Wolf-kin of Russ

A unit containing Models with this Special Rule may never be joined by any Model other than Leman Russ.

"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 any Models with this Special Rule cannot claim Objectives."
A Unit that includes any Models with this Special Rule cannot Control or Contest any Object Marker - this overrides any other Rule or Special Rule that may apply to the Unit regardless of the source of the Rule or effect.

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.

"Feel No Pain (X) is a Damage Mitigation Test that may be taken in addition to a Saving Throw."
A Model with the Feel No Pain (X) Special Rule gains a Feel No Pain Damage Mitigation Test that may be used in Step 9 of the Shooting Attack process or Step 8 of the Initiative Step of the Fight Sub-Phase process to discard wounds allocated to the Model. A Damage Mitigation Test may be made after and in addition to a Saving Throw. The Target Number for a Feel No Pain Damage Mitigation Test is the value of X attached to the specific variant of the Special Rule.

"A Unit that only includes Models with the Fast (X) Special Rule gain a bonus to Rush and Charge Moves."
When the Player controlling a Unit that is composed entirely of Models with the Fast (X) Special Rule elects to have that Unit Rush, add the value of X attached to the specific variant of Fast (X) to the distance the Unit can move. Likewise, when a Unit composed entirely of Models with the Fast (X) Special Rule is required to make a Charge Move, add the value of X attached to the specific variant of the Fast (X) Special Rule as a positive modifier to the Charge Roll. In any situation where a Unit includes Models with two or more variants of the Fast (X) Special Rule, the lowest possible modifier is used.
