Editing 40d:Thief

In Fortress mode, a '''thief''' is a disgusting dishonorable creature that can skulk around the map unseen until it moves adjacent to a [[dwarf]], guard [[dog]] or other similar [[animal]], or other helpful creature.  When a thief does move adjacent to such, the game pauses with an  identifying [[announcement]] and moves the game view to include the threat.

There are two types of intelligent thieves: '''[[kobold]] pilferers''' and '''[[goblin]] baby-snatchers''':

:'''Kobold thieves''' can start appearing quite early (first year) and will sneak right past all of your [[trap]]s, only triggering them if they are injured during their escape attempt and happen to fall unconscious. Armed with only a copper dagger, they offer little threat to anyone - an untrained dwarf or dog should be able to take them down, but extreme bad luck is always a possibility in any [[combat]] situation. While they sometimes steal low value items left outside (intentionally or not), there seems to be a mechanism that makes them target other, higher value items inside instead, too.   

:'''Goblin snatchers''' happily run into any kind of trap. Armed with an iron dagger they should be approached with a little bit more caution, but any average soldier should take them down unharmed. When they get their hands on one of your beloved(?) children, they will stuff them in a bag they carry with them for that purpose.  (Needless to say, this creates a very [[thought|bad thought]] in the parents of the lost child.)  The child is considered part of the snatcher's inventory -- in particular, if the goblin is caught in a cage trap, the child will be caught with him.  Left in this condition for too long, the child may go insane.

:If caged by a trap, the zooming for either may only reveal a flashing [[cage]], a "'''‼'''".  

Both kinds will usually come in small groups of about 1 to 4 individuals. They try to escape once detected and only fight when cornered. Their ability to sneak into your fortress is not to be underestimated; locked doors do not slow them down, although similar barriers that are linked to a [[trigger]] (and are closed) will.  They can lurk around the map for quite some time and wait for their opportunity, even when they are already inside your fortress. They may arrive more or less simultaneously with sieges or ambushes, distraction and general turmoil working in their favor. Guarding any entrance with [[restraint|guard animals]] is a safe countermeasure, though. A successful theft of item or child will be announced once the thief leaves the map.

Spotting the thief is winning the battle, but catching and killing them just feels better. A thief armed with only a knife will rarely - but sometimes - injure or even kill an untrained, unarmoured recruit, but typically the thief just gets worked by the dwarf. A typical thief can outrun a "[[Attribute#Agile|very agile]]", unarmoured dwarf, but can only just keep their own against an "extremely agile" unarmoured pursuer.  Sending more than one respondent to cut off any retreat may yield a more satisfying result.

Certain "playful" [[creatures]] will also try to steal items from your hoard, if left open to more general traffic.  These include [[raccoon]]s, which tend to be solitary, and groups of [[rhesus macaque]]s and [[mandrill]]s (which aren't just playful, but downright dangerous).  In addition, [[black bear|bear]]s and [[gnome]]s will try to steal your [[alcohol|booze]] if they can get at it.  None of these animals has any special ability to avoid standard traps or bypass locked doors.
