Title: The Best Material for War Hammers Science (50.07)
Post by: Panando on March 05, 2023, 10:00:27 am
There is the age old debate of what is the best material for war hammers? Unfortunately, most tests have far too few samples to be able to have any confidence that the ranking is anything more than luck. Though there has been some good and recent mechanical analysis (https://www.reddit.com/r/dwarffortress/comments/o7llyz/density_has_no_effect_on_blunt_weapons/) which indicates density should matter only a tiny bit.

So I decided to design a new test:

Test Design:

Results

500 samples. Number of hammer bashes required to strike down the ironclad Goblin:
(The lower bound and upper bound are for the 95% confidence interval for the mean)

Code: [Select]
| weapon              | mean  | stdev | confidence_level | margin_of_error | lower_bound | upper_bound |
|---------------------|-------|-------|------------------|-----------------|-------------|-------------|
| platinum war hammer | 16.80 | 9.81  | 0.95             | 0.86            | 15.94       | 17.66       |
| steel war hammer    | 17.19 | 9.53  | 0.95             | 0.84            | 16.35       | 18.02       |
| copper war hammer   | 18.14 | 10.18 | 0.95             | 0.89            | 17.25       | 19.03       |
| lead war hammer     | 18.37 | 9.90  | 0.95             | 0.87            | 17.50       | 19.24       |
| silver war hammer   | 18.39 | 9.53  | 0.95             | 0.84            | 17.55       | 19.22       |

The performance of all the different materials was extremely close, with the worst performer, the Silver War Hammer, requiring on average only 9% more bashes to destroy the Goblin than the best performer, the Platinum War Hammer.

Looking at the 95% confidence intervals we really can't conclude whether Copper or Silver performs better because of the near total overlap of the confidence intervals, nor whether Steel or Platinum performs better, however there is a reasonable possibility that Steel and Platinum outperform Silver.

One reason I chose to add lead (instead of iron) is because the material properties of lead are truly abysmal for weapons, being far worse than weapon grade materials. This did not seem to matter in the slightest.

This test helps to demonstrate, yet again, just how close the performance of different kinds of dense metal is for war hammers.

Quick Tests

I'm also going to add some quick tests, involving only 100 fights per weapon per test instead of 500. A small number of samples can help to identify trends if they are very strong. Also it will help to demonstrate my point about the importance of large sample sizes.

Dwarves with max physical stats, legendary combat skills:

Code: [Select]
| weapon              | mean  | stdev | confidence_level | margin_of_error | lower_bound | upper_bound |
|---------------------|-------|-------|------------------|-----------------|-------------|-------------|
| steel war hammer    | 12.66 | 7.64  | 0.95             | 1.50            | 11.16       | 14.16       |
| platinum war hammer | 13.13 | 8.16  | 0.95             | 1.61            | 11.52       | 14.74       |
| lead war hammer     | 13.76 | 7.43  | 0.95             | 1.46            | 12.30       | 15.22       |
| copper war hammer   | 14.58 | 8.04  | 0.95             | 1.58            | 13.00       | 16.16       |
| silver war hammer   | 15.53 | 7.18  | 0.95             | 1.41            | 14.12       | 16.94       |

Dwarves with max physical stats, legendary combat skills, both Dwarves and Goblins 25% bigger than average

Code: [Select]
| weapon              | mean  | stdev | confidence_level | margin_of_error | lower_bound | upper_bound |
|---------------------|-------|-------|------------------|-----------------|-------------|-------------|
| silver war hammer   | 13.97 | 7.75  | 0.95             | 1.39            | 12.58       | 15.35       |
| platinum war hammer | 14.76 | 8.35  | 0.95             | 1.49            | 13.26       | 16.25       |
| copper war hammer   | 15.07 | 8.49  | 0.95             | 1.52            | 13.55       | 16.59       |
| lead war hammer     | 15.13 | 8.11  | 0.95             | 1.45            | 13.67       | 16.58       |
| steel war hammer    | 16.07 | 7.78  | 0.95             | 1.39            | 14.67       | 17.46       |

