Culexus Assassin

Armour saves cannot be taken against Wounds inflicted by a Culexus Assassin's close combat attacks. Any close combat attack inflicted by a Culexus Assassin that rolls a 6 To Wound has the Instant Death special rule. Any close combat attack inflicted by a Culexus Assassin that is allocated to a Psyker has the Instant Death special rule.

Psykers, friend or foe, within 12" of a Culexus Assassin have -3 Leadership, do not generate any Warp Charge (i.e. they do not add dice to their owning player's Warp Charge Pool in the Psychic phase) and only harness Warp Charge points on a 6. A Culexus Assassin can never be targeted or affected by psychic powers - other units in the Culexus Assassin's vicinity that are hit by beam or nova powers, or by Witchfire powers that use templates, are hit/affected normally. Any blessing or malediction psychic powers affecting a unit immediately cease to be in effect if the unit moves within 12" of a Culexus Assassin or vice versa.

Units containing one or more models with the Fearless special rule automatically pass Pinning, Fear, Regroup tests and Morale checks, but cannot Go to Ground and cannot choose to fail a Morale check due to the Our Weapons Are Useless rule. If a unit has Gone to Ground and then gains the Fearless special rule, all the effects of Go to Ground are immediately cancelled.

At the start of each Fight sub-phase, a unit in base contact with one or more enemy models that cause Fear must take a Leadership test (called a Fear test) before any blows are struck. If the test is passed, all is well and there is no effect. If the test is failed, the unit succumbs to fear - all models in the unit have their Weapon Skill reduced to 1 for the remainder of that Fight sub-phase. Note that a model that causes Fear is not itself immune to Fear, and will still need to take a Fear test if it is base contact with any enemy models that cause Fear.

Units that contain at least one model with this special rule are deployed last, after all other units (friend and foe) have been deployed. If both sides have Infiltrators, the players roll-off and the winner decides who goes first, then alternate deploying these units.

Infiltrators can be set up anywhere on the table that is more than 12" from any enemy unit, as long as no deployed enemy unit can draw line of sight to them. This includes in a building, as long as the building is more than 12" from any enemy unit. Alternatively, they can be set up anywhere on the table more than 18" from any enemy unit, even in plain sight.

If a unit with Infiltrate deploys inside a Dedicated Transport, they may Infiltrate along with their Transport. 

A unit that deploys using these rules cannot charge in their first turn. Having Infiltrate also confers the Outflank special rule to units of Infiltrators that are kept as Reserves.

If a unit has both the Infiltrate and Scout special rule, that unit can deploy as per the Infiltrate special rule and then redeploy as per the Scout special rule.

A unit that contains at least one model with this special rule rolls an extra D6 when rolling to move through difficult terrain and is not slowed by charging through difficult terrain. In most circumstances, this will mean that, when moving, the unit rolls 3D6 and picks the highest roll. Furthermore, a model with the Move Through Cover special rule automatically passes Dangerous Terrain tests.

This rule is often presented as Preferred Enemy (X) where X identifies a specific type of foe. If the special rule does not specify a type of foe, then everyone is a Preferred Enemy of the unit. A unit that contains at least one model with this special rule re-rolls failed To Hit and To Wound rolls of 1 if attacking its Preferred Enemy. This applies both to shooting and close combat attacks.

A model with this special rule can never be joined by another character. If a model with this special rule is your army's Warlord, it never has a Warlord Trait.

A model with this special rule has a 4+ invulnerable save. In addition, they do not suffer the penalty to their Initiative for charging enemies through difficult terrain.

Enemy characters suffer a -2 penalty to their Look Out, Sir tests against any Wounds inflicted by a model with this special rule.
