I've got a quick question, in a French forum we have a discussion about the Death guard stratagem 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.
In my opinion, every DG character can use this at death door. BUT if this character is Mortarion or a Biologicus, he will not explode with the Putrid Explosion on top of that.
Other believe that Mortarion and the Biologus are the only character who can be affected by this Strategem (because of the "instead of using any other rules that are triggered when a model is destroyed"). And you cannot use Eruption of Filth on a Lord of Virulence/contagion, Daemon prince or any other DG character.
So I'm asking the English native speaker : who is right ?
