Check out my review of the DLC here: Dishonored: The Brigmore Witches review
The Brigmore Witches is a DLC that continues Daud’s story, a story that suddenly ended without much resolution in The Knife of Dunwall. Much like the previous DLC, Brigmore is only 3 missions long and generally smaller in scope than the base game. Conveniently, you’re able to load your saves from The Knife of Dunwall into The Brigmore Witches, keeping your powers and current chaos level (which affects your ending, much like in the base game).
I made sure to get the “good” low-chaos ending by being stealthy in both DLCs, so be sure to check out my Knife of Dunwall screenshots.
