Watching for awesome.
You did this with your first fort? I've lost count of all my forts, and still haven't managed to muster a real military (mostly because I only just figured out how to run a proper smithing method). After this fort reading, I'm planning to delve deeper with my 8 legendary weapon masters. Goblins got boring when Dumed defeated a vile force of darkness by launching a snatcher into the leader with his hammer.
I remember back when I was starting the fort I was amazed I could keep the dwarves fed. There were some booze shortages, though... And I still run into issues with dwarves not equipping things they should.
Good luck with your invasion. One thing I feel I should add is that clowns almost completely disregard armour. I've seen them chew through masterwork steel with ease, and if the demon is a blob, or anything else capable of only blunt attacks, its tremendous mass can and will smash a dwarf into the opposite side of the hallway with half of his bones broken. Blobs made of flimsy materials like ash murder everyone in close combat, but can be destroyed with 2-3 bolts. And everything is much less powerful if its legs are destroyed, making it fall over.
Also, have you considered moving this to the DF Community Games & Stories board?
Actually I did back when I started it, and I guess it could be a good idea, but I can't see a "move topic" option anywhere... could you help me?
If you are weaponizing mine-carts I suggest this DF thread from the paradox OT forums. http://forum.paradoxplaza.com/forum/showthread.php?390202-Dwarf-Fortress-Main-Thread/page223
Blue Emu did some real work on a mine-cart death machine. See the downside to loading things into a minecart is that it takes time, and you thus have to reload, whereas if you use a fluid like water (can't use magma cuz it is too dense) the mine-cart is loaded instantly. By using impulse ramps to accelerate the mine cart to its terminal velocity, and thus also the water inside of it, he was able to create a weapon that obliterates pretty much anything you put in front of it. It has a range of more than 60 tiles or so, IIRC. It also reloads incredibly quickly, and with the 5 or so barrels his version had it was capable of sustaining a virtually constant flow of water out of the barrel.
It is quite complicated, and takes a lot of resources and an infinite supply of water, but if you have enough water on hand I would strongly suggest you use it.
It's impressive. And powerful. And very, very dwarfy.
However it's huge, complex and requires power. I need to be able to fit my new defences deep underground, and into a fort which was never intended to house anything like that. I also don't understand repeaters. I do have some water I can use, and I might try to design something running on impulse ramps alone, so the only problem would be resupplying water. Since I would only need to fire the cannon occasionally, reloading time isn't a huge issue.
I checked the world in Legends mode to get the long-awaited FB descriptions, and looked around with Legends Viewer. It seems the Legends mode isn't exactly reliable, unless that's because I messed up the past by running the fix/dead-units DFHack command. One thing I noticed was a bronze colossus destroying small clothes and bolts in Wirejade. By melting. Years after its death. And the fortress has never been visited by any bronze colossi.
A recurring topic in the engravings in the fort were a few creatures: the dragon Slakga Jadeglows the Warmth of Gold, two cheetahs - One Trammelappear and Tuco Singleflag, and a leopard called Slibtu Auburnpuzzling. The dragon killed 14 elves from the neighbouring civ, The Water of Youths, and was killed by one of them in 83. One attacked an elf in 33. Tuco and Slibtu haven't done anything besides dying of old age. Why do my dwarves regard this as a memorable event I have no idea. All are depicted settling in the Lavender Hills, the biome in which the fort is situated. I can understand that nothing else has ever happened there, but still...
Anyway, here are the beasts!
Radavi's killcount is broken and shows only 22 dwarves, whereas it caused the deaths of many more. The demise of the Captain of the Guard, Sakzul, is for example misattributed to a beast called Emxa. For the record, Radavi was killed by a tick devil called Fatesank the Skulls-Plagues of Dust.
If anyone wants to use them in the art contest thread, feel free to do it.
I regret to inform everyone there most likely will be no updates at least until mid-July, since I'll be abroad, and far away from DF. Just so you know the thread isn't dead. Huge thanks to everyone who posted here.
