He Who Runs Away... The Magus can make a Voluntary Fall-back by making a successful Leadership Test, leaving his Bodyguard to keep on fighting in an Assault. He will automatically Regroup after this movement has ended, or if he reaches the edge of the board.
Hypnotic Gaze Use during any Assault Phase after all models have moved but before any combat takes place. If the Cult psyker passes the Psychic Test, choose an enemy model in base contact. That model will need to roll 6's to hit in Assault that round. If the Psychic Test was successful, and the roll was higher than the enemy model's leadership, then the enemy cannot strike any blows at all.
