Description: May only be used when in base contact with an enemy psyker. Before fighting each round of close combat the psyker should roll 2D6 and add his Leadership characteristic to the score. The Culexus Assassin should roll 3D6, choose the two highest dice and add his Leadership score. If the scores are drawn or the Culexus Assassin loses, the attack has no effect and close combat continues as normal.
For each point that the Culexus Assassin beats the psyker's score by, he can drain 1 point from any one of the victim's WS, BS, S, T, or LD. If any of the psyker's characteristics are reduced to 0, then the psyker is killed and removed as a casualty. Drained characteristics are lost for the rest of the of the battle.
If in close combat with multiple psykers, test for each one.
