mzprox: Somewhy the nekkers stopped respawning there for me. Anyway I reloaded an earlier save and tried farming in the nekker cave in act 1. Killed 40 nekkers and got 4 lesser mutagens nothing else, so the problem is not with being in act 2 or with harpies, but for some reason th mutagen drop is not as it used to be. Very dissapointing, I think I won't even continue my game, I have already finished it twice, this third run I was interested how big armor I can get, but after this nerf I can't get more mutagens..
:( :( :(
Got me curious about this. I am not calling you out or anything, but I find it hard to believe they changed this. We'll see when I start run number 5 in a day or two. :)
One thing you could do is try using the "Side Effect" ability to generate them. You would need to put a point in Alchemy ability to get there, but that would also mean really devastating bombs.
