Bloat Fly

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 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.

Units entirely with Fly ignore Terrain Features, Open Terrain and other units during Move Manoeuvres and Charge Moves.
The unit must follow the Unit Spacing rule at the end of any of its moves, and Terrain Features and Open Terrain from which the model starts or ends its move still affect it.
The charged unit is not ignored during a Charge Move, and there must be room for the unit’s Front Facing to be placed in contact with the charged unit before the Initial Align Move.

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

Each time a model with Acid Blood loses a Health Point after failing a Regeneration Save against an enemy Melee Attack, it immediately inflicts 1 hit with Toxic Attacks towards the Health Pool of the attacking model, before any casualties are removed.

Aegis is a Special Save, with a value indicated in brackets (X).
If X is given as a modifier and with a maximum value (e.g. +2), the model gains this as a modifier to all its Aegis Special Save rolls, which can never be increased to rolls better than 3+. If the model does not have Aegis, it instead gains Aegis (7 X+). For example, a model without Aegis that gains Aegis (+2) will gain Aegis (5+).
Note that Aegis Saves cannot be taken against attacks with Divine Attacks.

Regeneration is a Special Save, with a value indicated in brackets (X).
If X is given as a modifier and with a maximum value (e.g. +2), the model gains this as a modifier to all its Regeneration Special Save rolls, which can never be increased to rolls better than 3+. If the model does not have Regeneration, it instead gains Regeneration (7 X+). For example, a model without Regeneration that gains Regeneration (+2) will gain Regeneration (5+).
Note that Regeneration Saves cannot be taken against attacks with Flaming Attacks, nor against attacks with Lethal Strike that roll a ‘6’ to wound.

A model part with Stomp Attack can make a Special Attack which is resolved at Agility Step 0, can only be allocated towards a Health Pool of Height 0–1, and inflicts X hits, using the model part’s Strength, Armour Penetration and Attack Attributes, but not Weapons. If more than one model part of a combined model has Stomp Attack, only a single model part (chosen by the model’s owner) can perform its Stomp Attack in each Round of Combat.

This Attack Attribute does not confer any direct effects, but instead interacts with other rules, such as Aegis (X, against Magical Attacks).

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.
