King Black Dragon - OSRS Wiki

The King Black Dragon, commonly referred to as KBD, is a three-headed dragon located in his lair, accessible only through the deep Wilderness. Although the lair itself is not in the Wilderness, he is still considered a Wilderness boss by designation. The King Black Dragon has a combat level of 276, which makes him one of the strongest dragons in Old School RuneScape. Players should not take this foe lightly, and they should always take an anti-dragon shield as his dragonfire breath is very deadly without protection. The King Black Dragon can also be killed as an alternative for a black dragon Slayer task, except when assigned by Krystilia.
