The gnoll fort was a notorious spot for early leveling. Yet, I want to focus on one element in particular: Falling down that damn cave. At the bottom of Blackburrow sits a bunch of flesh hungry fish and a few ST mobs that will make quick work of any character they can kill on site.
It was an accepted fact that if you fell to the bottom, your group was not going to follow you down. Your fault. Your death. Good luck and good riddance!
One additional thing about Blackburrow: the always guaranteed BSOD. I’d like to think this was from so many mobs in the zone but whenever you traveled up the river from DM toward Mt. Hatespike, it was a given that at least one person would bsod.
