I found a ring labeled bone spear in on of the BFs in Act II. Actually I found two such rings... just lying on the ground. I did a printsceen then but then I used Ctrl+C on some other text before pasting the image form clipboard to some jpg file. The ring went the weapon section of inventory and when I equipped it, it went in the slot of a ring. It had two weights: 5 and 56. Though 56 was the effective weight increased when the ring was equipped.
Also I found some spare keys lying around there. I don't suppose they will be needed anywhere else in the game.
