This section of the guide complements the overall Eleum Loyce guide.
Use one of your Flame Butterfly's to set fire to the pedestals here. If you don't have one of these items, go back to the room with doors at each end (back where you battled the Frozen Hound and Soldiers), then take the door on the far side. The next room along contains a pedestal that's already been lit, and you can use your torch to carry the flame back. If you need a torch, kill the Prisoner who's just opposite from the Abandoned Dwelling bonfire.
When the door's open, go through it but be ready to deal with seven Retainers. We recommend firing ranged attacks at them from a position of safety at the door, and then finishing them off as they drop down and head towards you.
Examine the door outline in the rocks to your left, then go up the path and take a left. Take the weapon here, then head back down the path and into the next passage to begin a fight against a Flexile Sentry.
When it's dead, take the passage on your left, then look down to where the next Flexile Sentry waits. Fire a shot at it, let it charge up towards you, and then just keep firing until the monster falls to the floor. Take the Human Effigy items nearby, then jump down into the bottom area and pinch the Garrison Ward Key that was being guarded.
