40d:Vermin

Ignorance: tame olms have value of 1 moneys

'''Vermin''' are small [[creature]]s such as rats, bats, and lizards which are difficult to see. Most maps with a temperature above freezing have hundreds or thousands of vermin. The presence of vermin can be noted if you are particularly observant, as they will occasionally blink into and out of view on the screen. They are mostly harmless.

== Risks ==

Vermin are primarily notable for their ability to accost dwarves, whether by triggering deeply-buried childhood traumas or just by being annoying. Most dwarves will have [[thought]]s related to a type of vermin they really dislike, and will suffer a significant mood penalty any time they spot the vermin they hate. This mood penalty can render content dwarves unhappy, although the penalty can be offset by otherwise good living conditions.

Some vermin will also eat any food in stockpiles they can manage to get a hold on. Food that has been protected in barrels will be immune, but food that is exposed will be nibbled at and will eventually wear out and be destroyed.

== Catching vermin ==

Small [[animal trap]]s are designed specifically to catch and hold vermin. A '''catch a live land animal''' order issued at a [[kennel]] tells a [[trapper]] to seek out and catch a vermin animal inside one of these traps. The animal will then be brought to an animal [[stockpile]].

Vermin can be tamed by anyone with the [[animal training]] labour preference at a kennel. Tame vermin can then be offered for claiming as [[pet]]s on the {{key|z}} Status screen under the Animals submenu. However, tame vermin will only be claimed by those dwarves who admire those vermin.

== Meat group ==

Stray, untamed vermin that are caught in animal traps are edible, and will be eaten live as exotic cuisine by some people whose [[preference]]s swing that way.

People who are [[food|starving]] will also attempt to find and eat vermin, but if they do not have a preference for that vermin as a food type, they will receive a bad [[thought]] from doing so. In a fortress with cats, it may be difficult or impossible for the dwarves to find enough vermin to survive starvation, as even a small number of cats are ruthlessly effective at controlling the vermin population. If they are not tamed, it may be best to just butcher the cats for food.

== Extracts from vermin ==

Certain vermin, such as the fire snake, can be used to make [[extracts]]. At present, most extracts have no actual use in the game.{{version|0.27.169.33c}}

== Eliminating vermin ==

[[Cat]]s are chiefly useful for their ability to hunt down and kill vermin. Cats will wander around the fortress killing vermin. As animals do not presently eat, this is done only for sport.{{version|0.27.169.33b}} This reduces or eliminates the possibility of dwarves receiving bad thoughts for being accosted by vermin—dead vermin do not bother any dwarf—but exposes a risk that a rotting [[rat]] or other larger vermin will release a cloud of [[miasma]] and upset any dwarves who pass through the cloud. Vermin caught and killed in closing doors commonly leave [[blood]] and [[ichor]] behind which, if unchecked, can be tracked all over your fortress by your dwarves and other pets.

Another method of controlling vermin is by building animal traps and periodically catching vermin with trappers to be consumed in some fashion. The trapped vermin may be used for a variety of purposes, including being eaten, tamed, or made into extracts, or can be relocated to a cage so that the trap may be used again.

== List of vermin ==

Most catchable fish are technically considered "vermin" by the game, see the [[fish]] article for a complete list. Many vermin do not show up in [[Calendar|winter]]. [[Extracts]] are presently useless except for trade.{{version|0.27.169.33c}} Vermin with no "value" are not capturable (except, perhaps, by [[elves]]).

40d:Ice

2008-03-10T20:45:10Z

Ignorance:

'''Ice''' is [[water]] that has been frozen by cold temperatures, usually because of [[winter]]. Any water that is [[outside]] will freeze during winter, while it will stay the same if it is [[inside]].

A tile of water will freeze into an '''ice wall''', while creating an '''ice floor''' one [[Z-Axis]] above it. The ice wall will be the same no matter how deep the water is. The floor can be walked on freely, and there doesn't seem to be any kind of thin, breakable ice. The ice wall can be [[mine]]d through, which leaves the above ice floor intact. [[Channel]]ing the ice floor will destroy both the floor and the wall. The ice wall will apparently melt into water of depth 7 [http://www.dwarffortresswiki.net/index.php/Talk:Water] when warmer temperatures arrive. Presumably the ice floor will melt as well, but whether it turns into water or just disappears is unknown at the moment.

Ice can be mined through without causing a [[flood]], making Winter an ideal time to get rid of any [[lake]]s that are in the way.

== Ice as a Stone ==

Ice appears as a light blue stone which can be found by mining through an ice wall. Ice can be used to build [[construction]]s and [[workshops]]. Ice boulders and objects made of ice will melt when exposed to warmer temperatures (such as inside a fortress), giving it rather limited use. Nevertheless, workshops made of ice have a certain novelty to them, and it's even possible to make [[furnace]]s out of ice, as counter-intuitive as that sounds.

The games refers to Ice boulders as "water". It doesn't appear in any stockpile options or the manager, but it does appear under the "stones" section of the [[Stocks]] menu.

== Out of Water ==

As ice takes the place of water, entire water supplies can be completely frozen on colder areas. This can depopulate an entire fortress in just the first winter if they're unprepared. The only way to counter this is to make a water pit inside beforehand, or brew enough drinks. Oddly enough, drinks do not require water to make.
[[category:Map_tiles]]

== Smoothing Ice ==

Smoothed ice walls are called straight ice wall, smoothed ice floors all called level ice floor and engraved ice floors are called sculpted ice floors. Ice walls cannot be engraved.

== Melting Ice ==
It can be very important to be able to extract water from permanently-frozen ice (for instance on cold northern maps) in order to give water to the wounded. This can be done with magma. Dig out a tunnel one z-level below the ice sheet and fill it with magma. The ice on the above z-level will melt. You can see this happening here: http://mkv25.net/dfma/movie-153-meltingwateronglacier

It is also possible to melt ice by collapsing several z-levels of ice wall into a rock reservoir[http://www.bay12games.com/cgi-local/ultimatebb.cgi?ubb=get_topic&f=11&t=000855]:
