I'm working on the Scent of Incense quest in Flotsam (Chapter 1). I got the real recipe and talked with the scholar. I refused to be blindfolded, so he marked the location of his laboratory on my map.
Unfortunately, I can get close to the marker, but I can't seem to find a way to actually reach it. I've gone up and down the path with the two bandit groups (the way to the field full of Kayran mucus.
I also tried searching around the other path in the area, which leads to the graveyard area a little ways outside town. All to no avail.
How do I get to the laboratory and get my reward?
