各种武器。

本页面所称的武器Weapon,指任何专门用来在战斗中向对手挥舞的物品。在要塞模式,武器可用一块金属条锭*在锻造间打造(包括所有金属武器,连同金属弩,以及25支一组的箭矢),可用一根木头骨头弩匠工坊制作(木制和骨制弩,以及25支一组的木箭,5支一组的骨箭),也可用一块黑曜石加一根木头在手艺工坊制作(仅包括黑曜石短剑*)。

(*大多数非木制武器不需要所谓的“木制把手”,仅有的例外是黑曜石制作的短剑。所有金属武器,包括金属短剑,在生产中不需要任何木料。)

基本信息

自产武器与异族武器

在要塞模式,武器可分为两类:你能生产的武器,和你不能生产的武器。在锻造间武器匠能锻造七种自产武器。另外,也有十四种异族武器,能从外敌士兵手中缴获,也能从商队处购得。(需注意,由于一些漏洞,有几种异族武器在矮人手中实际上是不可用的。)这些异族武器可能会要求你的矮人运用他们不熟悉的技能,无法大批量购买,而且材料和品质参差不齐。和其他武器一样,它们在交易时较为昂贵。如果能得到一件高品质(见下文品质章节)的异族武器,它们还是值得一用的。由于对其他种族来说,这些武器很常见,若你需要与手持这类武器的敌人交战,了解它们的属性便颇为重要。

武器类别

主条目:Attack types

游戏机制上,所有的武器攻击都被分为“刃击”与“钝击”类型。而在实践中,又可更细分为四类:

  • 劈砍
  • 戳刺
  • 锤打
  • 远程

(矮人文明的自产武器,即矮人能自己制造的武器,将首先列出。异族武器,即必须从敌人尸体上缴获或者交易得到的武器,以斜体列在括号中。矮人能用许多种异族武器,但但高品质的异族武器比较稀有。)

劈砍武器

此类武器的作用方式,是将力道集中于其利刃上,以在敌人身上割出创口,或将其肢体、首级完全斩下。当肢体的粗细小于武器的刃长,就很可能被斩断。对于体型不特别巨大,也不着盔甲的敌人来说,劈砍武器的杀伤效率是最高的。但对着甲敌人就没那么有效了,因为盔甲能阻挡切割,将劈砍转化为较弱的钝击伤害。斩断肢体的一个好处在于,被斩下的肢体不再能作为攻击目标,因此矮人就能将攻击集中在更关键的部位。

短剑通常来说,不如战斧有效。尽管归类为“劈砍”武器,对战斗数据的分析显示,短剑也能用来进行戳刺和钝击(后者来自于剑柄尾端)。而在每一种攻击类型上,短剑的效果都不如别的武器,这就使得短剑成了一种“样样都行,样样不精”的武器。不过,在对付身穿重甲的敌人时,相比战斧,短剑偶尔能做出的戳刺攻击或许能让它稍具优势。另外,如果有黑曜石(再加一些多余的木材)的话,不通过常规的金属产业链就能生产一些黑曜石短剑。

锤打武器

又称为“钝器”或“钝击武器”,此类武器的作用方式,是将力道集中于一团巨大的质量之后,通过挥打,在敌人的盔甲上砸出凹陷,击折其下的骨头。由于骨折会造成极度疼痛,活着的、能感觉到痛苦的生物通常会“屈服”(give in)于痛苦,很快昏迷倒地。而对昏迷倒地的敌人的攻击,则总是精准有力地命中头部,常常能造成致命的脑损伤。即便如此,对于无甲敌人,钝器还是不如劈砍武器杀得快。

戳刺武器

此类武器的作用方式,是将力道集中于尖端,从而穿透盔甲,刺伤内部器官。这种武器经常会卡在敌人身体里,导致使用者在攻击之间,不得不花费宝贵的时间把武器重新拔出来。

远程武器

此类武器实际上就是远距离使用的,轻质的戳刺武器。当敌人与使用者近距离交战,使用者就不得不把此类武器当作近战武器使用。十字弩造成钝击武器*的伤害(使用锤手技能),而近战中的弓被视为一种极弱的剑*。

