I am planning to kill a forgotten beast who is currently on a mass murder spree under the fortress. It has access to all cavern levels because of the pits, and its flyer ability.
It has a poison dust of which I don't know the exact effects but appears to do more damage by choking on it than the dust itself does. It also appears to heal very quickly. When trying to research the effects of its poison when writing this post, I realized that I haven't really got too much combat reports coming from it. It likely went down the second or, more likely, third cavern level because I haven't really explored those at all yet, other than a couple of accidental breaches when mining to magma. I only explored the first level, I haven't bothered with the other 2 yet.
It is a great killer, as it has been under my fort for less than a year and has killed over 200 creatures in all cavern levels with ease, including a voracious cave crawler, 2 jabberers, 2 giant cave spiders, 2 blind cave ogres, 7 cave crocodiles(which I really wanted for my army
), and many, many trogdolytes and other monsters. (Although not many crundles.)
I have three squads. The first engages with swords and the majority of the squad is legendary in all of their appropriate combat skills. The second is made of marksdwarves and don't have too much experience, although I can probably engineer the cave's layout so that my marksdwarves are completely safe in the fight and will do some pretty good damage to the FB. The last one is made of axedwarves which is a relatively new squad who I will probably not send in the fight.
Which squads should I send in, and how !!FUN!! will that be?
