I was wondering how I am supposed to go about adding OL cards from expansions to the OL deck during a campaign.
Exactly as it says in the corresponding expansion (ie add in all non-treachery cards).
I've got all the expansions now, which makes for quite a few cards ( spawns, for example ) that have to be added to the deck. I'm wondering if this doesn't significantly lower the difficulty for the heroes, since I will cycle through my deck less often. Am I supposed to maintain a certain number in my OL deck ? Or do I just add these cards?
The the OL is more than compensated for his increased deck size by the more varied cards available and the ability to use treachery, and a wider variety of monsters.
And if the heroes are halfway competent the increased deck size will make no difference at all in 90% of dungeons.
Which is another way of sayig that if the heroes are still in the dungeon when 36 cards have been drawn then they are playing badly, for the most part.
