Cross over the bridge to the right and then run down the center stairs to confront the red eye knight. Kill him to open the door to the next room and enter, where you can loot the corpse for a Large Soul of a Weary Warrior 2x. Head back up the stairs and on the left you will find a corpse up high with a Molten Soul of a Lightbringer 1x. Exit the room and in the next hall be sure to loot the chest behind the stairs to the left with an Essence of the Lightbringer 1x. The chest in the next room has a Titanite Scale 1x.
Return to the room with the cleric and two knights and keep heading down the stairs to the right. Loot the corpse hanging in the corner for an Ember 1x. If you are lucky and played correctly you will have gained ownership of all three capes and will be allowed to utilize them. Exit this room and head up the stairs past the stairs you just descended to where a walkway juts out. At the ledge on the left there is a corpse you can loot for an Essence of the Justice. To the right is a chest with a glowing blue hand that will allow you to upgrade your cape. With all your capes up and equipped this should look like so:
Now head up the walkway to a long, long narrow hallway that has a dead end that is covered by a wooden door. This door is guarded by a wyvern, which you can kill in order to continue. If you walk back through the hallway and continue down you will find the next room with some crossbow hollows which aren't so tough. Loot the corpse for a Lightning Urn 6x. To the right of the crossbow hollows is a chest with a Refined Gem 1x. d2c66b5586
