After attacking the crime lord I was in for a nasty surprise as the drunken dwarf became hostile, and calming him down turns out to be extremely difficult if not impossible. There was no warning that this would happen and I didn't think he would be particularly loyal to Hotzenplotz either. Given that most of the unique Lawenilothehl NPCs don't turn hostile when you attack Hotzenplotz, this might be an oversight akin to invisible Khelavaster. Some reliable means to pacify him wouldn't hurt either.

Skriek turning hostile might be an oversight too, although Calm Monster does work on him.