(等效武器的材料与远程武器的材料相同。)


此外还有一种更宽泛的武器类别,即所谓的“训练武器”。训练武器是木制的,在木匠工坊制作。训练用战斧、短矛、短剑可在要塞模式中制造。此类武器造成钝击伤害,但伤害很低,这是由于木材的材料属性很差。尽管在演习中,所有武器都是安全的,训练武器的主要作用是让矮人在有金属工业之前就开始训练。这些武器也可以用在实战演习中(比如殴打被缴械的哥布林等),以延长演习的时间。最后,这些武器也可交由警卫使用,以降低执法行动的伤亡率。

武器技能

Every type of weapon has its own associated 军事 技能. The higher a dwarf is in his skill with a weapon, the better he will be able to use it in combat, connecting hammer blows to more advantageous sweet spots and sending spears right through enemy hearts and lungs with greater accuracy. The higher the weapon skill, the better at fighting the dwarf will be.

Once a dwarf has reached "Great" skill in a certain weapon, they become [weapon] lords for that specific weapon. They are listed as such on the status screen, will love fighting, and will no longer complain about long patrol duties. Weapon skill is trained in fighting enemies in combat, demonstrations, and combat drills, but if you leave your dwarves shield-less, a danger room will train their skill very, very quickly. Note that this does not quite work for marksdwarves - danger rooming ranged weapons increases their melee skill, increasing their hammerdwarf skill, although this may be the point.

Attachment

A dwarf that has used a particular weapon for a long time will grow attached to it, equipping it whenever their uniform allows them to. This is fine if they are wielding a ☼steel mace☼, but a major problem if they are wielding what is meant to be a training weapon (be it a wooden axe or a copper spear). You can avoid this pitfall by not using training weapons and not forging weapons until you have real weaponsmithing underway. These events generate announcements. If a dwarf does become attached, you can easily force him to relinquish the weapon by assigning a 'specific weapon' instead in his equipment view.

In addition, dwarves that reach a certain number or level of kills, or train long enough with a weapon, will name it. This prompts a major announcement. The weapon in question may have no kills associated with it, legendary dwarves occasionally name their weapons while training with them. Once named, the weapon will appear in the artifact list, albeit in blue. It is unknown if named weapons perform better than unnamed weapons. Dwarves may also become attached to shields and name them in the same way.

品质和奇异心绪

The 品质 of a weapon has a significant (and currently poorly understood) impact on its combat performance, as well as its 价值.

模板:DF2014:Item quality/Table

Weaponsmithing is a moodable profession, which means that you can get 神器 weapons. Artifact weapons have a 3x combat bonus and can be made out of a wide range of materials; ordinarily a hippo bone spear is impossible, but a moody dwarf can create one with a stack of hippo bone. Artifact weapons made of totally inappropriate materials are inferior to regular ones made of weapons-grade metal, although the exact balance is still under discussion. As with other moodable skills, a dwarf who creates an artifact using the weaponsmith skill stands a high chance of becoming a legendary weaponsmith.

Weapons as tools

Hunters use crossbows, 樵夫s use 战斧s (wooden training axes worked prior to version 0.43.01), and 矿工s use 鹤嘴锄s. They must be in possession of these items to do their jobs, and it's as simple as that.

Hunters gain marksdwarf skill from hunting, but wood cutters do not gain 矮人斧手 weapon skill from cutting trees. Miners gain 采矿 skill, which is not considered a military skill, but is used as a weapon skill when fighting with a pick. A dwarf using a weapon as a tool will not use the same tool as a military weapon, instead dropping their tool to pick up another for military use.BUG #1451 Dwarves may carry only one weapon as a tool at a time; for example, woodcutters/hunters will drop their axes then go and pick up crossbows every time they begin hunting.

Ammunition

Main article: Ammunition

十字弩s and other ranged weapons require ammunition (in the case of the crossbow, bolts). This ammunition is carried in a 箭筒 in packs of about 25, and when they run out they will switch to using their ranged weapons as crude hammers. It's often a good idea to try to get them to retreat once they run out of ammo — crossbows are meant for shooting, not bashing.

