I just (somehow) successfully implemented a magic wand that fires runes (at such a high velocity that knock backs are pretty much guaranteed, also the ammunition is almost never recoverable). The magic wand is made out of nine unicorn horns. I made the unicorn horns a weapon that drops on a unicorn death, so you can essentially either use it as a stabbing weapon fresh off the corpse or turn it into a "magic wand."
I also made unicorns have a "magic organ" that lets them grasp things, as well as letting them grasp things with their horns (removing the horns removes a grasp slot) so unicorns could very well use their ancestor's bones as weapons.
Earlier on, I made an element called "halflitite" that had an incredibly high melting point, made several clothing/armor items known as a "hazardous environment ____" with maximum coverage and "insulation" (what was the token for that again? coverage? I forget) that, when made of halflitite, made most of the user invulnerable to magma. This, sadly, did not include their fingers, toes, and for some reason facial features on females.
That brings me to my (incredibly juvenile) experiment of modding genitals onto humans. They weren't resistant to magma either. The tests with genitals and halflitite hazardous environment suits convinced me to just take the body parts for genitals out of the raws.
Otherwise everything was tame (for DF)
