Psychic Scream

Every enemy psyker within 36” of the user must roll 2D6; if the score is greater than the roller‘s Toughness but under his Leadership, he is stunned by the scream and incapable of using any Warp Cards or taking any actions until the start of the next psychic phase. Stunned psykers fight in hand-to-hand combat with a WS of 1. If the roll is greater than the psyker‘s Leadership, the model goes insane and takes no further part in the battle — remove the model as an effective casualty.
