It’s an insult to call them blacksmiths, they are automaton makers. Blacksmiths make blades… and swords… and axes… and armors. Hephaestus dwell in blast furnaces, and make intricate parts for automatons. True, they cannot make them function on their own but without them we would not have any automa cavalieres. Without crystals and the outset spell they would be inanimate metal sculptures, but no human blacksmith could do what a Hep does. Favorite automata ever. Bigas Hep!