Secondary weapons

Although it sounds like a cool idea, equipping a marksdwarf with a backup short sword "just in case" doesn't often work, as dwarves are just as quick to run up to their foes and start bashing them with a crossbow as they are to draw their swords and do it properly.

"Best" weapon choices

To put it simply, the combat system behind Dwarf Fortress is very complicated. It's not just a question of "What is the weapon with the biggest number?" - no such thing here. If you want technical specifics, that's addressed in the bottom half of this article (and elsewhere), but for now, from both study of the formulae and observed behavior, there are some patterns for what weapons seem to work "best" against certain targets, and what don't, and (basically) why.

Dwarf Fortress combat is rarely "one-shot", nor is it a long process of whittling away a huge pile of "hit points" (which do not exist in DF). Your best tactic is to try to quickly cripple or stun an opponent, so that you can then deliver a killing blow against a (momentarily) defenseless target, and then move on to the next opponent. The recommended weapons are chosen with this in mind.

Superior metal rule

As a general rule, if a weapon slashes or pierces, it wants to be made from a "better" metal than the armor it's trying to penetrate. If it is, it goes through more easily; if it is equal, it has some problems, and if it's inferior, it has some real problems. That does not mean that a copper spear can't hurt a superior-metal-clad target - just understand that the odds drop compared to weapons of equal metal, and, similarly, superior weapons start to ignore armor of inferior metal.

Also, note that this effectively works in steps - copper is weak against bronze/iron targets, but feeble against steel, so this "superior metal order" can be considered when choosing both slashing/piercing weapons and armor.

(Note: In this section, if 2 metals are equivalent to each other, they will be placed together in parentheses for ease of comparison.)

  • , the clear best*
  • (青铜 or ), very respectable, roughly equivalent** to each other
  • , a distant third
  • , a very distant last (included only because silver is listed to make slashing/piercing weapons)
(* There is also 精金, which is late game only, in a different league from the rest. That is not the subject of a "basic" discussion.)
(** There are some "X weapon vs Y armor" situations where iron is slightly better, but a couple where bronze is actually better than iron - but each is a very specific case. "Roughly equivalent" is a good rule of thumb.)

Blunt weapons do not follow this rule, and instead use a "heavier is better" rule. See below.

Ranged attacks (for dwarves, 十字弩s, but also bows and arrows for enemies) are also piercing, and suffer even more from the "superior metal" rule. It can be very disheartening to see all those cheap bolts bounce off their armored targets when it matters most.

vs. unarmored

This includes most wild 动物s, siege-mounts, thieves, kobolds, etc. Leather/bone armor helps against animal attacks, not against metal weapons.

It may also include some semi-megabeasts and 巨兽s, depending on specifics.

  • recommended weapon: any spear 4
  • other choices: any sharp weapon

Most unarmored creatures are biological beings much larger than dwarf, a situation where spear excels at reaching the vitals. Other sharp weapons can easily remove head or limbs, which also stuns the target, which then allows that quick killing blow we are looking for - one two, one two. In theory, all edged weapons follow the "superior metal" rule, but, against unarmored targets, skin and bone will always lose to any edged metal weapon - even silver! Short swords are lighter and so have a little less power behind them, but again, against all but the biggest animals, no one will notice. (However, see "vs. undead", below.)

Blunt weapons can break bones, which stuns the target and allows a killing blow, but removing a limb is obviously better. War hammers break bones more easily than maces, causing pain, though maces archive total pulping blow sooner. However, unless you're facing small enemies even the best blunt weapon is going to lose to the worst sharp weapon.

Crossbows can hit a vital organ, knee or guts if lucky, but otherwise are slow to cripple and may get off only 2-3 shots before melee combat begins. They are, however, excellent for chasing down fleeing targets, making them ideal against various thieves/wildlife.

And the bonus lesson here is... armor your military.

vs. armored

Usually showing up only during a siege or ambush. 品质 has a significant effect, but copper chain pieces have much less stopping power than bronze/iron plate pieces.

  • recommended weapon: steel sword 2
  • other choices: steel pick, any steel sharp weapon, any warhammer or pick

Your typical goblin or human sieges will never have steel. Even when undead have it, the coverage is only partial.