Dwarves with feeble (35% of max) physical stats, lvl1 skills:

Code: [Select]
| weapon              | mean  | stdev | confidence_level | margin_of_error | lower_bound | upper_bound |
|---------------------|-------|-------|------------------|-----------------|-------------|-------------|
| steel war hammer    | 84.52 | 45.58 | 0.95             | 8.93            | 75.59       | 93.45       |
| silver war hammer   | 91.08 | 48.84 | 0.95             | 9.57            | 81.51       | 100.65      |
| platinum war hammer | 92.22 | 51.91 | 0.95             | 10.17           | 82.05       | 102.39      |
| lead war hammer     | 93.33 | 44.34 | 0.95             | 8.69            | 84.64       | 102.02      |
| copper war hammer   | 97.26 | 42.78 | 0.95             | 8.38            | 88.88       | 105.64      |

Compare with the 100% physical high skill dwarves: these dwarves took 6.7x longer to kill the Goblin. (Note: the same weak dwarves armed with Steel Picks would have no trouble striking down the ironclad goblins in about 15 hits)
In this test the weak dwarves had trouble killing the Goblin before passing out from exhaustion, some would pass out from exhaustion multiple times, this made the tests take *much* longer to run to conclusion.

Number of times passed out from exhaustion:
Code: [Select]
| Weapon   | mean | stdev | 95% CI      |
|----------|------|-------|-------------|
| Steel    | 1.05 | 0.95  | [0.63,1.47] |
| Lead     | 1.25 | 1.08  | [0.78,1.72] |
| Silver   | 1.37 | 1.26  | [0.82,1.92] |
| Copper   | 1.4  | 1.35  | [0.81,1.99] |
| Platinum | 1.56 | 1.27  | [1.00,2.12] |

While the platinum warhammer users did pass out from exhaustion the most, there is extreme overlap within the confidence intervals, and the platinum war hammer is roughly twice as heavy, if there was a dramatic effect it should be more obvious.

Summary of quick tests

You may have noticed the rankings jumped around wildly, like Silver and Steel totally swapped places between the two "peak physical" tests where the only thing changed was making everyone 25% bigger. This is very likely not bceause Silver performs better against larger targets, but because the sample size is much too small to draw conclusions on which material is better, the only thing being tested is who got luckiest. However the point of these tests was mainly to root out if there's any really strong effect, like weak dwarves totally sucking with platinum warhammers or large beastly strong dwarves being murder machines with platinum warhammers. No statistically significant effect was detected.

Conclusion

The Null Hypothesis that "It doesn't matter what dense metal war hammers is made from" holds up pretty well in this testing. There is no strong statistical evidence for any dense metal being better than another for striking down ironclad goblins.

However there is statistically weak evidence for Platinum and Steel being superior, a conclusion that would be supported by prior, albeit weaker, testing and some theoretical analysis based on accepted combat formulas.

As a note: in 50.07 bludgeoning weapons perform abysmally compared with steel edged weapons unless you are fighting fully steel clad dwarves from a rival dwarven civilization. If you are trying to optimize artifact weapon creation for effectiveness (rather than value), you should ALWAYS try to have the dwarf use steel rather than platinum, if the outcome is an edged weapon the result will be an extremely good weapon, but if the result is a bludgeoning weapon it won't be measurably worse as steel than if it had been made of platinum.

You are truly a scholar of dwarven science.

These posts should be bound in a quire and copied, so that we can read them and ponder.

Thanks Panando!

I found it a little surprising that copper did as well as it did.

Divine metal could also be tested, but it probably comes out being the same as any other metal.

Honestly, bothering to test adamantine again for some hard numbers, likely wouldn't be a bad idea either. You know, just to verify theres at least one metal you shouldn't want to forge your warhammers out of.

I'm not surprised that copper did as well as it did. For the most part the momentum is the same (a heavier weapon hits with less velocity) and it's the momentum that for the most part does the damage. This is also seen with morningstars often performing very similar to maces (excluding some special cases) because the morningstar only has a low amount of pierce, so for the most part it's just dumping a pile of momentum onto a body part and twisting spines and stuff.

