The Reliquary of Dust

"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).

"With a Weapon that has a Breaching (X) Special Rule there is a chance that a Wound Test may result in the Wound ignoring Armour Saves."
When any Wound Test is made for an attack with the Breaching (X) Special Rule, if the result of the Dice roll, before any modifiers are applied, is equal to or greater than the value of X attached to this variant of the Breaching (X) Special Rule, then if a wound is inflicted by that Wound Test, that wound becomes a 'Breaching Wound'.

A Breaching Wound is always treated as having an AP of 2 regardless of the Characteristics of the Weapon used to make the attack.

"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.

"A Weapon with the Limited (X) Special Rule can only be used to attack a limited number of times per Battle."
A Weapon with the Limited (X) Special Rule may only be used to make attacks as part of a Shooting Attack or Combat a number of times equal to the value of X attached to the specific variant of the Special Rule. Each time is used to make attacks, the Firepower Characteristic or Attacks Modifier Characteristic of the Weapon not modified by this Special Rule, only the number of times it may be selected in a given Battle.
