Sacred Haven of Debauchery

Yes, I stumbled upon it a long time ago, and I even clicked on it, but I got stuck and gave up, despairing of farming a huge amount of gold. Then, in winter, I found it, read the wiki there, did as it said, and everything went well. And not so long ago, they released a patch that does something particularly crazy with the game, so just in case, I made a separate save and now I'm going to play it again from the beginning.
