King black dragon scale

The King black dragon scale is an item dropped by the King Black Dragon that can be used to unlock the miniature-boss pet King Black Dragonling. 99 Summoning is not required to receive this as a drop, but it is required to summon the pet.

As with most boss pet items, the King black dragon scale follows the drop threshold system; it has a base drop rate of 1/2500 and a threshold of 500.
