The Cult of Slaanesh (rules)

* The Army General must be a High Sorceress, or a Sorceress if no High Sorceress is present (even if they do not have the highest Leadership in the army).
* The Army General must have the Mark of Slaanesh.
* Daemons cannot join units of Dark Elves or Mortal Chaos.
* Dark Elf characters cannot join units of Mortal Chaos or Daemons. Aspiring Champions cannot join units of Dark Elves or Daemons.
* Dark Elves with the Mark of Slaanesh still have hatred of High Elves. Units or characters with the Mark of Slaanesh and riding Cold Ones are still subject to stupidity.
* Sorceresses with the Mark of Slaanesh must use the Lore of Slaanesh, and gain +1 to cast their spells.
* All rules for Mark of the Dark Gods (pages 46-47 of Hordes of Chaos) apply.
* Dark Elf characters with the Mark of Slaanesh may take any 'Models with Mark of Slaanesh Only' magic items from Hordes of Chaos as part of their Magic Item allowance.
* Any Dark Elf unit that has the Mark of Slaanesh and access to a Magic Standard may choose to take the Rapturous Standard (from Hordes of Chaos) instead of another Magic Standard (although of course only one Rapturous Standard may appear in the army).
* Chaos characters and units may not use Dark Elf magic items.
