Your best bet for getting magma is probably with the good old pumpstack. If you make the inlet start several layers down in the magma sea rather than the top, it'll give you a constant flow of magma. More towers = more instant magma, of course.
Flooding the map with said magma, iiis tricky. You'll want to design each tower with screwpumps at the second-lowest level (drawing from the lowest internal level) pumping outwards to get it spewing at a decent rate. If you just want one final gasp of "FUCK YOU AAAAALLL!!!!", then that's enough. For something more permanent, you'll need to wall off the map edge as close as you can get to it. I'd also suggest making the bottom of one of the towers just a set of trapdoors that drop into one of the central fortress areas with enough of the fun red stuff to flood the place. Nothing says "screw you all; we're going to hell!" quite like flooding your own home with magma.
If you need help with power for the screwpumps, I have one or two ideas that might do the trick.
Thanks for your help, though I'm not quite sure I want pumps going all the way down to the magma sea. That's about a hundred z-levels down, though to be fair, there -are- about 80 layers in it. I
may have gone a little overboard with the advanced world generation. >.>
I'm thinking about using the magma provided by the volcano I'm on to drain off a fair share to each tower. It'll refill itself, and I'm already using it for my metal industry, so it's a convenient resource. It will, however, be really slow to fill the towers unless I can figure out a way to get magma from it at a higher rate. Maybe dig into it from multiple levels at once, though that could of course drain it faster than it can replenish itself. I could certainly use practical ideas for getting the magma reserve, though this project will take at least twelve years to complete, and most likely more than that.
As for the towers themselves, I'm thinking of making them probably 20-30 z levels high, but give them a large volume. They'll have to be pretty big to cover the embark area (8x10). Anyway, I don't know much about pumps, or magma pressurization, but I do know that I want it to maximize the rate at which magma is pumped out of the top. It needs to be a massive explosion of magma that destroys everything in minutes, and preferably seconds (likely also killing my computer, but eh. Someone's bound to have a computer that can run it, and I can always upload the save just before turning it on).
I also had the idea to make a floor at the output level that covers or mostly covers the embark site. I'm not sure if I want there to be holes in the floor so that there can be a magmafall onto the top of the fortress, or not. Either way is bound to have magma spilling over the edges which sounds really cool. Does anyone have any ideas for this?
I'm a little iffy on the flooding the fortress part, though. I picture this as either the last dwarf alive will win, or the fortress will make a neat home for the clowns that come to visit. Dorfy hell-holes also suit clowns rather nicely.
As for the technical parts of putting this together, ANY help you can give me would be greatly appreciated. And rewarded with
imaginary cookies.
It's a shame the previous Project Armok fell through, yours looks cool, though.
Do you mean Boatmurdered? Or is there another attempt at this that wasn't completed?
It was a project with the same name with a slightly different goal. He wanted to make a randomized homicidal AI-ish mechanical fortress with various terrible ways to die. I think, it's been near 6 months since I last heard anything but a "I'll get to it at some point" though.
Sounds more like GlaDOS than Armok to me. *Shrug*.
