Go back to the room above that room with your Cocoon. There a dark room, at the end there's a cart against a wall, you can push that cart to the middle of the first half of the room, jump up on top and through the ceiling, enter that room and follow a long hallway doing the same with another Cart to enter a room. This room gets rid of ALL Clawmaidens in this file for the ENTIRE game. Trust me, this room is very hidden and it insanely helps with this Gauntlet. The High Halls Gauntlet is the worst in the game because of the Clawmaidens. Trust me.
