Mortarion

At the end of your Movement phase, roll one D6 for each enemy unit within 6" of this model, adding 1 to the result if that unit is Afflicted; on a 3+, that enemy unit suffers D3 mortal wounds.

Once per turn, this model can use one of the Lord of the Death Guard abilties.

While this model has 1-6 wounds remaining, each time this model makes an attack, subtract 1 from the Hit roll.

If your Army Faction is DEATH GUARD, while an enemy unit is within Contagion Range of one or more Death Guard units from your army, it is Afflicted.

CONTAGION RANGE 1st Battle Round: Contagion Range = 3" 2nd Battle Round: Contagion Range = 6" 3rd Battle Round Onwards: Contagion Range = 9"

Contagion Range cannot be greater than 12" after modifiers.

AFFLICTED

During the Declare Battle Formations step, select one of the Plagues below. Until the end of the battle, while an enemy unit is Afflicted, subtract 1 from the Toughness characteristic of models in that unit, and that unit has the effect of your chosen Plague.

Skullsquirm Blight Each time a model in this unit makes a melee attack, subtract 1 from the Hit roll.

Rattlejoint Ague Worsen the Save characteristic of models in this unit by 1.

Scabrous Soulrot Worsen the Move, Leadership and Objective Control characteristics of models in this unit by 1 (this rule can only worsen a model's Objective Control characteristic to a minimum of 1).

This ability always takes the form Deadly Demise X. Each time a model in this unit is destroyed, after the units embarked within it (if any) have made their emergency disembark moves, roll one D6. On a 6, that model suffers a deadly demise; each unit within 6" of that model suffers a number of mortal wounds denoted by X (if this is a random number, roll separately for each unit within 6").  Example:* An Impulsor with a unit of Intercessors embarked within it is destroyed by ranged attacks. First, any unresolved attacks made by the attacking unit are resolved. Then the Intercessors make an emergency disembark move. Then the roll is made for the Deadly Demise* ability, and on a 6, that ability is resolved. Finally, the Impulsor is removed from the battlefield.

This ability always takes the form Feel No Pain X+. Each time a model with this ability would lose a wound, roll one D6: on an X+, that wound is not lost. 

Each time this unit makes an ingress move (20.04), if every model in this unit has this ability, it can be set up anywhere on the battlefield that is more than 8" horizontally from all enemy units, even if that is within your opponent’s deployment zone.

Each time an attack made with a [LETHAL HITS] weapon results in a critical hit, you can choose for that attack to automatically wound the target.  Designer’s Note:* Choosing to automatically wound the target means that no wound roll is made for that attack. You may decide against this, as it means that attack cannot result in a critical wound* and so cannot trigger other abilities such as [DEVASTATING WOUNDS].

Each time an attack made with a [DEVASTATING WOUNDS] weapon results in a critical wound, the attack sequence for that attack ends and the target unit suffers a number of mortal wounds equal to the D characteristic of that weapon. These are inflicted after resolving any normal damage inflicted by those attacks.  Mortal wounds inflicted by [DEVASTATING WOUNDS] weapons can damage a maximum of one model for each critical wound; any remaining mortal wounds inflicted by that attack are lost.  Example: An attack made with a [DEVASTATING WOUNDS] weapon with a D characteristic of 3 results in a critical wound against an Intercessor Squad, so inflicts 3 mortal wounds. The first 2 mortal wounds are sufficient to destroy 1 Intercessor model, so the remaining mortal wound* is lost.

Each time you gather attack dice for a [BLAST] weapon, add one additional attack dice for every five models that were in the target unit in the Select Targets step (rounding down). If this ability takes the form [BLAST X], each time you gather attack dice for such a weapon, add X additional attack dice for every five models that were in the target unit in the Select Targets step (rounding down) instead.  Example:* If a [BLAST 2] weapon with an A characteristic of 3 targets a unit containing 12 models, you would gather four additional attack dice* for that weapon (for a total of seven for that weapon).

Each time an attack is made with a [PSYCHIC] weapon, you can ignore any or all modifiers to that attack’s BS or WS characteristic and any or all modifiers to the hit roll. Attacks made with [PSYCHIC] weapons are known as psychic attacks (this can be important for the triggering of other rules).

[PISTOL] and [CLOSE-QUARTERS] are identical for all rules purposes. 

Units containing one or more models with a [CLOSE-QUARTERS] weapon can shoot using close-quarters shooting (10.06). When using another shooting type, for each model in that unit (excluding MONSTER/VEHICLE models), you can only select one of the following to make attacks with:  - One or more of its [CLOSE-QUARTERS] weapons.  - One or more of its other ranged weapons.

This ability always takes the form [SUSTAINED HITS X]. Each time an attack made with a [SUSTAINED HITS] weapon results in a critical hit, that attack results in a number of additional hits on the target as denoted by X. Example: An attack made with a *[SUSTAINED HITS 2] weapon results in a critical hit. That attack therefore hits the target three times (once from the critical hit, and twice more from the [SUSTAINED HITS 2] ability).
