ERUPTION OF FILTH

Use this Stratagem in any phase, when a
DEATH GUARD CHARACTER model from
your army is destroyed instead of using any
other rules that are triggered when a model is
destroyed (e.g. the Putrid Explosion ability).
Before removing that model from play, roll
one D6 for each other unit within 3" (excluding
NURGLE units): on a 2-5, that unit suffers
1 mortal wound; on a 6, that unit suffers D3
mortal wounds.
