At the start of the battle, once both armies have set up all their models, including any units with the Infiltrator special rule, a player that controls any models with this special rule may select one of the effects listed below as part of this special rule. All units with the Kyropatris field generator item of Wargear in the Detachment that includes the model with this special rule gain the chosen effect for the duration of the battle. Note that only a single bonus may be given to the units, regardless of how many models with this special rule are present in the Detachment. If an army includes multiple Detachments that include any models with this special rule, the controlling player must select an effect for each such Detachment and may select the same or different effects for each Detachment: • Pain Suppression Override: Affected models gain the Feel No Pain (5+) special rule. • Explorator Synaesthesis: Models in affected units gain the Move Through Cover special rule. • Deconstructive Confluence: Models in affected units gain the Wrecker special rule. • Extinction Interlock: Models in the affected units gain the Preferred Enemy (Infantry) special rule.
When a model with this special rule suffers an unsaved Wound, it can make a special Feel No Pain roll to avoid being Wounded (this is a special Saving Throw which is made after unsaved Wounds are suffered). Feel No Pain rolls may not be taken against unsaved Wounds that have the Instant Death special rule. Roll a D6 each time an unsaved Wound is suffered. On a result that is equal to or greater than the value in brackets, the unsaved Wound is discounted - treat it as having been saved. On any other result the Wound is taken as normal. For example, a unit with the special rule Feel No Pain (5+) would need to score a 5 or 6 in order to discount a Wound inflicted upon it. This is a Damage Mitigation roll - any model may make only a single Damage Mitigation roll of any type for any given Wound (see page 174).
A unit that contains only models with this special rule suffers no penalty for moving or charging through Difficult Terrain.
Penetrating Hits caused by attacks made with weapons or models with this special rule add +1 to the result of any rolls on the Vehicle or Building Damage tables.
This rule is presented as Preferred Enemy (X) where X identifies a specific type of foe. If the special rule does no specify a type of foe, then everyone is a Preferred Enemy of the unit. A unit that contains at least one model with this special rule re-rolls failed To Hit and To Wound rolls of 1 if attacking its Preferred Enemy. This applies both to Shooting Attacks and close combat attacks. If a model with this rule makes an attack against a mixed unit which has one or more models to which their Preferred Enemy rule pertains, but is not entirely composed of such models, it may still benefit from the effects of Preferred Enemy for all attacks made against that unit. For example, a model with Preferred Enemy (Independent Characters) may re-roll failed To Hit and To Wound rolls of 1 against all of the models in a unit which has been joined by an Independent Character.
