..and a dwarf died after punching a capybara and then fell down the stairs of my fort? rotted and poured miasma out..
Yeah, they fall down the stairs like that because they lose conciousness. Staircases are treated like empty space by KO'd things. I usually split my stair at z-1, just by 10 tiles or so, which lets you put in a guardroom and makes passing out while fleeing from hostiles into the fort less lethal.
This is one of the factors speaking against single central master stair designs for forts. I once had a syndrome hit, something minor with dizziness and fits of unconsciousness, something like 90 dwarves fell to their deaths.
Well this looks easily weaponisable...
If it's weaponisable, I apparently am immune to this weapon.
I always watch the conversations about this with confusion, as I've never had a dwarf so much as stub their toe due to staircases. On one occasion two Urist McMothers gave birth on the stairs, which I have been told would mean that the baby would fall to the bottom, but it was fine. Since then the Outpost Liaison gave birth on the stairs, and her baby was fine too. I've had an attack of bats on the stairs. Urist Mcfighters would attack and either hit or miss the bats, and never fall. A fighter was injured on the stairs, but he didn't fall down the stairs either. A tired dorf fell asleep in the staircase. He eventually woke up and went and got a beer, having had no problems. I've even managed to collapse part of a staircase in a mistaken attempt at remodelling. There was dust everywhere. Two children were killed when a storeroom full of wood fell on them. And no one, not even those dorfs unconcious on the staircase, fell even a single flight. A fire was lit due to an unexpected FB. Even though there were burning dorfs, kittens, and socks travelling up and down the stairs, they never tripped and fell down the stairs, although one dorf did burn to death on the stairs. I have experimented with Hatch covers, as someone said this would have effect. Dorfs are all still fine.
Am I doing something wrong?
