Daemonic Possession
(Rule)Description: A daemonic model can possess any other model in the Chaos Space Marine army which bears a Mark of Chaos, with the exception that Greater Daemons can only enter play by possessing a Chaos Champion, Chaos SOrcerer, or Chaos Lord that bears their Mark. Remove the possessed model and replace it with the daemon at the end of the psychic phase, at the asme time or normal summoning. Models that are in close combat may be possessed.
The model that has been possessed is killed by this transformation and treated as a casualty for VP purposes, but do not count for taking a Break test. Regular daemons must still enter in units of 3.
