Revision as of 08:50, 29 January 2012

This article is about an older version of DF.

Mass pitting refers to pitting many caged creatures at one time without having to build each cage and link it to a lever. This allows you to recycle many cages quickly, freeing them up for reuse in cage traps in minimal time.

Mass Pitting System

Also called the Mass Cage Recycling System.

Here's a simple design that keeps you from having to build cages before releasing hostile creatures from them. This is safe for most hostiles, but see warnings below.

Building

  1. Dig out a room and another room of at least the same size directly below it.
  2. In the upper room channel out 6 openings into the lower room which are spaced exactly 2 tiles away from each other.
  3. Build floor hatches and place them over all of the openings.
  4. Place one big animal stockpile over the room such that every tile in the stockpile is adjacent (orthogonally and diagonally) to one of the hatches. Disable empty cages on the stockpile.
  5. Create one large pit zone that covers all of the openings such that all of them are part of the same pit zone. This is critical to prevent hostiles from being led around and spooking your civilians.
  6. Disable all other animal stockpiles except for one empty-cage-only stockpile somewhere.
  7. See The Pit below for some suggestions on what to drop your invaders into.

The top room should end up looking like this:

= = = = = = = = =
= ¢ = = ¢ = = ¢ =
= = = = = = = = =
= = = = = = = = =
= ¢ = = ¢ = = ¢ =
= = = = = = = = =
= is the stockpile
¢ is a hatch cover

The bottom room can look like whatever you want as long as all of the openings you channeled out lead into it from the ceiling.

Obviously you can scale up the top part with more or fewer hatch openings to get larger or smaller stockpile areas, but with six hatches you can empty out 48 cages very quickly, without spooking dwarves, which is enough for many people.

Variations of this design exist, but they all use the same basic principle, that is, all hostiles must be no more than one tile away from a suitable pit. Dwarves must not be ordered to haul the hostile across any distance or else they will become startled and release the dangerous creature.

Use

Warning!

"Thief" type creatures, flyers, or large creatures like titans will escape using this system. If in doubt, build the cage manually or have sufficient military hanging around the top stockpile area.


Before pitting your captives, you may wish to disarm them -- depending on what you've built for them to fall into.

Now, wait for the stockpile above to fill and assign creatures to the pit all in one shot. Being pitted through the hatches will keep dwarves from being spooked by hostile creatures below and with all cages directly adjacent to pits creatures can be dumped in instantly without having to be led around.

A mass of dwarves will pile into the room, pit the creatures at the about same time, and haul the empty cages off to your empty cage stockpile. The poor pathetic creatures they pitted will then be left to the mercy of whatever is at the bottom of the pits.

The Pit

After your dwarves have dumped out the cages the inhabitants will be dropped into the room below. Here you can find some suggestions on it's construction:

Drowning chamber

Fill up the room below with water and watch as the invaders drown. Requires only some buckets and a water source. May be difficult or troublesome to recover anything dropped into the waters below.

Lava Pool

Alternatively you can fill the room with magma and watch as the hostiles are instantly incinerated! Requires an aqueduct and/or magma safe materials.

Empty Room

Leaving the room down below empty has it's benefits. When your melee military has nothing better to do then beating unarmed goblins will train fighting skills quickly. Be sure to haul off corpses before miasma begins forming =)

Fortifications

Marksdwarf training room

By lining the pit room with fortifications you are able to safely train your marksdwarves. This provides a feasible and quick alternative to the slow process of using archery targets. By ordering your military to use bone bolts and leaving your hostiles fully armored even a small group of goblins will live to be used as target practice for months. Miasma produced during this time may give dwarves unhappy thoughts. To avoid this stagger fortifications with solid walls in such a way that diagonal gaps are between you and the rot.

Remember that goblin marksmen will still be able to shoot through fortifications if they are armed sufficiently. To avoid this exclude or disarm them.
