I am now in possession of orichalcum through non-basilisk means, since after 6 years in game time, the basilisk have still failed to be sheared, any of the 14. My metalworkers appear unable to actually produce anything with it. They simply cancel the forge job if it involves orichalcum. Sadly, that fort has died a FPS death. Too much expanding and junk collecting.
In the next fort, I had an ant soldier somehow get into my tunnels, and get mobbed by the zillions of grave cats keeping my succubi as pets. They failed to do any serious harm, at which point a war tentacle monster passing by proceeded to rip the ant soldier into pieces.
The tentacle slime got all over the floor and walls and the grave cats, which then, all 20+ of them, proceeded to suffocate to death. All of them dead. All of them pets. I somehow survived the tantrum spam. Somehow. I am not sure if Succubi are just tougher minded or if I was lucky, but the worst of it was a tantruming succubi kissing the foot of another and chipping the bone right through its cloth sandal. Some serious lip action there. My hospital was fully up and running so no big deal. On a side note, war trained tentacle monsters are scary. Also, murder all non-fooccubus created animals on arrival, or seal the pets somewhere safe. Tentacle slime kills friend as well as foe.
Also, kind of as a surprise to me, legendary succubus soldiers are killing machines, even if they are lacking some coverage in their armor. I had a trio of them massacre a dwarven siege without taking any damage, despite one of the 3 dwarven blobs being crossbow wielders. Bronze may not stand up to steel, but it is irrelevant if the bronze wearer dodges every single shot and lands every one of their own. I was afraid the armor options would limit the succubus army because they lack coverage of some body parts, and some are covered in leather only, but the +agility of the succubus seems to make it irrelevant.
I guess I am just used to dwarfs being unstoppable because they are all wearing 5+ layers of steel everywhere.