Worth testing. I just did a quick test (96 samples) with various materials, peak physical highly skilled dwarves:

Code: [Select]
| weapon                   | mean  | stdev | confidence_level | margin_of_error | lower_bound | upper_bound |
|--------------------------|-------|-------|------------------|-----------------|-------------|-------------|
| silver war hammer        | 14.07 | 8.57  | 0.95             | 1.72            | 12.36       | 15.79       |
| shining metal war hammer | 16.29 | 8.17  | 0.95             | 1.64            | 14.66       | 17.93       |
| wagon wooden war hammer  | 21.92 | 9.57  | 0.95             | 1.91            | 20.00       | 23.83       |
| adamantine war hammer    | 38.94 | 14.90 | 0.95             | 2.98            | 35.96       | 41.92       |

Due to the low number of samples I wouldn't put too much weight on silver out-performing "shining metal" (but it most likely does), but it's certainly safe to assume divine metal war hammers are not amazing and may well be worse than common metal war hammers.

As expected adamantine does badly. TBH the wood war hammer (also representing bone) did better than I would have expected, you still wouldn't want to issue a military dwarf a bone artifact war hammer but I was expecting it to do worse.

Divine metal's significantly worse than normal metal, in the sense that it has difficulty doing anything but bruising vs armor.

Another excellent thread. It's funny how many truisms over the years that have been build around DF are dubious at best, if not flat out wrong.

Generally popular wisdom is broadly correct. Like while you get some people who will insist that silver is the best material for war hammers, you also get the prevailing viewpoint that material doesn't really matter.

There's only one very wrong truism I've uncovered: and that is the best weapon vs undead. Masterwork steel edged weapons (pick, battle axe and short sword - not the spear) strike down and mangle undead dramatically faster than blunt weapons, and although they produce more parts that get renaimated, those parts are trivial to strike down (basically if the limb could be slashed off, it can also be mangled in one hit, since the requirement for both is basically "do catastrophic damage to every layer"). Striking down a zombie in 5 hits, then striking down the 3 appendages which got cut off in 1 hit per piece, is much faster than taking 30 hits with a war hammer to mangle the zombie in one piece. So blunt weapons theorycraft well vs undead, but their performance is just so abysmal that the theorycrafting doesn't stand up to testing.

The belief in blunt weapons being best vs undead probably came from early versions of undead which were extremely particular about under which conditions they would sit down and shut up and IIRC small severed parts could be extremely hard to strike down, unlike now when they get easily struck down in one slash.

I gotta say I've been very disappointed with platinum warhammers.
They especially underperform for weak dwarfs and against unarmored targets. Although I haven't done any !science!
I have been using them extensively since I figured out you can make them consistently via work order.
I was making platinum crossbows as well for that extra bit of oomph (because we all know crossbows are melee weapons in DF) but again see no real benefit, especially for the extra weight.
Interesting that the conventional wisdom on silver is wrong, and I've never really seen any benefit to it in practice.
Back to good old steel it is.

Spoiler: Slightly off topic: (click to show/hide)

On topic:
Looking at the results of the quick tests, there seem to be a drop in warhammer effectiveness against bigger targets. Would it be possible to test:

1) Whether that is true or just a result of a small sample size

2) If it is true, how does the effectiveness change in relation to target's size. Idealy target size should range from smaller than a dwarf (say a kobold) to way larger (forgotten beast/titan).

3) If target size affect warhammer effectiveness, does it also affect other weapons' effectiveness?

There was a significant boost to larger creatures' ability to absorb blunt force relatively early on in 4X.XX. I don't remember which specific update that was, but it was in the notes somewhere.

Edit: Wait, it might have been their resistance to force transmission that got a boost. So giants wouldn't get shattered shoulders from being punched in the upper arm anymore.

Honestly, bothering to test adamantine again for some hard numbers, likely wouldn't be a bad idea either. You know, just to verify theres at least one metal you shouldn't want to forge your warhammers out of.
Could a dwarf even pick up one made of slade?  I'm pretty sure short of modding that this would have to be an artifact.

