So I just killed my first FB...

... apparently. Hell if I know. I was looking at my graveyard and noticed the corpse of - not one - but two forgotten beasts.

Well that wasn't what I was expecting!

So what are your stories of killing FBs?

(Also, I just killed my 3rd, mostly just using a single fisher dwarf. You'd think the FB would be immune to its own cloud of FB boiling extract, but apparently not?).
