Finally Stahlhaut, in my honest opinion, it makes no sense, how can reiryokyu make skin steel-like, I mean blut is making reiryokyu flow though blood vessels in order to harden them, but not make them steel. Actually this one would work, but only if it was something more akin so having skin cells absorb reiryokyu, making them very hard to penertrate instead of just making skin like steel. So in conclusion, if this one changed slightly, I could use it without bitching about the technicals XD

It doesn't make it steel, it makes it "steel-like" in that it offers a significantly enhanced durability, for multiple situations. If you'd bother to read the actual article and not just Prodi's summary, it would explain that it operates by having reishi surround the user's body, seeping into the skin and create a uniform force-field network that offers first-reaction protection. It's like wearing an invisible suit of armor.
