Daemonic Corruption Any Objective Markers controlled by units from this Detachment at the end of your turn count as being under your control for the rest of the game, even inf you have no units within 3" of them. A unit can only corrupt a single Objective Marker in this manner at the end of each of your turns. This effect lasts until an enemy scoring unit cleanses the objective by controlling it.
Patronage of the Dark Gods Psykers from this Detachment can choose to generate all of their psychic powers from the Discipline of Change, Plague or Excess (as appropriate) if they wish. However, if they do so, then the rules for Chaos Focus (see BRB) no longer apply to them; they follow the normal rules for Psychic Focus instead.
