Immunity means that they won't receive the debuff, hence why I mentioned Glykins and confirmed by Dev too in one of those Balance-Fus about Glykins, once when I asked 'Why can't Glykins be affected by Poison, but have 100% resistance and thus take 0 damage from it?'.

It works like this to their Poison Immunity, they can't get the debuff by any means.
