If every unit from your army has the DEATH GUARD keyword (excluding UNALIGNED units), this unit gains the following ability:

Nurgle's Gift (Contagion): While an enemy unit is within Contagion Range of this unit (see below), subtract 1 from the Toughness characteristic of models in that unit.

Inexorable Advance

- This unit counts as having Remained Stationary if it did not Fall Back or Advance in your previous Movement phase.
- If this unit has the VEHICLE keyword, it does not suffer the penalty incurred to its hit rolls for firing Heavy weapons at enemy units that are within Engagement Range of it.
- If this unit has the INFANTRY keyword, it can ignore any or all modifiers to its Move characteristic, Advance rolls and charge rolls.

Abilities
Blight Racks (Aura)
While a friendly BUBONIC ASTARTES unit is within 6" of this model, blight grenades models in that unit are equipped with have an Armour Penetration characteristic of -1 and a Damage characteristic of 2.
Disgustingly Resilient
Each time an attack is allocated to a model in this unit, subtract 1 from the Damage characteristic of that attack (to a minimum of 1).
Foul Infusion
Once per turn, at the start of either your Charge phase or the Fight phase, you can select one friendly CORE unit within 6" of this model. Until the start of your next Command phase, each time a model in that unit makes a melee attack with a Plague Weapon, an unmodified wound roll of 6 inflicts 1 mortal wound on the target in addition to any normal damage. Each unit can only be selected for this ability once per turn.
Putrid Explosion (1MW)
When this model is destroyed, roll one D6 before removing it from play. On a 4+ it explodes, and each unit (excluding NURGLE units) within 6" suffers 1 mortal wound.