Honestly, the only real surprise here (although it is great to have actual objective data now) is they run pretty close to each other in quality and (surprisingly) silver is the worst.  I've always made my earliest hammers out of silver because I like imagining dwarves bashing people's brains out with Maxwell's Silver Hammer.  Apparently I should have been using copper (or my usual early game standard bronze).  ETA:  I just noticed you said the overlapping confidence intervals mean they're basically a wash, with one of them possibly being nearly microscopically better.  So I can stick with silver for cheap hammers I suppose.

I sometimes use bismuth bronze, too, no real reason why, I just like it.  And what else are you going to do with bismuthinite?  I'm pretty sure they'd be nearly identical other than dwarf preferences for weapon purposes.

Without going to any more effort, what is your opinion on bronze?  I usually use it for (at least mediocre) early game furniture, weapons, and mostly picks and axes, reserving the dross metals for blunt force weapons like hammers (which appears to have marginal advantages to using more valuable metals in as I suspected).  I make exceptions for reanimating/thralling biomes where you really don't want to cut undead into multiple pieces if you can avoid that.

Considering how dangerous those critters are, it's probably worth the added investment in better materials for even a slight advantage.
Generally popular wisdom is broadly correct. Like while you get some people who will insist that silver is the best material for war hammers, you also get the prevailing viewpoint that material doesn't really matter.

So blunt weapons theorycraft well vs undead, but their performance is just so abysmal that the theorycrafting doesn't stand up to testing.
"Best" is pretty situational.  Except in the most terrifying of biomes you are rarely showing up immediately facing an existential threat.  So "best" may just mean you have nothing but silver.  Generally even the resource-sparse embarks have stuff like tetrahedrite lying around.

I also almost always embark with cassiterite and tetrahedrite to start up bronze production immediately (and if it is safe enough to take some extra time do it via bars instead of directly from ore in order to get some extra silver out of it).  I usually don't even bring a pick and the only high ticket item is the axe I need to cut down the first tree.

So almost all my early items are either wood or bronze.  I also start with clinodev's craftswarves embark, so while my original materials are pretty sub-optimal (but not by comparison to just crossing my fingers and hoping for a metals-rich embark), the quality of the craftsdwarfship somewhat mitigates this.

Bronze is basically iron for most intents and purposes. It's perfectly effective for armor against goblin/human/elf weapons just as iron is, steel is slightly better but it's way more important to at least have iron/bronze armor and steel is just a slight upgrade except in the rare cases of steel weapons (some cavern dwellers, enemy dwarves). In contrast, just like iron, bronze is severely sub-optimal for any edged weapons precisely because edged weapons have trouble cutting through same material armor. It is highly optimal to make edged weapons out of steel, and basically to only use edged weapons made of steel since they severely outperform blunt weapons against nearly everything unless you have modded steel clad enemies.

Bronze is generally very cheap to embark with in ore form, at 1/4 the cost of iron, so can be good for making early armor.

Good point and I do generally try to sell off the early bronze weapons (especially the seriously sub-optimal bronze edged weapons).  The absolute worst is when your starting military squads get attached to crappy weapons.  I try just not to have them on the map, or at the very least, not in military stockpiles.  About the only thing worse is if you aren't paying attention and they get attached to one of those miserable wooden training swords the elves always bring.

I used to let that bug the shit out of me too, but then life is full of disappointment, why should the dwarves be exempt. They can suck it up and deal with it when I take their crappy stuff away to give them masterwork steel. I haven't had a tantrum spiral from it or really anything other than bugs in many versions so as long as you go to reasonable lengths to keep order you should be good(other than what amounted to a civil war that I gave up trying to figure out WTF happened)

So considering the platinum is like twice the weight for little to no gain I'm going to consider it a bad choice and remove it from my work orders (probably not in DFHack just my own, I may suggest it to Myk, but I'll leave it up to him how he wants to handle it). The silver all things considered is still not an awful choice I guess. We're talking war hammers, maces and crossbows only of course. What do all y'all think? I mean you generally have steel or you don't have steel so it isn't like there's a need to conserve it usually. Maybe I will drop the silver down below steel, which the numbers above support (right now the upgrade path goes copper>bronze>bismuth bronze>iron>steel>silver>platinum and the work orders are chained to choose based on what you have to work with) So it'd still make sense to use silver if you don't have steel.

