Etherium: Any unit wishing to shoot at or charge the Culexus Assassin, and any psyker trying to target him with a psychic power, must first pass a Leadership test, if the test is failed they may attack another target instead.

Animus Speculum: The animus speculum has the following profile. For every psyker within 12" of the Culexus Assassin, add +1 to the animus speculum's Assault value (i.e. Assault 2 becomes Assault 3 if there is one psyker within 12").

Psyk-Out Grenades: Instead of firing the animus speculum, the Culexus Assassin may throw a psyk-out grenade. This is only useful against psykers. Psyk-out grenades have a range of 6". Roll to hit as normal. If the psyker is hit, they must pass a Leadership test on 2D6. For each point the psyker fails the test by, they lose 1 Wound. Saving throws may be taken as normal. For example, a psyker (with Ld 7, due to the Soul/ess rule, opposite) rolls 9, and so loses 2 Wounds.

Psychic Abomination: Any psyker within 6" of the Culexus Assassin at the start of their turn must pass a Morale check or fall back. If they are with a unit, then the unit will also fall back.

Soulless: Any unit (friend or foe) with a model within 12" of the Culexus Assassin counts as having Leadership 7, unless it would normally be less than this.

Psyker Assassin: The Culexus Assassin can always target a psyker specifically with any shooting attacks, regardless of whether the psyker is in a unit, an independent character, etc. The Culexus Assassin may ignore other models when charging into an assault if this will allow it to get into contact with a psyker.

Life Drain: The Culexus Assassin may use this ability when in close combat with a psyker. Before any attacks are worked out, but after models are moved, both players roll 2D6 and add the Leadership value of their respective models (remember the Soulless rule, above). If the Culexus Assassin scores higher, the psyker loses one Wound, with no saving throws of any type allowed (not even invulnerable saves). This is worked out at the start of every round of close combat and Wounds inflicted by this attack count towards the combat resolution. All other close combat attacks are worked out
