hmm looks familiar.
Lower Guk, Ghoul Scribe if I am not mistaken
Camped there many hours trying to get two monk martial weapons when I was still doing Guk. Minimized windowed timed sound effect every 15 minuets for pop and kill, over and over again
Atleast it is an enjoyable spot for everybody

Edit : that area might also be the Herbalist, without running down there to check. You better say so we can check our guessing skills
