When a unit entirely with Supernal fails a Break Test, instead of being Broken and subsequently Shaken, it suffers 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.
Attachable Models with Supernal can only join units containing Supernal, and units containing Supernal can only be joined by Attachable Models with Supernal.

A unit entirely with Ghost Step ignores Terrain Features and Open Terrain when moving.
The unit must follow the Unit Spacing rule at the end of its move.
A Health Pool with Ghost Step never fulfils the criteria for which models must take Dangerous Terrain Tests due to Terrain Features (but still needs to take Dangerous Terrain Tests from other sources than Terrain Features, such as when making a Flee Move through an enemy unit).
If the unit ends a move inside Impassable Terrain, backtrack the move to the unit’s last valid position, unless as part of a Flee Move, in which case the standard Flee Moves rules apply.

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.

Any unit entirely with Ambush may choose to not be Deployed normally, but to be placed in Ambush by simply not being placed on the Battlefield during Deployment. A unit placed in Ambush will arrive on the Battlefield later during the game.
From your Player Turn 2 and onwards, roll a D6 for each unit placed in Ambush at the start of the Movement Phase: every unit that rolls a 3+ will arrive on the Battlefield if possible.
During your Player Turn 5 and 6, this roll is always considered to have rolled a 3+.
When a unit arrives on the Battlefield, choose a point as specified by X. If no suitable point is available where the unit can be placed on the Battlefield, the unit cannot arrive on the Battlefield this turn.
Deploy each unit arriving on the Battlefield with at least three of its four corners within 6" from the chosen point in any valid formation following the Unit Spacing rule.
There must be no other units or Impassable Terrain directly located between any point on the Unit Boundary and the chosen point. See the figure below for examples.
Ambushing units count as having performed an Advance Move when they arrive on the Battlefield, and cannot perform any Move in the same Phase.
If an Ambushing unit does not arrive on the Battlefield by the end of the game, it is removed as a casualty.
An Attachable Models placed in Ambush can be Deployed joined to a unit placed in Ambush with the same X value, following the usual restrictions. It may choose a unit to be joined to during each of your Player Turns, before rolling to see if your Ambushing units arrive on the Battlefield.
Make a single dice roll for the Combined Unit.
Note: Attached has no effect on this; the choice of a unit to be Deployed in Ambush in may change each turn.

A unit arriving on the Battlefield in Game Turn 6 loses Scoring. Deploying Ambushing units.In these examples, the unit has Ambush (Battlefield Edge). The unit with the yellow check mark is placed in a valid position, while the two units with red crosses are not: the left one because there is an Impassable Terrain Feature between the Unit Boundary and the chosen point, and the right one because parts of the unit are more than 6" away from the chosen point.

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.

Rolls for Charge Range, Flee Distance and Pursue Distance by units entirely with Swiftstride gain Maximised.

A model with Shield is considered to be using a Shield at all times, except during the Melee Phase if it is using a Two-Handed Melee Weapon.
A model using a Shield gains +1 Arm.
In addition, any Height 1-3 model using a Hand Weapon while using a Shield gains Parry.
Note: Shield provides no benefit against Melee Attacks when using a Two-Handed Melee Weapon .
Remember that since Shield (and parry) provide modifiers to Defensive Characteristics, their effects do not apply to a Character on a mount that has its own Defensive Skill or Armour.

During Combat Choices a model part can only choose a Hand Weapon if it has no other options, or is a Weapon Master.
Models with a Shield using a Hand Weapon gain Parry.
All model parts without Innate Weapons come equipped with a Hand Weapon as their default equipment and cannot lose it.
