"A Weapon with the Poisoned (X) Special Rule has a chance to cause a wound regardless of the target's Toughness Characteristic."
When making Wound Tests for Hits that have the Poisoned (X) Special Rule, if the result of any Dice rolled is equal to or greater than the value of X attached to the specific variant of this Special Rule then a wound is caused automatically, regardless of the Toughness Characteristic used to determine the Target Number. A Hit that has this Special Rule may still inflict a wound by passing a Wound Test as normal, instead of using this Special Rule, but never inflicts more than 1 wound if it would both pass the Wound Test and trigger the Poisoned (X) Special Rule. Wounds caused using the Poisoned (X) Special Rule retain the AP and Damage Characteristics of the Weapon and Saving Throws and Damage Mitigation Tests may be made to discard them as normal. The Poisoned (X) Special Rule has no effect on Models that have the Vehicle Type, and limited effect on Models with the Automata or Walker Types (See the Rules for Walkers and Automata in the Warhammer: The Horus Heresy - Age of Darkness Rulebook).

"Unsaved Wounds with the Phage (X) Special Rule reduce a Characteristic by 1."
If an attack made for a Weapon or Model with this Special Rule inflicts one or more Unsaved Wounds on a Target Unit, then once the Shooting attack or Initiative Step in which the Unsaved Wound was inflicted has been completely resolved, all remaining Models in the Unit that was the target of the attack must reduce the Characteristic that is the value of X for that variant of the Phage (X) Special Rule, but no individual Characteristic may be reduced by more than 1 by the Phage (X) Special Rule no matter how many Unsaved Wounds with any variant of that Special Rule are allocated to Models in that Unit.

"Attacks made with the Blast (X) Special Rule use a Blast Marker to determine how many Hits are caused."
When making attacks with a Weapon that has the Blast (X) Special Rule, before any Hit Tests are made, a Blast Marker must first be placed to determine how many Hits may be inflicted by the attack. The Player making the attack must place the Blast Marker indicated in brackets as part of the Special Rule so that the hole in the middle is entirely over the base of any one model in the Target Unit. Once the blast Marker has been placed, the Player making the attack must make a Hit Test for the attack, and each Model from the Target Unit that is fully or partially under the Blast Marker will suffer 1 Hit if the Hit Test is successful.

*Hits on Other Units*
If any Models form Units other than the Target Unit are fully or partially covered by the Blast Marker, then a new Fire Group must be created for those Hits and set to one side. Continue resolving the Shooting Attack on the original Target Unit, and once that Shooting Attack has been completely resolved begin a new Shooting Attack to resolve those additional Fire Groups generated for Units other than the original Target Unit.

If the Hit Test is unsuccessful then no Hits are inflicted and the Player making the attack must make a Scatter Roll for the Blast Marker (see the Rules for Scatter in the Warhammer: The Horus Heresy - Age of Darkness Rulebook). Once a Scatter Roll has been made for the Blast Marker and it has been moved, one Hit is inflicted on a Unit for each Model from that Unit that is wholly or partially covered by the Blast Marker.

"Weapons and other attacks that have the Stun (X) Special Rule have a chance of inflicting the Stunned Status on the Target Unit."
If a Shooting Attack made for a Weapon or Model with this Special Rule inflicts one or more Hits on a Target Unit, that Target Unit must make a Cool Check in the Morale Sub-Phase of the same Player Turn. If this Check is failed then all Models in the Unit gain the Stunned Status and if the Check is passed then there is no further effect. The value of X attached to this Rule is applied as a negative modifier to the Cool Characteristic of Models in the Target Unit when making Checks caused by an attack with this Special Rule, if the attack includes multiple Weapons with different versions of this Special Rule the modifiers do not stack - use only the greatest modifier.