I rarely use platinum for weapons because I think it is one of the best (and rarest) metals for increasing room value, so when I become the Mountainhomes, stuff made of platinum is how I build royal-quality rooms.  That and aluminum.

I make exceptions for when there are specific Legendary dwarves who could make great use of a masterwork-quality weapon.

aluminum is so lightweight, it makes for great cages and other things dwarves will frequently haul

So considering the platinum is like twice the weight for little to no gain I'm going to consider it a bad choice and remove it from my work orders (probably not in DFHack just my own, I may suggest it to Myk, but I'll leave it up to him how he wants to handle it). The silver all things considered is still not an awful choice I guess. We're talking war hammers, maces and crossbows only of course. What do all y'all think? I mean you generally have steel or you don't have steel so it isn't like there's a need to conserve it usually. Maybe I will drop the silver down below steel, which the numbers above support (right now the upgrade path goes copper>bronze>bismuth bronze>iron>steel>silver>platinum and the work orders are chained to choose based on what you have to work with) So it'd still make sense to use silver if you don't have steel.

Well, now that more !SCIENCE! has been done, I can stop worrying about having my elite Hammer Lord squad all carrying around masterwork platinum war hammers and just let them use any old material. Now I can have them all using up those masterwork copper/silver/iron/bronze war hammers my weaponsmiths can churn out like crazy from all the practice they got making menacing spikes and stacks of bolts.

Worth testing. I just did a quick test (96 samples) with various materials, peak physical highly skilled dwarves:

Code: [Select]
| weapon                   | mean  | stdev | confidence_level | margin_of_error | lower_bound | upper_bound |
|--------------------------|-------|-------|------------------|-----------------|-------------|-------------|
| silver war hammer        | 14.07 | 8.57  | 0.95             | 1.72            | 12.36       | 15.79       |
| shining metal war hammer | 16.29 | 8.17  | 0.95             | 1.64            | 14.66       | 17.93       |
| wagon wooden war hammer  | 21.92 | 9.57  | 0.95             | 1.91            | 20.00       | 23.83       |
| adamantine war hammer    | 38.94 | 14.90 | 0.95             | 2.98            | 35.96       | 41.92       |

Hey Panando, I know that we know the differences here are negligible, but I'm curious, is there any chance you're interested in seeing how iron, bronze, and black bronze compare?

Relevant: I just encountered some people the other day who have yet to see accurate data pertaining to a silver vs. iron comparison, and so their default assumption in the absence of any evidence that specifically proves otherwise, is that silver is a categorically superior material for blunt weapons, obviously.

This remains my assumption, and I've read the thread.

And although I never commented at the time, my main point of interest was silver - I've been preferring that since a much older edition, and never examined the assumption. High performance of steel was a big surprise to me - but then that silver/steel order reversed in one of the lower repeat tests. So how much of that order is noise from low sample counts? Or, just how much is DF combat randomized anyway, I guess I've never known. But even if I question the exact rankings that still leaves "they're all about equal" as a stronger possibility, as Panando points out.

And really I'm just thinking out loud, I'm in no position to take the time to do higher sample tests, so I'm grateful for any all !!Science!! when I'm not contributing.

Steel is still the safest choice vs normal enemies I guess?

The wiki should be updated with this information.

The differences between platinum, steel and silver are so tiny that it really doesn't matter. As a rule-of-thumb, just make all your weapons from steel if you can and you're good to go.

Testing for optimal enemy smushing is great. But out of curiosity, what would tue best (worst) hammer be for justice purposes?

Could we get a comparison between woods and adamantine?
Glumprong x Wagon x Feather x Adamantine?
So we could also get an idea of how wood density eschews the lethality of beatinga?

Feather wood's gonna be the worst by far, no doubt, but they won't use one of those. Adamantine is really, really bad, so's divine metal, but both can still cause pretty bad injuries.
