The Mithril dragon tail-bone is an item on the Odd Old Man's wishlist after the Fur 'n' Seek quest, and is dropped by Mithril dragons. It shouldn't take more than 10 kills to get a bone drop. 8 other tail bones are needed from Green Dragons, Blue Dragons, Bronze Dragons, Red Dragons, Black Dragons, Iron Dragons, Steel Dragons and Skeletal Wyverns to complete this miniquest.
