Coin of delving

A coin of delving is a magical copper coin used to determine distance when dropped.

Features
The coin of delving sheds dim light within a five foot radius. When dropped a distance greater than five feet, it rings melodiously when it hits a surface. Any creature that hears the ring knows the exact distance the coin dropped based on its tone.

History
Fresh Cut Grass had a coin of delving that he recovered from the body of his creator Dancer. They gave the coin to Orym while he was investigating a hole in the Weary Way Tavern in Jrusar. Orym dropped the coin, where it fell 1,200 feet and was lost.
