Talk:Madness mutagen/@comment-128.106.128.142-20180629092049

after extensive research and farming, it seems these madness shit actually drops on any average monsters. ive heard some guy got it off a drowner during the prologue. Nekkers, Endregas, Wraiths, Harpies too. So ANY monster that drop mutagens can drop the madness. its just that the drop rate is goddamn low, you need to farm many hours to get a meaningful number of them.

So forget about what monsters have a better drop rate, quantity over quality is more important. The wiki is right, farming harpies is the way to go. 1 drop per hour if you're efficient. Nekkers in Act 1 if you want to start earlier.
