Bane Of The Myconoids Quest
This "quest" involves murdering away at the sanced Fungal Forest residents until they grew tired of you and Psilocybin tries to bribe you away with a bag of gems containing one (or more?) perfect gem.
As time progresses and you persist in killing them, the myconoids will grow more and more dangerous, starting to use gas attacks and other abilities like toss, that were not previously used.
Having completed this quest will net you Bane Of The Myconoids Insignia, and any further entry into Fungal Forest will draw a lot of attention towards the entire group, so it is best to let your leader know immediately you are not welcome in there.
