Infernal Engine

Friendly models in units within 12"* of a non-Shaken friendly model with Commanding Presence set their Discipline to that model’s Discipline: apply any modifiers to the Discipline of the model with Commanding Presence first, then set any affected models’ Discipline to that modified value (note: ignore this rule if the model’s original value is higher).
If any rules, properties, unit names, etc. are mentioned in brackets (X), it means that only units possessing these qualities can benefit from the model’s Commanding Presence.
*Unless there is a distance in the bracket, then use that instead.

A unit containing Fearless automatically passes Panic Tests, cannot choose Flee! as a Charge Reaction (unless it is already Shaken, or the entire unit has Feigned Flight).
In addition it ignores the effects of Horror.

The model cannot choose to Pursue, unless it is its First Round of Combat and it is Charging. In that case, it must Pursue (including Overrun).

Units containing Solitary can never join other units, and can never be joined by other models.
Note: if a model has both Solitary and Attached, it cannot be Deployed and is therefore considered a casualty.

When a unit containing Stubborn loses a Round of Combat, halve the penalty to its Discipline from the Combat Score difference, rounding fractions up (i.e. towards a larger modifier).
If the unit is also Steady, the modifier is first set to no smaller than −2 (following the Steady rules), and then halved, rounding up, to −1.
If the unit is Unstable, the Health Point losses due to Unstable are halved, rounding fractions up (i.e. towards more Health Point losses).

When a unit containing Terror declares a Charge in the Charge Phase, the target must take a Panic Test. If the test is failed, the unit must choose Flee! as its Charge Reaction if allowed to do so (e.g. not already Engaged in Combat, etc.).
Units containing Terror are themselves immune to the effects of Terror.

Whenever a unit entirely with Unstable would take a Break Test, it suffers instead a number of Health Point losses equal to the amount by which the Combat was lost (with no saves of any kind allowed). These Health Point losses are first allocated towards Rank-and-File models, and once enough Health Points losses are suffered to remove all Rank-and-File models, any remaining Health Point losses are allocated by the owner towards Attachable Models, as evenly as possible. Those Health Point losses can be reduced in the following ways:
  • If the unit contains Stubborn, the Health Point losses are halved, rounding fractions up.
  • If the unit is affected by Beacon of Courage, the Health Point losses are reduced by 1.
  • If the unit is Steady while affected by Beacon of Courage, the Health Point losses are reduced by an additional 1.
  • If the unit is Solid while affected by Beacon of Courage, the Health Point losses are reduced by an additional 1. I.e. a unit that is affected by Beacon of Courage while also being Steadfast reduces its Health Point losses by a total of 3.
Attachable Models with Unstable can only join units containing Unstable, and units containing Unstable can only be joined by Attachable Models with Unstable.

A Charging model part with Devastating Charge, or using a weapon with Devastating Charge, gains the Rules and Characteristic modifiers stated in brackets.
For example, a model part with Devastating Charge (+1 Str) gains +1 Str when Charging.

A model part with a Grind Attack can make a Special Attack which is resolved at the model part’s Agility, and inflicts X hits, using the model part’s Strength, Armour Penetration, and Attack Attributes, but not Weapons.
Remember that attacks multiplied into several hits are allocated after establishing how many hits are scored (i.e. after the attack has hit).

During Combat Choices a model part can only choose Innate Weapons if it has no other options.
All model parts with Beast, Construct, or Mount come equipped with Innate Weapons as their default equipment and cannot lose them.
