Indestructible Composition

From: Huntress
Description: I still can’t create an alloy for the universal blade. Something is missing. I remembered that mountain folk mined a metal with amazing properties. Even a heavy spear couldn’t break their thin, chain mail armour. And a line of shield bearers must have stood like an impenetrable wall. Will you look for it?
Completed: Interesting, interesting... what a small shield it is! Only a very short but extremely powerful warrior could wield it. And look at the framing, it’s true mithril! I’m not sure if the heat of my furnace is enough to melt it...
