So it looks to me that in most cases the issue of Poison has been settled; anything that reduces damage does not reduce poison, but poison may be prevented by spending a soul stone. What I don't see an answer for is how Poison interacts with Hard to Kill.
On one hand, Hard to Kill states that when the model "suffers damage, it may not be reduced below one wound." On the one hand, the choice of language seems to put Hard to Kill squarely in the realm of damage reduction such that it would not apply when the model is taking damage from Poison. On the other hand, the triggering condition in Hard to Kill seems to be the taking of the damage, not the limit on reduction Therefore a reasonable interpretation could also be that a model that she takes more damage from Poison than it has wounds, it would still only be reduced to one wound and not killed.
Though I'm a budding McMourning player, I'm really not advocating for either interpretation. I would just like to get the groups take on how this should play out.
thanks
