Don't forget to explore the surrounding area; you can unlock a shortcut from the "lodge" that is only a couple of mobs away from the lift that takes you to the torch. It saves a -shitload- of time if you have to run back. Admittedly, I one-shotted the boss there, but either way opening that short cut is a huge timesaver. For strats on the boss, just find my previous post where I mention "Shadow"
edit: killing Paarl means you are ahead of the game. Vicar is a joke comparatively, and you should do Shadows of Yarnham next if you haven't already. Then it is Rom and beyond.
