In my new Fort I'm making a ship. I've decided that I want every prison cell to have a way to execute the dwarf if I so choose, or I can recruit and station a dwarf I don’t like to be executed the same way. The idea is since I'm going to conserve space(it is a ship remember, although its gonna be pretty big) each jail cell will only be a few cells big, with a lever outside it. There will be a chain and an open space. If the trap doesn't work (i.e. the prisoner is on the same cell as his chain) I'll pull the lever and redo it. My ideas so far:
1. Crushed: A bridge comes down on the prisoners head. Straightforward I believe.
2. Spiked: A set of spikes(you can place more than one per block right?) is attached to a lever. As I understand the first pull of the lever will bring the spikes down, the second up. I think this is self explanatory.
3. The Monster Pit: One block of the Prison is a bridge that’s retracted, dropping the prisoner into a small pit with some nasty critter.
4. The Drop Pit(1): The prisoner is dropped a z-level by a bridge retracting and is dropped 1 z-level into a 1 block pit of darkness until he wastes away.
5. The Drop Pit(2): The same as above but enough z-levels to mangle the unhappy dwarf, but not kill him.
6. The Drop Pit(3): Another dropping, this time there is a vertical tunnel going all the way to the ocean. If he can swim to shore he won’t be let back on.
7. The Drop Pit(4): This time the prisoner is dropped far enough on a solid surface to kill him.
8. Prison Cell of Drowning: The cell is simply filled with water and the prisoner drowns.
I plan on implementing all of these, and I would like some more ideas. Please give any suggestions, and I will implement them if possible. Please try and conserve space. I can go anywhere from a 1*2 to 2*2, and If its a really good idea I'll make it even bigger.
