Jumping over the table
Upon clearing the outer guards you will probably notice your Mortal gold is a sea of red, your group will very carefully need to jump down to the left rather than go down the stairs or attempt to pull monsters out of the room. You will land in a three-pack of monsters which is by far the easiest route. After clearing these rooms you should be able to avoid the two banshees on the wall by jumping over the table, hang to the left side until you get to Butler Luitart.
