If you played The Knife of Dunwall, here's a few FAQs re: transferring your save to The Brigmore Witches.
How a transfer save is created:
After a user completes The Knife of Dunwall content, a save will be made in either High Chaos or Low Chaos, depending on the status at the end of the content. You are able to have both a High and Low Chaos save to carry over to The Brigmore Witches. Note: These saves are only visible through the Dashboard/XMB, not from within the game.
How to use a transfer save in the The Brigmore Witches:
When choosing to start a New Game in The Brigmore Witches, a prompt will appear that will allow you to select High Chaos, Low Chaos, or New Game. The High and Low options will port over your character’s inventory from the previous DLC, and there will also be certain events throughout gameplay that will be affected by the chaos level transferring over. You will be able to gather this transfer inventory when collecting the Wristbow and Sword from the chest
