To find the King black dragon, head to the Lesser demon cage to the west of the Lava maze. Enter the cage, climb down the ladder, go past the poisonous spiders, and pull a lever to enter the King black dragon's lair. The King black dragon is quite a popular monster to fight on loot share worlds, so you are likely to need to change worlds often so that you don't have competition with another group. If you are soloing the King black dragon it is advised to avoid loot share worlds altogether.
