When you're done leave Ashley for a while head to the Hallway of Knighs. Dodge the axes thatcome your way and grab the King's Grail from the center pedestal. Four knights will arise as a result of this so kill them all and take out the next four that will arrive.
Back at the merchant's room go to the west door with the four switches and statues. Push the statues over the two switches, have Ashely stand on the other while you stand on the remaining switch to open the next doorway. Entering the room, the ceiling will start falling. Target the four red lights around the spikes to stop this. Then on to the next hall and have the gate crash in front of Ashley.Take down the two creepos there and the gate will reopen. Get the Queen's Grail in this room and return to the merchant's hall.
