For Halloween you should make a silver skeletal gauntlet. That wraps around the wrist down to the tips of the fingers. Basically exoskeletal style but make the pieces look like actual bones in the hand and fingers. Maybe even add gold claws to the finger tips? Embed jewels into the knuckle joints.. I don't know if this makes any sense but what I am picturing would be an epic piece of gothic style jewelry. Either do ball joints or chains linking the bones, perhaps make it unisex adjustable. So any gender can wear it to fit them. I would totally commission you for the work but I don't have that kind of money. But the idea is yours if you want it. You could even do a flat black finish on the metal to make it look charred bone and use gold for the claws.
What technology ? He’s using very standard tools, with a lot of it being by hand to begin with. He’s not gonna go caveman and light a fire with kindling just for the sake of it.