Steel swords have biggest variety of attacks, allowing them to both stab organs and remove limbs. Picks have the velocity of a blunt weapon with the edge of a sharp weapon, giving them extra punch. Functionally, having "superior metal" will make the battle much like removing enemy armor.

(Note also that piercing weapons have a chance to get stuck in an opponent, which can lead to wrestling to get the weapon out, or to apply more punishment.)

Blunt weapons work on flexible chain almost as well as against an unarmored opponent, and can deform solid armor (which is everything "not chain") to land a killing blow. Warhammers are superior to maces in penetrating solid, "non-chain" armor and breaking bones.

Slashing iron or worse weapons really suffer here, and especially so against non-chain targets. It's critical that they be superior metal if you want any chance of them having much reliable effect against heavy armor. A lucky blow can still take a limb, but often slashing blows just do little more than anger the target.

Crossbows suffer doubly from superior metal issues against chain, and it only gets worse against plate 3

vs. 不死族

  • recommended weapon: any mace (silver or steel slightly preferable), iron axe 5
  • other choices: any warhammer

Undead... you can slash a limb and they keep coming. You can pierce their heart and their eyeless sockets don't blink. They don't feel pain, they aren't stunned, they have (almost?) no vital organs - so that leaves pulping them back to the corruption from which they sprung. Maces are superior to war hammers for this job. Silver and steel weigh slightly more than iron/bronze/copper, but they are all very similar here.

However, often the undead are too big for maces or hammers to do much damage or too numerous to rely on slow but final approach - in which case, iron axes do best in creating minimal body parts while still mangling fairly often and successfully downsizing them. Cutting off the head, neck or lower body will always kill, after all.

Often undead will show up armored, and/or with armored living mercenaries, and, from the previous, we know that a mace or hammer is good against that, too (though not so for iron axes).

Only a very lucky crossbow shot will destroy the brain of an undead - and not all are susceptible to that.

vs. others

This category consists of the rare "not like anything else" creature, the type you get when you breach the 洞窟s or magma (or deeper), or once your fortress is large enough to get their attention.

  • recommended weapon: (varies)
  • other choices: any steel axe (depending), crossbow (from behind fortifications), whip

There are many different types here, and no one approach works for all. Some are merely gigantic but (more or less) "normal", but many are non-organic, and most enjoy the "don't feel pain" tag, including 泰坦s, 遗忘猛兽s, 青铜巨像es, Iron man, and hidden fun stuff. Many of these enemies have no internal organs while being huge, weakening the effectiveness of pain and pierce. Some are still flesh and blood, and they're functionally like unarmored wildlife, but some are made from some material that may be very difficult to slash at.* In the worst case of being made of steel, it leaves chipping away at the target until they collapse from cumulative damage, which means either penetrating a LOT of armor (warhammer or ideally whip) or breaking everything (mace). Some few megabeasts are metal (e.g. 青铜巨像), and the "superior metal" rule goes strongly in effect there - use steel sharp weapons for them, though whip would be best if you don't have those.

(* although a forgotten beast made of, for instance, "mud" is laughably easy to kill)

Ranged attacks are useful for taking care of the ones who are unapproachable themselves while being incredibly fragile. And at the very least, you're at less risk when raining down bolts from above, even if it won't do much damage.

Final verdict

Now, all that said, overall, if you had to choose one "least worst" weapon, it would probably have to be... the </u>steel axe</u>. It has no true counters5, no enemy it cannot ever defeat - while spear falls to iron men and mace/hammer falls to big creatures. If you cannot get steel, a second option would be the goblin-made whip, which is still somewhat effective against bronze colossi and big beasts.

Outside that, for edged/piercing weapons (axe, spear, bolts, and sword) against unarmored (and non-"unusual" targets) any metal will be overpowered, easily cutting/chopping/piercing all equally. Soft targets aside, make edged/piercing weapons out of the best metal you can (steel > iron/bronze > copper > silver) for use against armor, if/when you meet that. Crushing weapons (in order: hammer, mace, and crossbow in melee) can be any metal, with silver or steel each slightly preferable. If you want to add megabeasts into the consideration, go with steel to be safe, for any weapon type.

