-.- why do you want/need mist
you could try cutting the fall up with ledges like soo:
v<<<waterfall
v
_v
v_
_v
anyways. BE FOREWARNED: you know where i dug that really deep pit under the bridge? down a few levels and a little bit due south is an isolated magma chamber. magma man kicked my ass.
I think mist gives the happy thought, and a falling column doesnt make any mist. i tried the ledge approach but it makes water puddle out around the area. not dangerous I think but it's muddy. I'm pretty sure an up/down stairway is the best way, as I recall from my early disasters it makes mist but doesnt cause any puddles (except at the bottom). Gaunt feel free to go before me I am gonna be occupied another couple days with some projects I wanna perfect before I start my term in office.
which brings up a question. using "fluid logic" I want a floodgate/drainage system that will release exactly 7n units of water into a chamber at the pull of a lever, then reset and refill so that next time I pull the lever the same thing happens again. this is for farm irrigation. also, a drowning chamber that triggers when an enemy/animal steps on it, fills with water for a few minutes, then flushes the corpse to a grate by the butcher which I will open at my convenience. or if it's non-drownable, I'll use it for bow practice. of course the chamber should reset automatically. I was thinking of building my trade depot inside one of these. don't know if elves can drown? maybe some spikes at the end would seal the deal. ooo can I make a bloody waterfall?
