Stratagem: The Cult's Psyche

Use this Stratagem before the battle. Select one MAGUS unit from your army. That unit can attempt to manifest one additional psychic power in your Psychic phase. When a Psychic test is taken for that unit, add 1 to the total for each other friendly PSYKER unit within 3" (to a maximum of +3). You can only use this Stratagem once per battle.