Technical

From here down, there are tables of values pulled from the game code, some technical analyses, a few statistical observations, and some solid and some speculative inferences and conclusions.

Insert obligatory "math warning" here.

Details

  • If you find your dwarves wearing more than one weapon – or any unwanted armor, for that matter – one way to get rid of them is to dump the weapon from their v-i inventory screen. This does not always work, as they might re-equip the item. Another option is to remove any weapons and/or shields listed on their military equip screen. This too does not always work. At least "left-handedness" seems to not pose a problem. If you cancel the work by v-p and selecting a job that needs a tool they will sometimes put it back in the pile. Example: Miners use picks, cancel their mining job and they will put the pick away AFTER you ordered it to be dumped.
  • Using weapons is much more effective than unarmed combat – an untrained swordsdwarf with an weapon can defeat a grand master 摔跤手, provided neither is wearing armor.
    • Larger weapons with more heft tend to do more damage. How damage is calculated is currently not fully understood, and this area begs for more !SCIENCE!.
  • The size for a weapon is its volume in cm3.
  • Attacks of type EDGE will either slice or pierce their target, depending on the contact area and penetration depth, while BLUNT attacks tend to damage internal organs without necessarily causing significant damage to outer layers.
  • The contact area represents the area of contact of the weapon, and the penetration determines how deep the attack goes (and is apparently ignored entirely for BLUNT attacks – indicated by numbers in parentheses). Large contact areas combined with low penetration represent slashing attacks, while small contact areas with high penetration behave as piercing attacks.
  • The velocity seems to adjust the amount of actual force used during the attack (otherwise based on the size of the weapon, the material from which the weapon is made, and the strength of the wielder) - for example, war hammers have a 2x velocity multiplier, presumably to model the fact that the hammer's mass is concentrated at the tip which, when combined with a long handle, permits swinging it harder than a weapon whose mass is evenly distributed (such as a sword).
  • Crossbows can be made of metal, wood, and bone. Metal crossbows are made by a 武器匠 at a forge, while wood and bone crossbows are made by a 弩匠 at a bowyer's workshop. The material of a crossbow does not affect its firing ability, only its melee damage. A dwarf's marksmanship skill is only affected by the core quality of the bow. This may be a consideration when deciding which dwarf you want outfitting your marksdwarves: a legendary bowyer is a better choice than a proficient weaponsmith.
  • Dwarves will never select a pick for a weapon if allowed "individual choice." You must specify picks as part of their uniform, or on the individual equip screen, if you wish to utilize them as weapons.

Foreign weapons

Using any multi-grasp weapon in a single hand (i.e. with a shield in the other hand) gives you a disability to hit - do not equip two-handed swords with a shield, for instance.

In adventurer mode, however, it is possible to wield a two-handed sword, or any multi-grasp weapon, in one hand without penalty (allowing for the simultaneous use of a shield) if your character passes the one-handed check for single-handing a multi-grasp weapon. For example, if you create a human character, and manage to spawn into a world with a "broad body" or a "tall body" in the character description, you will be able to single-hand any multi-grasp weapon (and will be forced to, much like you are forced to single-hand any single-grasp weapon), which allows for the simultaneous, disability-free use of a shield, thus making your damage and defensive capabilities much higher than they would be with a single-grasp weapon and shield. Note that upping Strength to Superior (and eventually Superhuman) will make all attacks more likely to deal extra damage, making cutting off the limbs of your enemies much easier.

Special variations

Some rare entities have their own procedurally generated variations of weapons. Currently, these weapons are produced by copying the default properties of the "base" weapon, and adding an adjective ("bulky", "large-headed", "branching", etc.) or renaming the weapon altogether ("blade", "curved sword"). Dwarves in strange moods which select from all weapons with a certain tag may produce one of these procedurally generated weapons. Since they retain the properties of their base items, these weapons should be as usable as a standard weapon of the base type.

