Before generating powers for models from a War Coven, you can choose a single cult of ancient Prospero from those listed below. All units in the Formation then count as having beloned to that cult, and harness Warp Charge points on a 3+ when attempting to manifest psychic powers from their cult's associated psychic discipline: Pavoni - Biomancy Corvidae - Divination Pyrae - Pyromancy Raptora - Telekinesis Athanaeans - Telepathy
If this formation contains the maximum number of units, then units from the Formation can re-roll any falied saving throw of 1.
