The creation of Nightmare Dolls is a risky practice in Commorragh, as the Dark Eldar view those who use psychic powers as amusing playthings. These vile toys ooze an aura of pain, and can place their owner into a feverish delirium whereby they are often granted visions of the future.
A Dark Eldar model equipped with a Nightmare Doll may force his opponent to re-roll the dice when ascertaining who may choose table edge or quarter. If the Dark Eldar player opts to do this, the model with the Nightmare Doll takes a Strength 3 hit at the beginning of the first Dark Eldar turn with no saves of any kind allowed.
