I'm playing in a terrifying territory with aquifer, and I think drown chambers will be efficient enough because I think there's is no invaders who can survive a drown chamber (even some of them can swim, but they still will drown). the only problem is that if I don't ATOM those bodies, they will become undead. but I do want Goblinite income. so is there anyway I can do to separate goblins and Goblinites?
or can I simply sink them to cavern lake if they won't be able to land when reanimated?
and I'm also considering how to detain as many invaders in the drown chamber as possible, especially when a massive siege. Pressure plate related to downfall bridge can achieve that but it's a little bit buggy. I'm considering a flooding system which can serve as delaying invaders from fort gate as well as rush Goblinites and goblin bodies close to Fort for looting and ATOMing.
Edit: I come up with the idea of fortification, which allows items pass, don't know if it blocks corpse as it blocks creatures when not submerged.

when invaders come, raise Bridge2, make [Door] the only way in, when some invaders in, draw Bridge1 to release water, rush them onto the Grate. when they all in, undraw Bridge3 to drown them. after they all drown, draw Bridge3 to drain the water and low Bridge2 to loot. when finished, open [Grate] and flood again to sink all the bodies to cavern lake or ATOM.
just worried if there is not enough time for looting. So better if it is possible to separate them automatically.
