My experience is that not every adventure stacks on Shadow points.tigermuppetcut wrote:The reason the question came up is the Marsh Bell actually requires a lot of travel and searching in a Blighted place and the players were racking up Shadow points pretty quick, and that is an introductory adventure.
So, I think it's alright to gain lots of Shadow points in one adventure if the theme deserves it (visiting Dol Guldur, or entering the Inner Sanctum of Dwimmehorn), while in other adventures (Of Leaves and Stewed, Kinstrife,...) the group won't probably gain any Shadow point unless they misbehave.
After all, the Heal Corruption Undertaking exists for some reason and it makes more sense after a harrowing experience.
