I'm having some trouble coming up with arms and armament for my fantasy world's dwarven race. I have a few ideas for what they could wield but I'd like a few more to really make this army feel Alive. Simply put: with the parameters I will set what are some suggested arms my dwarven race could use?
TLDR despite the dwarves having an engine I want their weapons tech to be sub-age-of-exploration level technologically. What are some ideas for weapons that employ this technology but don't exceed what would exist at this time for mankind with some extra limits as well.
No Black Powder (or limited): The dwarves, as one would assume, live primarily within mountain holds and underground caverns. For fear of cave-ins and wild fires both destroying their structures and eating up oxygen on lower floors they avoid using highly combustible materials at all costs which has lead to...
Steam Power: The dwarves have 'mastered' the steam engine and utilize its properties in both their mining operations and in their city design. It stands to reason their practice with this ancient and revered technology has since flowed into their advancements of military technology.
Agoraphobic Isolationists: The dwarves simply aren't interested in the surface world or holding territory upon it. To expand: they tend to either A) drill tunnels to other mountain ranges or B) dig further downwards. As such their weapons are more customarily suited for fighting wars of attrition within their tunnels or shock warfare to prevent their enemy from taking ground within their holds. I imagine because of this they'd limit range on weapons and not really employ cavalry or fast movers. That being said, if you can rationalize the use of such technologies feel free to let me know how.
Greed: These dwarves are as stereotypically greedy as they tend to be in other mediums. Whether that means they prefer mass cheap production or the production of only the finest of weapons likely varies from hold to hold. One thing I have as uniform among the dwarves is that they all keep a mass horde of gold and diamonds they dig up while working their mines which they will choose to defend over even the most vital military target.
Dwarven Forges: Due to their aversion to fire and explosives, dwarven forges tend to be very controlled environments with a heavy emphasis on procedure and safety making production slower but more methodical.
Tech Level Cap: This is where things get a little tricky; humans are meant to be generally the most technologically advanced race in this world, being in a late age of exploration tech level. By having an engine of any kind I understand the dwarves are already more advanced so my rationale is that this is a technology the dwarves haven't really attempted to expand upon or develop until recent years. Previously this technology was used more for quality of life and expansion methods within their tunnels and dwellings and only within the last hundred years or so have they really attempted weaponization.
Extravagant Competition: Humans, despite being at the age of exploration level of tech as mentioned before, do have a few more extravagant weapons at their disposal. My explanation for this is humanity's general unity over the many centuries in this world as well as their near constant state of war making a few technologies appear early or at least differently. Such examples are an extremely rare and volatile early tank, Gatling guns that are seldom employed outside the defense of the most key empire positions, revolver pistols for the most elite cavalry, flame throwers... relatively common to be honest because I'm a pyro. Off the top of my head those are all the 'out of period' technologies humans have. Hopefully this can set an upper limit for the dwarves extravagant tech.
Example: One weapon I had come up with to be a 'competitor' to the musket is a steam powered harpoon gun. The idea is the dwarf carries a large 'boiler' of sorts on his back that builds in pressure which they then use to fire a harpoon launcher type weapon. the reloading process is waiting for the boiler to build in pressure and the act of loading the harpoons into the 'gun'. Combined the amount of time to reload is comparable to a musket, the range is shorter, the penetration is better (?), and the accuracy is greater. Bonus Question: feel free to throw out ideas to improve/better specify the costs and benefits of this weapon and its design.
EDIT: 9/3/2019 8:04pm To be clear the dwarves do have access to fire they just prefer not to use it unless under very controlled methods. What they avoid using is combustion or more volatile flammable mixes.
