EDIT: TEST SHOWS THAT BONETRAPS DO NOT WORK. -.-
Hey,
I just remembered a report I got once, about a necromancer raising the fit_for_animation bodyparts that I used as build-mats in my church of the dark depths (evil magic building)
I dont really know how these bodyparts behave, but usually buildmats stay in the building till the building is destroyed, so I figured, why not abuse this ?
Make a building, bone-trap, 1tile, needs X bodyparts/corpses to be build.
Has the reaction: Activate trap, gives a dwarf the interaction to raise friendly corpses.
He will target all the bodyparts in the buildings, and they dont do anything.
Now... a building destroyer shows up, pathfinds to the trap, destroys it, and all animated zombies inside spawn, attacking the building destroyer.
Makes sense, or am I oblivious to any problem with this ? I'll test it anyway, but now it's time for sleep...
EDIT: Oh, and sometimes I am really slow... with the magma and water spawning that stays in workshops, you can easily make a magmatrap and a obsidianizer that work the same way, by spawning the liquid without a container inside the workshop, and then just wait for a building destroyer to trigger it.
EDIT2: While on the topic of traps, I never got my ranged trap comp ammo to "stick in wounds"... would like to use it for syndrome ammo, but I can do workarounds...
Oh, and another form of trap would be a invisible (constantly doing hide-effects) creature with an AoE Aura. Slow Totem, or Fear Totem, Stench Totem, and so on.
