Instead of using the Animus Speculum, the Culexus Assassin may throw a psyk-out grenade. They have a range of 6". Roll to hit as normal. If an enemy psyker is hit by the attack, he must pass a Leadership test on a 2D6. For each point the psyker fails the test by, he loses 1 Wound. Saving throws can be taken as normal.
