I think the myth I heard was something along the lines of one bluesteel and two mithril makes an unobtainium, which just so happens to line up with the recipes we made up for our .exes back when they were a thing. Given the .exes came before these rumors (or at least when I heard them), that makes it instantly suspicious.

However, the real reason we know that unobtainium isn't craftable is that it has the reverse effect on non-admins. So the unobtainium armour lowers your walkspeed and makes your health 1, and the sword kills you when you hit someone with it. Even if it was craftable, nobody would make it.

In retrospect, Skull's recipe might not be so far off.
