Possessing Models
(Rule)Description: May possess a model with expenditure of summoning points. A daemon model can possess any other model in the Chaos Space Marine army which bears its Mark of Chaos, with the exception that Greater Daemons can only enter play by possessing a Chaos Champion, Chaos Sorcerer or Chos Lord that bears their mark.
Remove the model that has been possessed and replace it with the daemon model at the end of the psychic phase. Models that are in close combat may be possessed as well.
The model is treated as killed for all victory point purposes. Models that die this way do not count as casualties for Break test.
Daemons that are not Greater Daemons must still enter play in units of 3 or more.
