I'm working on my staff of herding quest and have a question. I read that Black Mushrooms can be farmed from Act 1 - Cathedral 1. I have been replaying Cathedral 1 under adventure mode over and over again, at least 20 times now and still no black mushrooms appearing in any of the rooms. I saw a youtube video that stated that they can appear though levels 2-4 also but less likely but some thing again.
There is only one room for the Mushroom to appear, it has to fit into a corner. That means that the waypoint must be at another corner, with a path leading to the right. It's only cathedral 1. There are many guides, and probably Youtube videos on the Herding - has Izzy dropped the formula yet?
There is probably a local posting here on the Staff, the diablo wikis have some good detail, and icy-veins looks like he took his from the wikis. jfgi
