A cruel trap made by a human, for a human.

Any weapon in fortress mode can be placed into a weapon trap. However, there are five trap components, or trap weapons, that are specifically for weapon traps (and two also have additional uses). As with any weapon, a total of up to 10 of these can be put in a single weapon trap, creating a true "Indiana Jones" type of threat to beasts of any size, and potentially simply making a fine mince (or paste, depending on the weapons) of lesser creatures. However, trap components lack weapons' enhanced durability and can break after hitting only about 4 invaders (whereas a copper pick could hit thousands), with the exception of upright spike (which takes less than other components to zero wear, depending on material).

In the order they appear on the various menus, they are the enormous corkscrew, the giant axe blade, the large, serrated disc, the menacing spike, and the spiked ball.

All trap component weapons can be made out of metals (by a weaponsmith) or glass (by a glassmaker), with appropriate damage. Three can also be made out of wood by a carpenter (as noted below), which can be useful in getting some heavy weapons traps set up before you have a steady smelting operation going, or if you are short on metal. Each trap component takes one unit of the material that you are using (e.g. Each menacing iron spike will take one bar of iron). Note that although it is not possible to make giant axe blades or serrated disks out of wood, wooden ones can sometimes be bought from the embark screen. This is presumably a bug.

Trap weapons also provide the highest return of any weapon for melting, 120%–150%, compared to 90%–120% for conventional weapons, which can be exploited for generating metal and training weaponsmiths. Trap components are a separate sub-section of a forge menu (where metal mechanisms can also be found), but found within the menus for the various glass types in the glass furnace, or in the main menu of the carpenter's workshop.

Trap Weapons[edit]

Menacing spike[edit]

The menacing spike can be mounted in both traditional weapon traps and upright spike traps, which act quite differently. Its small contact size and high penetration depth makes it a decent choice against enemies with impale-able internal organs.

Menacing spikes can also be made from wood.

Large, serrated disc[edit]

Large, serrated discs deal large amounts of damage, and have a tendency to sever their victims' limbs. While amusing, this can create several hauling tasks for dwarves as they have to move each severed body part to a butcher's shop or refuse pile. Large serrated discs attack three times, giving them a very high damage potential.

Spiked ball[edit]

The spiked ball doesn't deal a blunt attack at all, but it does do three attacks with its spikes. Like the menacing spike, it has only a small contact area, but has a very low penetration depth compared to the menacing spike. They can also be made from wood.

Low penetration depth edged attacks can still break bones with impact damage, just like blunt attacks do. In addition, if an edged weapon is unable to cut the material of the target's armor, its attack is converted to blunt type. Because the small contact area concentrates the force, spiked balls should be more effective against targets in superior armor than either serrated discs or giant axes.

Enormous corkscrew[edit]

Enormous corkscrews can be used as components in traps as well as for screw pumps. As a result, the corkscrews from unneeded screw pumps can be used to make serviceable weapon traps.

The enormous corkscrew performs a deeply penetrating attack with a small contact area, much like the menacing spike. It is currently unknown which of these two trap components is the strongest overall.

Enormous corkscrews can also be made from wood.

Giant axe blade[edit]

The giant axe blade is a very similar weapon to the large, serrated disc, but only strikes once, compared to the disc's three attacks. However, due to its larger size, its single attack is stronger than each of the large, serrated disc's. It is currently unknown which of these two trap components is the strongest overall.

However, if the variables behave like those of the wieldable weapons, size determines mass (along with material density) and mass determines impact (BLUNT) damage. An edged weapon, like the giant axe, only deals this type of damage when it is unable to penetrate armor, or if the target is large compared to its penetration depth.

This suggests that a steel serrated disc's multiple attacks will outweigh the giant axe blade's somewhat larger size in most cases. If only inferior materials are available, the giant axe might be better at hurting armored targets, but the disc's three attacks probably still outweigh this advantage.

Forging and Melting[edit]

Giant axe blades[edit]

  • Metal giant axe blades cost one metal bar to forge, or five adamantine wafers.
  • When a non-adamantine metal giant axe blade is melted down, it will return 1.5 metal bars, for an efficiency of 150%.
  • When an adamantine giant axe blade is melted down, it will produce 1.5 wafers, for an efficiency of 30%.

Enormous corkscrew[edit]

  • Metal enormous corkscrews cost one metal bar to forge, or five adamantine wafers.
  • When a non-adamantine metal enormous corkscrews is melted down, it will return 1.5 metal bars, for an efficiency of 150%.
  • When an adamantine enormous corkscrew is melted down, it will produce 1.5 wafers, for an efficiency of 30%.

Spiked ball[edit]

  • Metal spiked balls cost one metal bar to forge, or four adamantine wafers.
  • When a non-adamantine metal spiked ball is melted down, it will return 1.2 metal bars, for an efficiency of 120%.
  • When an adamantine spiked ball is melted down, it will produce 1.2 wafers, for an efficiency of 30%

Large, serrated disc[edit]

  • Metal serrated discs cost one metal bar to forge, or four adamantine wafers.
  • When a non-adamantine metal serrated disc is melted down, it will return 1.2 metal bars, for an efficiency of 120%.
  • When an adamantine serrated disc is melted down, it will produce 1.2 wafers, for an efficiency of 30%

Menacing spike[edit]

  • Metal menacing spikes cost one metal bar to forge, or five adamantine wafers.
  • When a non-adamantine metal menacing spike is melted down, it will return 1.5 metal bars, for an efficiency of 150%.
  • When an adamantine menacing spike is melted down, it will produce 1.5 wafers, for an efficiency of 30%.
