**'''Poison''': {{mes|You're badly scalded by the dragon's toxic breath!}}

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, KBD is still considered a Wilderness boss by designation, as players must enter the Wilderness to fight him. 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 dragonSlayer task, except when assigned by Krystilia.
Although he will always fight back when attacked, he has gotten bored over the centuries from adventurers attacking him, as he revealed to his good friend Bob the cat.
While the King Black Dragon's lair is entered from within the Wilderness, his lair itself is not part of the Wilderness, so players cannot attack each other in his lair. Completion of the Wilderness Diary also does not note his bone drops.
Players can pay 50,000 coins to open an instanced version of his lair (right-click Private option on lever), where it will be inaccessible by other players. This fee can be deducted directly from the bank; players do not need to carry coins on them to create the instance. Items dropped by the King Black Dragon in this instance will disappear after 1800 seconds (30 minutes), however items dropped by the player will disappear after the typical 180 seconds (3 minutes).
Warning: The entrance to the King Black Dragon Lair (aka KBD Lair) is located in the Wilderness; watch out for player killers!
Note: After climbing down the ladder near the lesser demons, players must pull a lever surrounded by poisonous spiders to access the lair.
::44s
The burning amulet(PKP Shop) teleports the player to the lava maze just south-east of the fenced area containing the entrance to the lair. This is the fastest and most reliable method of getting there.
Wilderness Obelisks can be used, but be wary that using them will make encountering high-level monsters or PKers more likely. Players who have high elo can choose the obelisk they wish to teleport to, namely the obelisk closest to the lair at level 44 Wilderness.
In addition to his damaging attacks, the King Black Dragon can also poison the player and reduce the player's stats. It is strongly recommended to bring anti-poison (Antidote++ is preferred) and stat-restoring potions such as super restores.
His dragonfire is significantly stronger than normal dragonfire, with a max hit of 65 with no protection, 15 with the anti-dragon shield or dragonfire shield, and is completely blocked with both the shield and antifire potion. Because the max damage is so high, the player should always have one of these shields equipped.
In addition to his regular dragonfire, the King Black Dragon has three unblockable breath attacks: Poison, Shock, and Freeze. A super antifire potion will only nullify all damage from the regular dragonfire, and the special breath will still deal up to its full 50 damage . With the anti-dragon shield or equivalent equipped, they only deal up to 10 damage. Protect from Magic does not protect against or reduce damage from dragonfire when an anti-dragon shield or equivalent is equipped. However, if no anti-dragon shield is equipped, Protect from Magic will reduce the max hit of these attacks from 50 to 20.
