Do terrain keywords stack?

[BreastsofFury]

If a unit was within short range of two corpse piles (Horrific) would it suffer -2 to moral tests or just 1? Same goes for other terrain features. If a unit would have to move through two terrain pieces with the "rough" keyword, would it then suffer -2 to it's movement?

I know abilities with the same name do not stack, but what about keywords?

I feel like keywords should stack just because two hedges would slow someone down more than one. Just as more dead bodies would be spookier.

No, because they have the same name for the keyword (Horrific). There's a tactics card that creates special corpse piles that I think the Weeper and a version of Dany has. Those corpse piles have a different named keyword - and those *would* stack.
