Psychic Scream

This power functions continuously and does not require a Psychic test to use. Any enemy units with models within 12" of a creature with this power suffer a -1 modifier to all Leadership based tests, including Morale checks and Pinning tests. If several creatures with the Psychic Scream power are within range of the unit, the modifiers are cumulative. Enemy psykers within range suffer the modifier to their Ld when testing to use psychic powers, and any failed Psychic test means they suffer an attack from the Perils of the Warp just as if they had rolled a 2 or 12.