Size

Weapons have a minimum size to use at all, and a minimum size to use one-handed. Adult dwarves vary in size between 33750 and 93750 (average 60000) based on their height and broadness. Unfortunately, this is currently bugged in fortress mode.BUG #0005812 'One-handed' vs. 'two-handed' checks are performed correctly, but 'can wield' vs. 'can't wield' ignores height and broadness modifiers. So dwarves in fortress mode will never equip two-handed swords, great axes, halberds, mauls, or pikes. Other weapons have a minimum wielding size of less than 60000, and are wielded one-handed if the individual dwarf is large enough. See this forum post.

The following table shows approximately how many dwarves should be able to use each weapon one- or two-handed (see this forum post for details), with all fractional numbers being approximate. While there are seven categories each for height and broadness, the number used is chosen randomly from within each category.

Where the size checking bug affects weapon wielding for dwarves, correct approximate figures are given in brackets.

  • Combat information is used internally by the game to determine the combat properties of weapons and armor made from this metal:
    • Density: Used in conjunction with other factors - heavier weapons (higher numbers) hit with more force, light weapons tend to have less penetration. Value shown here is g/cm3, which is the raw value divided by 103
    • Impact yield: Used for blunt-force combat; higher is better. This is the raw value divided by 103 (i.e., kPa).
    • Impact fracture: Used for blunt-force combat; higher is better. This is the raw value divided by 103 (i.e., kPa).
    • Impact elasticity (or strain at yield): Used for blunt-force combat; lower is better. This is the raw value.
    • Shear yield: Used for cutting calculations in combat; higher is better. This is the raw value divided by 103 (i.e., kPa).
    • Shear fracture: Used for cutting calculations in combat; higher is better. This is the raw value divided by 103 (i.e., kPa).
    • Shear elasticity (or strain at yield): Used for cutting calculations in combat; lower is better. This is the raw value.
  • General Term Explanations (from Wikipedia)
    • Yield Strength - The stress at which material strain changes from elastic deformation to plastic deformation, causing it to deform permanently.
    • Fracture Strength - The stress coordinate on the stress-strain curve at the point of rupture.
    • Stress - Force per area = F/A
    • Strain - Deformation of a solid due to stress = Stress/Young's Modulus

Explanation

  • Yield Strength is the amount of stress required to permanently deform (bend) a material (plastic deformation).
  • Fracture Strength is the amount of stress required to permanently break (rupture) a material.
  • Elasticity or Strain at yield is the amount of deformation (bending) that occurs at the yield point.

Implications

Yield strength combined with strain at yield can tell what a material will do under stress (be it from a hammer, axe, or arrow); higher yield means that it takes more stress to deform, while lower strain at yield means that it will deform less when stress is applied.

Combat formulae

Penetration is poorly understood, but most of the rest of combat is fairly well understood.

First, you need to calculate your weapon's momentum.

Melee Weapon Momentum: M = Skill * Size * Str * Vel / (106 * (1 + i_Size/(w_density*w_size) )

  • Dwarf Melee Momentum: M = 0.06 * Str * Vel / (1 + i_Size/(w_density*w_size) )
  • Quick attacks halve melee momentum, wild and heavy attacks multiply it by 1.5
  • Attacking a prone opponent in melee doubles momentum.

Ranged Weapon Momentum: M = (w_density*w_size)/105 * min(105*(SHOOT_FORCE/20)/(w_density*w_size), SHOOT_MAXVEL/10)

  • Bow and Crossbow Momentum: M = (w_density*150)/105 * min(105/(w_density*3), 20)
    • If 20 is smaller because the ammunition is density 1666 or less, M = w_density*3/100 = w_density*0.03
    • If 20 is larger because the ammunition is density 1667 or larger, M = 50
  • Blowgun Momentum: M = (w_density*20)/105 * min(105/(w_density*4), 100)
    • If 100 is smaller because the ammunition is density 250 or less, M = w_density/50 = w_density*0.02
    • If 100 is larger because the ammunition is density 251 or more, M = 5

where:

