Deepsilver

Deepsilver is a very rare, magical metal found only near the roots of the earth. Although it is silver in color, it does not share the anti-shifter quality of true silver. It is, however, a far more effective weapon in general, as deepsilver is not only extremely lightweight, but also very durable. Much like deepgold, deepsilver is mined almost exclusively by dwarves and it is very expensive and hard to acquire, particularly in large quantities.
