My thoughts are halfway between Cheka and Moonhunter. I'd suggest reediting it as per moonhunter, then I'll vote. It is definately a good start, with lots of detail, but not enough in some areas. Go to Comment
As with all things, the GM should adjust the scarcity with an eye towards it's true impact.
A lot of posts I see can have very powerful affects on a campaign if allowed to occur in large quantities, but the same can be said for classic magical metals like Mithral and Adamantite. Some pretty good subs get low ratings because people extrapolate the impact of large quantities of the material.
The sensitivity of the material I have left somewhat deliberately vauge - the only hint provided is from the passage at the start:
Now, as I bring it near this enchanted helmet, do you see the change? Note how the goblet lightens in shade as I bring it closer?
It is up to you how strong that helmet was in magic, and how close he had to bring the goblet for it to change color. Go to Comment