  • M is the momentum.
  • Skill is a gradual multiplier based on skill level, from 1x base up to 2x at Grand Master.
  • Str is the creature's strength (e.g. 1250 for the average dwarf)
  • Vel is the weapon's velocity modifier if present (e.g. 1.25x, 2x)
  • Size is the average creature size (e.g. 60000 for dwarves)
  • i_Size is the specific creature's size
    • Dwarves range from a minimum size of 33750 to a maximum size of 93750, with an average size of 60000.
  • F is "fatness modifier" (also includes muscle) = i_Size/Size; dwarf with size of 66150 will have F=66150/60000=1.1025
  • w_density is the weapon's material's density for melee weapons, or the ammunition's density for ranged weapons
  • w_size is the weapon's size for melee weapons, or the ammunition's size for ranged weapons
  • SHOOT_FORCE is the ranged weapon's SHOOT_FORCE constant, which is used to determine its maximum momentum.
  • SHOOT_MAXVEL is the ranged weapon's SHOOT_MAXVEL constant, which is used to determine its maximum velocity, where ammo momentum = ammo mass * ammo velocity.

An edged weapon undergoes the following comparison:

M >= (aSY/wSY + (A+1)*aSF/wSF) * (10 + 2*a_quality) / (Sha * w_quality),

where:

  • aSY is the armor's SHEAR_YIELD, which is based on its material
  • wSY is the weapon's SHEAR_YIELD, which is based on its material
  • aSF is the armor's SHEAR_FRACTURE, which is based on its material
  • wSF is the weapon's SHEAR_FRACTURE, which is based on its material
  • A is attack contact area, typically between
  • Sha is weapon material sharpness multiplier (1x for most metals, 1.2x for 神圣金属, 1.5x for 玻璃, 2x for 黑曜石, 10x for 精金 and 0.1x for all other materials)
  • w_quality is weapon 品质 multiplier (1x for normal quality, 1.4x for fine, 2x for masterwork, etc.)
  • a_quality is armor 品质 multiplier

Expressed in the above terms,

  • 0.06 * Str * Vel / (1 + i_Size/(w_density*w_size)) >= (aSY/wSY + (A+1)*aSF/wSF) * (10 + 2*Qa) / (Sha * w_quality)
  • 0.06 * Sha * w_quality * Str * Vel / (1 + i_Size/(w_density*w_size)) >= (aSY/wSY + (A+1)*aSF/wSF) * (10 + 2*a_quality)
  • 0.06 * Sha * w_quality * Str * Vel / ((1 + i_Size/(w_density*w_size)) * (10 + 2*a_quality)) >= aSY/wSY + (A+1)*aSF/wSF

Because Shear Yield and Shear Fracture are always within a power of 10 of each other for actually available materials, but the smallest possible A value is 20 (a blowgun dart, which is smaller than the smallest item of clothing/armor a dwarf can wear), this means that in practice, Shear Fracture is significantly more important than Shear Yield, and you can reliably compare weapons and armor without paying attention to Shear Yield. In both cases, higher is better on both weapons and armor, as is quality. Sharpness only matters to the weapon, and smaller contact area is better for the attacker.

If the test is passed, attack momentum is decreased by some 5% and the layer is considered punctured/severed, and the process continues to the next layer, including working through layers of the defender's body. If the test is failed, the attack becomes blunt for this layer.

If the attack is blunt, either due to starting off blunt or due to failing the above test, it is then subjected to this test:

2 * w_size * wIY > A * a_density

where:

  • a_density is the armor material's density
  • wIY is the weapon's impact yield in MPa (i.e. raw value divided by 106).

Failure means the attack bounces off, meaning denser, larger armor resists blunt attacks better, but larger blunt weapons with larger contact areas and higher impact yields get through armor better. This also means adamantine armor is some of the worst in the game at outright deflecting attacks, due to its poor density, but this is not typically relevant, as impact yields are typically at least 10 times larger than density values for the actual metals available, so this step is routinely passed by most weapons regardless of relative materials.

On success, the following test is applied:

M >= (2*aIF - aIY) * (2 + 0.4*a_quality) * A,

where:

  • aIF is the armor's impact fracture in MPa (i.e. raw value divided by 106)
  • aIY is the armor's impact yield in MPa (i.e. raw value divided by 106).

