Your last fight against the Fell left you scarred. You cannot grasp the situation yet, but whenever you enter the Shroud, the choking fog suffocates you much quicker. You should ask the Alchemist about a cure to ensure this new ailment doesn't impact your vitality long-term.

Your talk with the Alchemist was enlightening, but disturbing just the same. You learned you were cursed on your last expedition into the Shroud.
