Usual agressors are dealt with axe and crossbow.
But for some kind of "salt blob" I'd like to have cave-in trap, preferrably automated.
Is there some known design to start from?
I have in mind a simple design to automate cave-in like this:
* some long tunnel (long - to have time), like this
Z0:
~WWWWWWWW
WXp______ fort
_WWWWWWWW
Z+1:

W - wall
X - door
p - plate
_ - floor
~ - water
. - open space
# - floor grate
I - support
* some (constructed) and digged out walls right above that tunnel, holding on the support.
* door, closing some small water basin with a plate behind the door tuned for small water level (2/7?).
I see it this way:
a) titan opens (or destroys) the door, water will flow and press the plate;
b) the plate brakes the support;
c) walls fall onto the tunnel and kill everyone;
d) dwarves clean everything and rebuild walls, support, doors, the plate and refill the basin with water somehow (no problem)
e) go to start
Are there any caveats?
Will the plate work? How long should be the tunnel? Will it work on ANY titan? Can flyers, or gas titans, or trapavoid or somebody somehow avoid the trap?
