The Dwarves Civilization is a funny one as a gurps player as it means there solidly in TL 5 Around the Napoleonic era weapons technology with fantasy elements plus TL5+1 with the combustion engine which requires advanced tooling and steel technology . Have the Chemistry understanding of crude oil. diesel and probably Kerosene/jet fuel.
What would be the rules for custom weapons and inventing? i assume the dwarves lack the percussion cap.
also rules for making dwarf armour cheaper due to ability to mass produce steel and iron.
as they seemingly have the Bessemer process for there large iron and steel construct and the ability to make it in the first place
