Sigismund

During the Controlling Player's Challenge Sub-Phase, if Sigismund is eligible, he must be declared as the Challenger.
If more than one Model under the Active Player's control in a Combat must be the Challenger, they must select Sigismund as the Challenger.

Additionally, when the Controlling Player issues a Challenge for Sigismund (including as part of the Heroic Intervention Advanced Reaction), they may select which of the Opposing Player's eligible Models is the Challenged. If, for any reason, the selected enemy Model cannot be the Challenged, Sigismund's Controlling Player gains a number of Combat Resolution Points equal to the starting Wounds Characteristic of the selected enemy Model that did not become the Challenged, and Sigismund's Controlling Player may select an alternative eligible Model to accept the Challenge.

While a Model with this Special Rule is engaged in a Challenge, its Controlling Player can select the following Gambit:
Death's Champion: If this Gambit is selected, attacks made by this Model in the following Strike Step have the Critical Hit (5+) Special Rule.

"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.

When making a Shooting Attack for a Unit that only includes Models with this Special Rule, add +1 to the result of Hit Tests made for attacks in any Fire Groups that include more than five Dice or attacks and that have the Bolt or Auto Trait.

"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.
