Mordenkainen's Lost Notebook
3-level Necromancy
Choose a target you can see within range. That creature must succeed on a Constitution saving throw or suffer a blistering rash accompanied by a maddening itch. The creature is poisoned for the duration. In addition, if the creature uses its movement or takes any action other than a bonus action, it takes 1d8 psychic damage. In addition, the target makes Strength and Dexterity checks and saving throws with disadvantage. If a subject under the effects of prickling torment is targeted by fever dream, the spells interact to create a cumulative effect. See the fever dream spell for details.
