This magical case protects and acts as a storage case for any and all bows, cross bows and any other armor or weapon that does not use a sheath. It even stores up the radiation and darkness of the Underdark itself in a way that protects an item kept in the case of darkness for up to 1 hour for every two hours it is stored in this case. Otherwise, this case can hold up to 40 pounds worth of items much like that of a bag of holding or a portable hole; although nothing bad will happen should the case be placed within any dimension space of magical item.
Thus a drow fighter could carry his drow sleep poison, 20 bolts and twin hand crossbows to the surface easily, and they would then remain fully functional and usable even in the light of midday as long as they didn’t remain out of the case for more than 1 hour for every 2 hours they were stored in Frizzan’s case of darkness. The noble drow archmage Frizzan was renowned for his manufacture and selling of these potent items, especially to drow settlements close to slaving routes and Skullport.
