"On a successful Charge, a Model with the Impact (X) Special Rule temporarily increases a Characteristic by 1." If a Unit that includes any Models with the Impact (X) Special Rule or any Models that have any Weapons with the Impact (X) Special Rule, and that Unit makes a successful Charge, then this Special Rule is triggered. Once triggered, until the end of that Assault Phase, when making Melee Attacks for Models in that Unit, each Model or Weapon that is selected for one of those Models, that has a variant of this Special Rule, gains a modifier of +1 to any Characteristics that is the value of X.
"Models near an enemy Model with the Fear (X) Special Rule must reduce their Advanced Characteristics." When any Model from a Unit is within 12" of an enemy Model with the Fear (X) Special Rule, all Models in that Unit must reduce their Leadership, Willpower, Cool, and Intelligence Characteristics by the value of X. This negative modifier is removed as soon as no Models in a given Unit are within 12" of any Model with the Fear (X) Special Rule. If a Unit would be affected by multiple instances of the Fear (X) Special Rule, the value of X is not stacked and instead the single highest value is used as a negative modifier.
"A Unit that includes Models with this Special Rule scores fewer Victory Points for controlling Objectives, but can score Victory Points destroying enemy Units that hold Objectives." A Unit that includes a majority of Models with the Vanguard (X) Special Rule may only ever score 1 Victory Point for Controlling an Objective, regardless of that Objective's value (see Core Missions in the Warhammer: The Horus Heresy - Age of Darkness Rulebook). However, the Player that controls a Unit that includes a majority of Models with the Vanguard (X) Special Rule gains Victory Points equal to the value of the X in the Vanguard (X) Special Rule, in addition to any Victory Points scored for controlling an Objective, whenever either of the following two statuses are fulfilled: - If an attack made for a Unit that includes a majority of Models with the Vanguard (X) Special Rule causes the last Model in an enemy Unit that is Controlling or Contesting an Objective to be Removed as a Casualty. - If a Unit that includes a majority of Models with the Vanguard (X) Special Rule has at least one attack made for it in a Combat that results in one or more enemy Units that had at least one Model within 3"" of an Objective at the start of that Assault Phase either Falling Back from Combat or being Massacred. Note that the Vanguard (X) Special Rule may only be used to score Victory Points once per Objective per Player Turn - no matter how many enemy Units were Controlling or Locked in Combat near that Objective.
Models with the Bulky (X) Special Rule take up more space on Transport Models." A Model with the Bulky (X) Special Rule does not use up 1 Point of Transport Capacity when it Embarks on a Model with the Transport Sub-Type. Instead it uses up a number of points of Transport Capacity equal to the value of X attached to eh variant of the Bulky (X) possessed by that Model.
"The Deep Strike Special Rule allows a Unit to enter play anywhere on the Battlefield." A Unit that includes only Models with the Deep Strike Special Rule that enters play from Reserves may make a Deep Strike instead of deploying a described in the Reserves Rules. No more than one Unit may attempt a Deep Strike in a given Player Turn. The Unit attempting a Deep Strike may have another Unit without the Deep Strike Special Rule Embarked Upon it if the Deep Striking Unit includes models with the Transport Sub-Type (note that some Missions may allow more Units to attempt a Deep Strike in the same Player Turn. This will be specifically noted in the Mission Special Rules section of that Mission.) Note that in Missions where the Reserves Mission Special Rule is not in use, the Deep Strike Special Rule has no effect. Furthermore, Units may not make use of the Deep Strike Special Rule during the first Battle Turn, even if they enter play from Reserves. To perform a Deep Strike, the Active Player must declare an Eligible Unit that has entered play from Reserves in the Reserves Sub-Phase as the Deep Striking Unit. The Active Player must then select one Model from that Unit and place it anywhere on the Battlefield. This Model must be placed at least 1"" away from any enemy Model, Battlefield Edge or piece of Impassable Terrain. Once this first Model has been placed, the remaining Models in the Unit must be placed within Unit Coherency with at least one other Model in the same Unit and withing 6"" of the first Model placed. No Models may be placed within 1"" of an enemy Model, any Battle Field Edge or a piece of Impassable Terrain. Any Models that cannot be placed using these Rules must be Removed as a Casualty immediately. This deployment must take place during the Reserve Sub-Phase, and a Unit that deploys as a Deep Strike may not move in the Move Sub-Phase of the same Player Turn or have a Charge declared for it in the Charge Sub-Phase of the same Player Turn, but may make Shooting Attacks as normal. A Unit that is Embarked on a Model that is deployed as part of a Deep Strike may Disembark during the Move Sub-Phase of the same Player Turn, but may not make any move other than the move made to Disembark and may not have a Charge declared for it in the Charge Sub-Phase of the same Player Turn. Enemy Units may declare Intercept Reactions against a Unit deployed as part of a Deep Strike, but not Reposition Reactions.
