"If a Model with this Special Rule is outnumbered, it gains extra attacks."
If a Model is outnumbered in Combat and either has this Special Rule or is made to attack with a Weapon that has this Special Rule, then that Model gains a bonus to its Attacks Characteristic equal to the value of X attached to the variant of this Special Rule it has access to. To be considered outnumbered, the total number of friendly Models Locked in Combat in the same Combat must be less than the total number of enemy Models Locked in Combat in the same Combat - Models with the Bulky (X) Special Rule count as a number of Models equal to the value of X in the Variant of the Bulky (X) Special Rule that Model has. This Special Rule has no effect during the Challenge Sub-Phase, and no Model that is Engaged in a Challenge may gain additional Attacks due to this Special Rule.

"A Model with this Special Rule takes less Damage from attacks."
When a Model with the Eternal Warrior (X) Special Rule is allocated an Unsaved Wound, the Damage of the Unsaved Wound is reduced by the value of X attached o the specific variant of the Eternal Warrior (X) Special Rule. The effects of this Special Rule cannot reduce the Damage of an Unsaved Wound to less than 1, regardless of the value of X.

"Attacks made with the Precision (X) Special Rule are allocated by the Attacking Player, not the Defender."
When any Hit Test is made for an attack with the Precision (X) Special Rule, if the result of the Dice roll, before any modifiers are applied, is equal to or great than the value of X attached to this variant of the Precision (X) Special Rule, then if a Hit is inflicted by that roll, that Hit becomes a 'Precision Hit'.

These Precision Hits must form a separate Fire Group or Strike Group. Wound Tests are made as normal for Precision Hits and cause Precision wounds. In Step 8 of the Shooting Attack process or Step 7 of the Initiative Step sequence, when selecting a Target Model for a Fire Group or Strike Group that is made up of Precision wounds, the Target Model is not selected using the normal Rules. Instead the attacking Player chooses which Model in the Target Unit will be the Target Model, and may select any Model that is a part of that Unit.

Note that Models Engaged in a Challenge cannot use this Special Rule to allocate Hits to any Model other than the enemy Model that is Engaged in the same Challenge and that any attacks which are made as Snap Shots, or for Weapons or attacks that have either the Blast (X) , Barrage (X), Template or Reaping Blow (X) Special Rules, may never trigger the Precision (X) Special Rule no matter what the result of the Hit Test is.
