Well, I guess it is indeed a global modifier (not applying debuff as such) - NF confirmed it this morning: "Passively ongoing effects that change the state of the battle such as your Demon Spawn's heal reductions do not count as individual applications."

But I disagree with such approach - it should be applied as a debuff (not only because of this event, but generally). I am not aware of any other such "global modifiers" - everything is being amended through visible buffs/debuffs (unless it is a talisman skill). What also doesn't help is that sometime they name the skills in different wording and it is then confusing whether the skill applies or not.
