Hello!
So during a few run ins with Nurgloth (And even a successful one, so much for being undefeatable!) i noticed an issue with the handmaiden dash in that room.
For some reason the ground is uneven or has barely visible obstacles that when you dash into them result in kind of a rubberband effect, you pull into it with all your might but then you end up getting moved back… or the dash does not go anywhere at all.
It happens in multiple spots in that room.
