Scabbard of the Diamonds
Makes any sword stored within keen.
This is a plain-looking leather scabbard. Inside, however, are many diamonds encrusted into it, so that each time the sword is placed within and drawn out, it is sharpened. This grants the weapon keenness – critical hit occurs on a 19 or 20.
This was one of the gifts that King Asherbane gave to his sons.
