Dear Sistren/Brethren in Armok,


Recently I've been trying to make my fortress out of a volcano.

My plan was to throw water on the lava, so I could form a layer that the dwarves could then excavate, smooth and subsequently engrave.
So I threw some buckets of water on some squares of lava and it didn't work. Maybe the obsidian sank down into the crater?
Is my idea of casting a fortress out of a volcano at all possible? Should I use more water? Or would the obsidian sink down regardless?

Answers on a postcard.


Yours Truly, Drax.

If you're doing a bucket obsidianizing, you'll have to do it from higher up. Emptying buckets right above magma doesn't works, you'll have to be a z higher for water to come out to actually impact magma.

Casting a fortress into a volcano, or even pumping the magma out of volcano and building above surface dark tower works :D

Oh, and if it's not connected to anything, structurally, and you have cave-in enabled, it'll drop. If you tries it right above semi-molten rock, it'll destroy anything that touches it. I think.

I'm doing it with buckets from one Z-level up, and it seems to be working.