Note that the armor wants as high impact fracture as possible to make this test fail. The armor also wants low impact yield, although the weapon's impact fracture does not matter, and high quality and high contact area.

On a success, attack momentum is decreased by some 5% and the layer is considered punctured/severed, and the process continues to the next layer, including working through layers of the defender's body. If the attack was edged, it becomes edged again. On a failure, the momentum is multiplied by SHEAR_STRAIN_AT_YIELD/50000 for edged attacks or IMPACT_STRAIN_AT_YIELD/50000 for blunt attacks, then it becomes *permanently* blunt, and is passed on to the next layer. This means most rigid metal armor will reduce blocked attacks by 98%-99%, but elastic armor, such as a mail shirt, has both strain at yield values raised to 50000, so it multiplies by 1 at this step (i.e. does nothing to the momentum, but does still convert it to blunt) regardless of material.

Combat testing

In regards to edged weaponry: 精金 and take first and second place respectively, with the third best material in the game, matched by the 青铜s. Beyond that is , the second worst material, and is the worst weapon material available (and due to the existence of training weapons, not even useful in that regard).

Additionally, with regards to blunt weapons, almost all of the non-adamantine materials perform equally well, with a very slight edge towards steel and silver. Here is the thread with the details: [1].

Keep in mind with how unbelievably complicated this system is nothing should be taken as word of law yet.

Best Better Good Fair Poor Terrible Notes
Armor Adamantine Steel Iron Bronze, Bismuth Bronze Copper
Edged Weapons Adamantine Steel Iron Bronze, Bismuth Bronze Copper Silver For piercing iron armor, copper is better than bronze, but when piercing copper or bronze armor, bronze is better than copper.
Ammunition Steel, Iron, Bronze, Bismuth Bronze, Copper, Silver Adamantine Adamantine bolts deflect off of adamantine armor, but otherwise their performance is on par with bolts made out of other metals.
Blunt Weapons Platinum, Slade Steel, Silver Copper, Bismuth Bronze, Bronze, Iron Adamantine All six standard weapon metals perform nearly identically. Steel has a slightly higher rate of critical wounds, while silver is slightly more likely to penetrate armor. Platinum (only available as 神器 weapons) has twice the density of silver and several other improved properties, making it the best metal for impact weapons, though very limited in production. Adamantine's light weight makes it a terrible choice for blunt weapons, roughly the same as making a weapon out of featherwood or cork.

Cross referencing this table with the table at the top of this section seems to indicate that low densities, high impact fractures, and high shear fractures contribute to the killing power of edged weapons.

Analysis

Testing of weapons (15 dwarves-versus-15 dwarves combat) in the object testing arena shows that the best dwarven-made weapon against unarmored humanoids is the battle axe, while the war hammer performs the best against armored targets. v0.31.12.

Even in 15×(steel armor+silver war hammer) versus 15×(adamantine armor+adamantine battle axe) matches, hammerdwarves won with less than 50% casualties (mostly one-strike kills). However, when the dwarves in question were without armor or only wearing leather/cloth, the result was inverted — axedwarves won with less than 50% casualties. In battles against megabeasts, 6 silver hammerdwarves were barely able to scratch a 青铜巨像 (attacks were glancing away) due to bronze being a better "weapon" material.

This is because silver has the highest solid density of all materials that can regularly be made into weapons by dwarves. Tests show that indeed and (increasingly dense) do increasing amounts of damage, and that war hammers remain the tool of choice, however they can only be produced by a moody dwarf (and a very lucky one at that).

More arena tests are available in the Military testing article.

Bugs

  • Equipping weapons/armor on military is erratic. This is likely due to a single piece of weapons/armor being erroneously assigned to multiple dwarves and seems to occur when dwarves are upgrading their equipment or going on raids. Removing and reassigning equipment for all military dwarves can temporarily fix this problem.BUG #535
  • 'One-handed' vs. 'two-handed' checks are performed correctly, but 'can wield' vs. 'can't wield' ignores height and broadness modifiers, so dwarves in Fortress mode cannot equip two-handed swords, great axes, halberds, mauls, or pikes.BUG #5812
