In the Team Fortress lore, Shakespearacles, the strongest writer to ever live, invented rocket jumping. A few centuries later, Abraham Lincoln invented stairs. He died while rocket jumping up them.
It's well known that ancient dwarves enjoyed the practise of banging rocks together through the shins of the elves. One day, the rocks sparked against each other and set the elf ablaze, and that is how dwarves discovered fire. They loved fire, and used it to set many, many elves ablaze.
From that day, it took 30 years to invent cooking.
This is a steel folding chair. All craftdwarfship is of the highest quality. It is encrusted with diamonds. It menaces with spikes of pigtail cloth. On the folding chair is an image of a dwarf and dwarves. The dwarf is making a plaintive gesture.
In my setting I dropped darkvision for dwarves because I wanted to make it scarce, but even the dwarves that don't study light or dancing lights use their many lighting inventions that were developed for underground exploration such as flairs and glow sticks, and gas lighting for their main settlements.
I also gave them all spiderclimb just because I like the way that fucks up how they'd build those settlements as down is only a necessary direction to know when you drop something, even their tankards work at all orientations and are basically sippy cups.
Oh yeah of course, if it's for personal use, always take everything you like from anywhere, and if it's for professional, I still think it's cool to take ideas.
The only thing is that if this is for 5e, you may wanna drop something from their stats such as dwarven resilience as this trait is reasonably powerful as it's effectively a hands free climbing speed which any marksman type character could cheese. One option is to make it the ability to cast spiderclimb at will, so it still has the limitations of requiring concentration (which is entertaining to imagine a dwarven bar brawl on the ceiling where everyone is knocking eachothers concentration out and falling to the floor, just to run back up) and it wouldn't work in an antimagic field too.
My setting has technology more-or-less equivalent to Earth's 17th century, and a big chunk of my inspiration is Neal Stephenson's Baroque Cycle. The books detail the steps that led to the industrial revolution so my setting also has similar early tech, aided by magic of course.
(Airships, for example, use magic derived from Resilient Sphere to make their balloons supernaturally rigid and impermeable, then instead of filling it with a lifting gas they just evacuate all air from it. Their hulls look like solid wood but they are instead a honeycomb structure made of giant spider silk sandwiched between thin wooden veneers to keep the cold air out, and reinforced with the occasional mithral spar. The propulsion is purely magic though, the props are powered by aetherosiphon engines. There are some secret military projects aimed at creating a fully-pressurized heavier-than-air skyship that can actually fly over the taller mountain ranges; since their passenger compartment is not pressurized, a standard skyship's maximal cruising altitude is 3-3.5 kilometers while a trained military crew can maybe get up to 4.5 km.)
"Oh tha's nice. Good grip on the bottom, large top to hit with, large middle for deflection. Too bad ya made it out of this weak wood or it would be an excellent weapon!"
"That is a chair you brute! Was a chair. Now it's fire wood..."
"Ya can sit on it too? Genius! Just needs a place to hold a drink and it could be perfect!"
I can just picture it now. A dwarven hell in a cell style match. Someone gets knocked back into an open chair in classic comedic WWE style and the whole crowd goes quiet. All you can hear is the collective thunk of thousands of chairs suddenly opening.
i'd like to see more settings where there is advanced tech, but non-humans just have a cultural aversion to them
dwarves that refuse to miniaturize things, gnomes that are open source absolutists, amish elves, halflings who don't give a shit so long as they can repair things themselves, goblins who don't really understand complex technology but will merrily fuck about with it until something cool happens, etc..
Note: For anyone who cares, of course this person doesn't have any evidence at all for this because none of it happen. They are however one of numerous alts of a known transphobe who has been banned from every major instance due to extreme hatred, bigotry, lying, and transphobia themselves.
