Mortarion

Enemy units within 7" of Mortarion must subtract 1 from their Toughness characteristic.

Roll a dice for each enemy unit that is within 7" of Mortarion at the start of the Fight phase and consult Mortarion's damage chart; if the roll equals or exceeds the required value, the unit being rolled for suffers D3 mortal wounds.

You may re-roll failed hit rolls of 1 made for friendly DEATH GUARD units within 7" of Mortarion.

Mortarion has a 4+ invulnerable save.

When Mortarion loses his last wound (after failing his Disgustingly Resilient roll), roll a dice before removing the model from the battlefield; on a 4+ he explodes, showering all nearby in putrid filth and disease - each unit within 7" suffers D3 mortal wounds unless it has the NURGLE keyword.

Each time this model loses a wound, roll a D6; on a 5+, the model does not lose that wound.

Each time you roll a hit roll of 6+ for a model with this ability in the Fight phase, it can, if it was targeting an IMPERIUM unit, immediately make an extra attack against the same unit using the same weapon. These extra attacks cannot themselves generate any further attacks.

Re-roll all failed wound rolls when resolving attacks made with a plague weapon (i.e. a plaguesword or any weapon with the Plague Weapon ability) for any friendly DEATH GUARD unit within 7" of your Warlord.
