[Question] Combat Efficient Psykers?

In the Inheritance Cycle universe, advanced librarians are inducted into methods of crazy efficient murder. Spells for pinching off a specific artery, severing certain nerves, using less psychic energy than wiggling their finger, and allowing them to slaughter entire armies not under the aegis of an enemy psyker.

Is there any such lore in 30-40k of similar techniques? We can see plenty events of a alpha psykers lifting a hive spire, or flying with angel wings. But severing the spinal chords of an enemy platoon?
