cause unbearable pain to the creature.  The type and location of pain varies with the instrument.  The nails will shift and tear the flesh, the leech will bite into the creature's spinal cord, and the wire will tighten and briefly strangle the creature.  As a bonus action, you can cause the instrument to heat up to cause pain.  The heat lasts until you end it as a bonus action.  While the heat lasts, the creature takes 1d4 fire damage per hour, which cannot be healed until the heat is removed.  All Charisma checks made against the creature have advantage for as long as the creature is in pain, and for an hour afterward.  The creature has disadvantage on all Charisma and Intelligence checks and saves while in pain.  As an action, you can cause mind-shattering agony in the creature.  The creature must make a DC 12 Constitution save or immediately drop to 0 hit points.  If you do this, the spell ends.
